Agree, the lure of food is worth putting up with the annoyance of the ultrasonic device. I would guess that if there's no food... then the mice will go somewhere else.

As others have said the dB output is not cumulative. This means the "dead" repellers may actually be emitting sound; only below the ambient level (which seems not very much). Either way, I am convinced of the ineffectiveness of these devices. Pictures don't lie.
I’ve never used one for mice, but I had a really REALLY REALLY bad cockroach infection that came from a neighboring apartment. I paid $10 on Amazon fairly positive it was a scam, I couldn’t use a spray for atleast 2 days and Amazon would deliver the device next day and the spray the day after. I received it and plugged it in at the worst point of infection where they make the most contact with me. Their numbers were greatly reduced and they didn’t come too close to me. I had to use it at the highest setting which was audible to me and annoying af to my dog but it worked. Finally the spray arrived and I was able to keep them at bay out if my apartment until an exterminator took care of the whole building.
It makes me so angry that these things are still being sold and they don’t work. Where are the consumer protection agencies banning these devices and suing for false clams.
Actually, the Federal Trade Commission did send out warnings to over 60 manufacturers in 2001, and even sued one for ignoring their warning. The problem is that these do work, in theory. I mean, wouldn't you avoid irritating noise? The problem is that the pests soon become acclimated and they lose their effectiveness. And future generations are not affected at all due to Natural Selection. But that's just like any pesticide. So the FTC can't ban them outright, and only tell them not to make outrageous claims. www.nachi.org/ultrasonic-pest-repellers.htm
You don't subtract the ambient level from the reading to determine the decibel level. As long as the noise source is above the ambient level that is the true decibel reading. If it is below the ambient level, you cannot measure it.
For the decibel reader, you might want to remove the foam screen cap. Thats there to prevent wind screen noise, but as you are indoors, would be entirely unnecessary, and at the range of sound you are recording, that foam screen cap may very well perform as an acoustic absorber. Also dB's are a non linear scale, 20 dB's is an extraordinary amount of energy, even an increase of 1 dB in the upper level is quite a significant and almost unsafe amount of energy. Also another thing is that High frequency noises are **extremely** directional. If your sensor is place even a little off access, you will get a significant decrease in decibel reading, this is part of the secret of how directional mics work to begin with.... which is another reason why emitters are ineffective. This speaks volumes that rodents will straight up eat within a choir of them. Good on you for exposing the fallacious industry of these sonic emitters.
You can 'expect' the pest repellerto work well if it has the ability to change the frequency of sounds that it emits. This is because mice and rodents are not used to changing frequencies, and therefore might get irritated due to it. The high frequency sounddoes not work if it encounters a solid obstacle in its way...
@@jasonbrindamour903 Well the dB part perhaps, but it still showed that a mouse will eat happily around a chorus of emitters, which is the real take away here
Excellent video! I've been thinking about getting one but was concerned that it might affect my cat. Now I see that it doesn't affect anything at all. Thank you.
Its shocking to me that Walmart, Home depot and many other reputable stores still sell that nonsense. I have used them several times. They absolutely DO NOT WORK!! ITS A TOTAL WASTE OF MONEY!!
Baiting in the way you did is like telling an alcoholic or starving person they need to cross a path with fire to get what they want. Eventually they’ll risk it when they’re hungry or thirsty enough? Cool and informative video. Back to the drawing board for me lol. I almost knew these would be a ‘gimmick’ although I’m sure some kind of science must back them and also one did half work.
The problem is that decibels don't measure frequency. Decibels are used to measure volume. FREQUENCY measure the number of times a sound wave passes a fixed point. Sound comes in waves and the number of times each second a new wave passes a point is the FREQUENCY of the sound.
hmm ... your video showed that mice ignore the electronic devices. What do you mean, "either way the mice love them"? What do the mice love if they are not affected by the electronic devices?
If the public wasn't so stupid, then psychics and mediums would go out of business. People are known to spend money on stuff that doesn't work, just because they are told it will.
Patty. Don't base your decisions on the say so of some random 'muppet' on the internet(!) Most of these people are posting for self gratification - & revenue - & know little or nothing about what they comment on. Yes. By all means be cautious - but always cross reference & check the info given with other sources.
Hey Amigo thanks for the effort you put into this. Most of what I read says that these ultrasonic devices don't provide much assistance in repelling mice for various reasons--placement, gradual acclimation to the sound produced, etc. I wonder though how accurately a standard db meter can detect volume( or more correctly sound pressure level-SPL). Decibel meters seem to be aimed at measuring the SPL of frequencies that humans can hear (20hz to 20,000 hz) to aid in the prevention damage to human hearing in noisy environments. Measuring the sound pressure level of frequencies beyond that range( so called ultrasonic) probably requires a different instrument. Perhaps the one repellent device that seemed to be "working" was emitting a frequency that the meter could detect. No criticism intended here just some fun musing. The bottom line is the little buggers are winning.
The mice and bugs become desensitized to the sound. It's like when you hear a knocking in your car's engine at first you constantly hear it then after a few days it magical goes away. But it really didn't its just your brain tuning out the noise.
@@pc3983 This. All the animals of my life came to me. (Apparently they are really good at recognizing a sucker. Must be some sort of animal survival instinct.)
YEAH, I THOUGHT OF THAT TOO, BUT IM OLD AND I DONT FEEL LIKE I WANT ANY RESPONSIBILITY WITH A PET AT MY AGE. SO I GUESS I LL HAVE TO THINK OF SOMETHING ELSE. WOULDNT IT BE GOOD IF THERE WAS SOME KIND OF MECHANICAL DEVICE THAT WAS MADE BY SOMEONE THAT WORKED ON BATTERIES AND WHEN THIS DEVICE DETECTED A MOUSE IT WOULD GO AFTER IT AND KILL IT. THE SPEED OF THE DEVICE WOULD HAVE TO BE LIKE LIGHTNING. MAYBE SOME TYPE OF AUTOMATIC SLING SHOT THING WHEN ANY MOVEMENT WAS NEAR IT, IT WOULD GO OFF.
I have some pretty big sound emitters to keep critters from under my deck. There’s a motion sensor and it screams a high pitched eagle sound that my dogs alerted too for the first few days they set it off. I haven’t had any skunks or raccoons under there in a year, could be coincidence, but anecdotally they seem to work.
@1:58-2:00 Looks like you have 2 spiders as well. 1 immobile to the left & 1 moving to the right. Watch closely for the change on the one to the right. (The one on the left is visible, but doesn't move.)
This doesn't change the conclusion, but the sound meter almost certainly has limited bandwith, so it wouldn't pick up much (if anything) at those frequencies. I'd guess the one it does give a reading for emitts EM noise. Look at the data sheet for it, it should have a frequency range specified. Outside that it likely drops off steeply.
Your device cant check over 12 kHz soynd frequency. On the other hand the ultrasonic repeller frequency is more than 20KHz . So you wrong . You cant check ultrasonic with sound meter tester.
2:55 You cannot add decibels by simple arithmetic addition, because they are logarithms. If you have two sound sources, each producing, say, 50dB at a distance of 1 meter, turning them both on simultaneously will double the power, and the doubling of power in decibels is 3dB, so the resulting sound intensity is 53dB, not 100dB, which you would get by adding the numbers together.
Great video BUT would there have been MORE mice if you didn't have the repeller? Also, putting food in front of a hungry mouse might be a temptation it cannot resist even if it needs to endure discomfort. If there was no food lying around and the repellers were on then there may be no mice around..
dB is a logarithmic scale, so in order to subtract the ambient noise you would first have to convert into sound power, then subtract and then convert it back to dB. But for the dB's you measured the end result should be almost identical to the original measurement (every 6dB the power drops by a factor 1/2, so for a 30dB difference means a factor 1/64 difference which translates to only a 0.1 dB reduction so negligible).
I enjoyed this video especially the hidden camera with the peanut butter set up is it possible you could do the same test using the fresh cab stuff..... would love a visual if they'll even go near the area even for food
Because electricity doesn't flow as well through an extension cord??? You would probably need a $1000 device to even detect a difference between the wall outlet and the extension cord power. They probably tell you to plug into the wall because plugging it into a surge protected power strip would definitely be a problem - it would work even worse than the current "doesn't work at all"!
How about for bugs, like spiders, roaches, ants, fly's and mosquitos? I took these to the Philippines. And using a 500 watt inverter for each. I placed 1 in each room and 2 in the kitchen. I didn't see roaches any longer. They were behind a baseboard in the kitchen. A mouse came to my home in a cargo box I had shipped from the U.S. I used a glue trap and that caught the mouse in one day! Mice in the Philippines look lots skinnier and different than U.S. mice. I held the glue trap up close to examine the mouse before trashing it. The eyes looked black and the surrounding part looked like it was dripping white. No kidding, looked like someone painted the eyes and the eyes were watery or melting. Very odd and gross to a certain extent. But no bugs once I turned the emitters on at night.

This is glorious, been searching for "pest control estimate template" for a while now, and I think this has helped. Ever heard of - Vaniam Tonatthew Formula - (just google it ) ? Ive heard some decent things about it and my m8 got excellent success with it.
That was my only hope to get rid of mice between first and second floor, as I don't have direct access to the space inside the ceiling. Now I don't know how to get rid of the suckers. They never show up in open space, I only hear their tiny steps between floors all the time.
Found the same thing with big speakers. Just get a sound file or play a 20kHz UA-cam video really loudly. Works better (I can hear them squeak and run after about 60 secs) and costs nothing. It's not a permanent fix but it seems to have an effect.
I was told by a restaurant owner that the ultra sonic rat and roach killers do not work, back in 1985, after seeing a cockroach run across one of the devices. Total FAIL!!! Then 2 years ago I heard about using 432htz to calm down the brain and produce sleep. I was using my phone to send the sound to my stereo, which made it much louder, so 432htz worked, when amplified and then I tried the rat killers, and in 20 minutes the rat sounds stopped, and did not return. So the idea works, but you have to modify the system so it is very loud, at least for rats and mice ect... Brother James OSB OFS OSC
I have a pest repeller. It doesn't work. There's a mouse that won't leave my room and it avoids the traps with peanut butter that I set for it. I also leave the door open for a bit and it doesn't take the opportunity to scurry out. I know that it's starving because I hear it chewing into things and I hear it squeak now and then. It's getting really irritating.
Thanks! I save myself ,$35 99,on the purchase,back to the old convention way. The merchant must hate you,but we love you for your honesty thanks again.
Well I had a mouse coming into my kitchen. I did a lot of research online , and ultra sonic pest repellents do work. First the brand matters. Also did you read the instructions? Do not use with an extension cord. Must plug into wall. I downloaded a app to my phone and it worked great til I could get a three pack at Walmart.
With mine it says when you plug it in a wall it has to be horizontal. In other words with the two prongs side by side instead of on top of each other. Then it has to be at least three feet off the floor. I had to use mutli outlets to hang to get this to work. So far the front one works. I'm still figuring out the back one. But I also use a good inside/outside pest spray.
I have some experience with the sound level meters and I think they are poor at higher frequencies. That image of the mouse with repellents is hilarious though.
Nice and informative, and although I believe the units have little effect, the test method used is not really done properly. 1- First of all, the frequency range of the SPL is selected to reflect our hearing range, so the meter might not be within range of the devices, and one should ascertain that it can actually measure in the appropriate range, Sub-sonic or ultrasonic. The unit shown is many for human range. 2- Most SPL meters have a range from 20Hz to 20kHz, and have weightings, i.e. roll-off filters that limit the bandwidth, known as A-B-or C weighted readings. 3- The sound emitted by each device should all be measured at the same distance. At the distance shown, there is a massive difference even at a half-inch, likely around 10-20 dB each time you even marginally move the microphone. Think of how headphones change in sound pressure when you even move them a fraction from your ears. 4- room noise is never deducted from the reading, The device outputs the reading you see. Room noise is irrelevant to the sound pressure level of the device you are measuring, except if the output is below residual room noise. So to be honest, this test really didn't evaluate functionality, other than establish that either the mouse was deaf, or no longer cared and was really hungry. The mouse learned that the sound was just annoying, and not a threat. Sorry but you can't always believe what you see on the internet. The old sound engineer....
1. Keith Vanderkley has rightly pointed out. I am adding few lines on redundancy of Sound Level Meter (SLM) test conducted. The pest repellers generate ultrasonic range of frequencies (usually, 20 kHz-158 kHz - audible by pests), which is higher than human hearing range (20 Hz to 20 kHz). Moreover, the SLM used looks like an ordinary one, which may not responsive for frequencies more than 8 kHz or 16 kHz. Metaspencer may check the specs of SLM and verify its actual range of frequency response. Interestingly, a pest repeller must be faulty if someone can detect any sound (either by physical hearing or with an ordinary SLM), as that repeller is not supposed to generate any frequency below 20 kHz. In that case, the device will be harmful for human being, since prolonged exposure to a noise within audible frequency will create annoyance, distraction and other physio-psychological disorders. 2. Effectiveness of any repeller can be assessed by practical application. Of course, any influencing factors (as also mentioned by Keith Vanderkley) must be excluded, which a bias the effect.
I was sick and tired of the traps and decided to get a real cat for my mother and let me tell you he definitely did the job!😀👍🏾. Unfortunately after over 5 years we had to give him up but he's at a good home. Live cats are much much more efficient. Thank you for your video because I was thinking about getting one of these ultrasonic sensors for my place but i think ill just invest in getting a cat 😆👍🏾. God Bless you and your family!.🙂🙏🏾❤🕊
Been looking for this roach with my brother for like 45mins and we just thought to look up audio of roach repellent and in likw within 2 mins no joke it came out.
I'm not American so i don't know any of those, i had like one mouse in my home at least i only spotted them one at a time, i got 3 different traps but nothing, someone recommended a particular sonic repellent thing, so i got it the thing cost £25 on Amazon. It said in the instructions it can take upto six weeks for them to go as they are stubborn especially if they have babies. The first few weeks i spotted the mouse more at crazy times, the device was in my kitchen which is were they came in and i had a mouse bounding round my living room in broad daylight, i thought maybe its trying to get away from the sound, then i just stopped seeing it or seeing any signs from it, not seen or heard anything for a couple of months now.
Just to be clear, your math on the dB was not 100% correct. It's not added to the ambient sound... In this case, your room was abut 35 dB (noise floor) and you had a device produce 75 dB. It's not additive i.e. 75-35 = 40, the device produced 75. If your noise floor was 10 dB, you still would have read 75 on the meter.
Decimeters cannot detect ultrasonic sounds. If there was a moving part in that first one, and you put the detector right on top of it, it would register a noise.
Thanks for your efforts. I was always convinced that these gadgets were too good to be true and probably total BS. good to see a logical analysis with dB tester.
Yes, I have a perfect and complete solution for you. It doesn’t work on mice unfortunately, but if your problem is roaches, it absolutely works on them. And if you have pets, it’s great because it doesn’t harm them. It’s called Diatomaceous Earth. It’s cheap, it’s amazing, and it works like a charm. I moved into an apartment building once that turned out to be infested with roaches. Horrible. Asked the landlord to pay for spraying (even though I didn’t really want to, because I don’t think spraying hormone disrupters, etc, is good for us either, especially women). But I got it done anyway, and it did nothing. Finally learned about diatomaceous earth. It’s so cheap, I gave a cup to all my neighbors. No more roaches within 3-5 days.
You're supposed to remove any food sources that might be available to there mice.... When there is plenty of food around the incentive for the mice to stay around outweighs the annoyance of the loud high pitch sound... Shit if I was getting fed, free heat, room and board but had to put up with some annoying sounds I'd probably stick around too...
@@metaspencer most of them are probably junk. I do know from experience, my parents tried them back when I was in my early teens when the new upstairs neighbors brought cockroaches. The ones they bought did indeed work... Will they work for rodents? I'm not sure, but I would assume it has to work on some kind of risk-annoyance/reward system for them before they decide to look for a new home to pull a Putin on.
Would the decibel reader pick up the low electrical charge from the one you plug in? Maybe you think it's ultrasonic but in reality it's just the electrical buzz it's picking up instead.
One thing you should know.....1 noise making 60 db and add another device making 60db does not equal 120 db. It would be 60 db. So your first device was actually putting out the registered amount. The higher number only cancels the lower so if it were dead quiet the readings would still be the same. just sayin
Q. The one we just bought says it must be plugged x inches above the floor. It is like over 30”! And it says it must be plugged into a vertical outlet, upright… not a sideways outlet. We’re in a small apt, and most of the outlets are only a foot above the floor. Can anyone explain why it would not be all right to plug it into an outlet that is only a foot above ground? Thanks.
@@metaspencer Thank you for your quick, savvy response. Had we seen this video, we probably would not have bought them. Thus far, the only thing that had worked is a live catch metal cage with a trigger. Mouse ventures in, finds treats on platform, and the door shuts. Then i take them outside to release them. Sigh. I waa hoping the sound deterrent would work.
My daughter sent me a Riddex after suffering a very bad spider bite at our house. The decrease in spider webs was very noticeable. Also i found a mouse in the middle of my dining room so disoriented I was able to put a jar over top of him and take him outside,
If they are ultra sonic that would mean they are super high frequency right? Based on info for stereo systems.... low frequency is referred to as low on no directional, while high frequency is directional. So I wonder how effective ultra sonic emissions are if the are uni directional. Meaning if the sounds is dispersed almost straight out of the emitter, do they have to stand directly in the path to be deterred by it?
I check my sticky traps every hour I only have 4 if there's a mouse in one I kill it. I'm a hunter I don't give a sht about people who get butt hurt about this
that meter will not read ultrasonic sound, you need a special designed meter for that. I dont know what it is reading maybe just the noise of the device, also you dont add decibels that way, what ever the meter reads that is the level the device is emitting.
Sorry. Decibel readings are not directly additive. So, for that first reading you did on the big unit, 75 decibels would be its output (minus 0.00034). I knew a guy back in the '70s who claimed that he caused his neighbor to get rid of his never-ending-barking dog (one of those dogs that barks for sport and it doesn't bother the owner) by hooking up an aquarium pump to a dog whistle via a short length of tubing and setting the pump (in a hole) and whistle (at the surface but camouflaged) as close to the property line as he could. .
Thank you for video. It is good that you use a sound meter to evaluate DB level of each device. As far as I know, a quite room is appr 20 DBs. Conversation is 45 DBs. Busy traffic noise is 70 DBs. So anything below 70 will be ok for humans. However, since rats can normally hear ultrasound in its lifetime, so an additional amount of ultrasound produced from small device would be neglected. Anyhow I have been using this device for 2 weeks, I observed the different. It works under my carport. By the way, in your tests those with no signal or 5 DB should be broken circuit board.
No! I've bought and tried electronic devices and they continued to tear the sound deadening material under the vehicles hood and they just seems to walk by it and get the material they want. SO nope, they don't work.
"Manufacturers of ultrasonic pest repellers make claims that may be unsupported by scientific testing. In fact, more than 60 companies received warning letters from the FTC in 2001 stating that “efficacy claims about those products must be supported by scientific evidence." Two years later, one company was sued by the FTC for violating its warning." [INTERNACHI]
High frequencys are very directional opposite than low that are omnidirectional saying that it only will work depending in the direction if is diffused also will the decibels. In other words is like having a pointer laser trying to kill mouses.
I installed an ultrasonic pest repellent in the kitchen and discovered the roaches actually congregated around the darn thing like it had candy on it. Weird. Save your money.
Here’s another suggestion, that I believe works like a charm!! Order (or go buy at walmart, academy sports, dicks outdoors or whatever sporting goods store, or online) some Red Fox Urine (others have used Grey Wolf Urine, and some Coyote Urine, just depends what is available, cheap, and ensure that you select one for a critter that isn’t likely to live in your area so you aren’t “luring” one to your home!!) and it repels critters that are its prey (costs from $10-$20 for several ounces in a bottle or spray bottle, aka plenty for your purposes), as soon as they (mice, rate, raccoons, small to mid sized critters) smell the larger predator urine (and typically it gets dark enough as most are naturally nocturnal that they can hall buns), they evacuate where ever (your home, grarage, horse stable, etc.) in order to get away from whatever predator they smelled that might be around hunting and trying to eat them! We used this solution when a raccoon decided to tear open a section and then hide under our porch outside and to ensure that it didn’t go under and stay under our house. Once applied, as soon as it got dark, that thing (the raccoon) could be heard ripped its way out and then it hauled you know what!, and never came back!! You have to apply the urine to somethiing or directly to your house at the 4 corners (we did all 4 corners and then middle on outside our house along with our porch, so in 6 spots, 9 total so perhaps a bit of overkill??..LoL!!) the urine smells awful, and of course it fades with time and so must be reapplied regularly to continue to work. Also, you have to wait for a dry (non-rainy, non-wet day as water washes the scent away if applied on the outside of your house or if whatever you spray it on gets wet) day.There are various “scent keys” you can hang up that shouldn’t get wet if you hang them up off the ground or obviously where water or rain or water run off can not reach them (or get creative like we did as decribed below). Then reapply, it one week later, so 1x a week for 1 month. Then every 2 weeks, and then once a month, and repeat. We decided to spray some onto tennis balls that we had driven nails into and we tied fishing line around the nail, so we could then easily attach the fishing line at one end to something on the side of the house. That way, we sprayed the tennis balls, tossed them under the house, and later we could easily retrieve the tennis balls by pulling on the string, and reapplying the spray and tossing them back under the house. Obviously, using plastic gloves, and definitely standing up wind!! Also, you can spray the red fox, grey wolf, (large predator) urine onto cotton balls, and place around your yard or inside your garage or roof (it will stink!!), various sporting good stores, or walmart or online, etc. also sell “lure” scent traps for hunters, which are key/pin things that basically are or have cotton or cloth strips in a P or T shape and you can hang them whereever with string, the whole point is that “prey” are repelled by the smell of a large (in its eyes) “predator” moving in, so it immediately moves “out” as it doesn’t wish to be eaten. So, there ya go!... Lastly, this isn’t a soultion for “inside” your home for obvious reasons. For the slow to comprehend, what I mean is that, because spraying animal urine in your house will make it stink to high heaven (even outside or under your house you’ll smell it to a point depending how thick your walls are or floor...aka mobile home verus a brick structure), and also, spraying animal urine inside your house isn’t exactly sanitary!...Trust me, the smell will drive you out before the grossness of it being unsanitary!! This solution is safe for pets, although I’m not sure it they’ll be happy about it, but it definitely won’t harm them physically, because it is only smell/scent! And of course, other than the smell, and as long as you do not touch it, use plastic gloves and wash your hands immediately after applying it, etc.. it is safe for humans too!! Let me know if you have as much success as we have had...(and what with, which type critter)... Hopefully, this works for you too! Good Luck!
Can I apply this pradator scent inside my two car garage? My two dogs live in the garage so will it drive them crazy? I'm having a mice problem because of the dog food. Can I get this scent on Ebay?
Thank you for doing this video. My question is this, did you try it only one at a time? I know from producing music that when you have two soundwaves that are the same, they can actually cancel each other out. I am wondering if that is a possibilty. I have a rodent running around my walls, so I am looking for a solution. Did you find one yet?
@@metaspencer it'd better will footage that u try it one by one..since what we can see in here u only show the result with two devices operational at the same times.
If anyone wants to buy these, just message me. I'll lend my mom to you for a fee and she'll keep on nagging for hours and output more decibels than these devices.
Seems like those ultrasonic devices are just providing the mice with some soothing techno music while they dine.

Frequency is measured in Hertz and Decibel is in pressure level (SPL), I don't believe we can use the db reader to detect the frequency of the sound.

Agree, the lure of food is worth putting up with the annoyance of the ultrasonic device. I would guess that if there's no food... then the mice will go somewhere else.

This is why it is important not to leave food out in addition to the electronic traps.

hilarious. you've got it figured out
As others have said the dB output is not cumulative. This means the "dead" repellers may actually be emitting sound; only below the ambient level (which seems not very much). Either way, I am convinced of the ineffectiveness of these devices. Pictures don't lie.
Well said man. Thanks for taking the time to comment
I’ve never used one for mice, but I had a really REALLY REALLY bad cockroach infection that came from a neighboring apartment. I paid $10 on Amazon fairly positive it was a scam, I couldn’t use a spray for atleast 2 days and Amazon would deliver the device next day and the spray the day after.
I received it and plugged it in at the worst point of infection where they make the most contact with me.
Their numbers were greatly reduced and they didn’t come too close to me. I had to use it at the highest setting which was audible to me and annoying af to my dog but it worked.
Finally the spray arrived and I was able to keep them at bay out if my apartment until an exterminator took care of the whole building.
A powerful story! Thanks for sharing it
It makes me so angry that these things are still being sold and they don’t work. Where are the consumer protection agencies banning these devices and suing for false clams.
No kidding. Such a scam
See my post above
Actually, the Federal Trade Commission did send out warnings to over 60 manufacturers in 2001, and even sued one for ignoring their warning. The problem is that these do work, in theory. I mean, wouldn't you avoid irritating noise? The problem is that the pests soon become acclimated and they lose their effectiveness. And future generations are not affected at all due to Natural Selection. But that's just like any pesticide. So the FTC can't ban them outright, and only tell them not to make outrageous claims. www.nachi.org/ultrasonic-pest-repellers.htm
They are the ones inventing them and their Board of directors owns a company that makes them. Insider trading
This is America the most corrupt Western country. It is land of the corporations not the land of the free or the brave anymore.
I’m just going to burn the house down 🤷🏽♂️
You don't subtract the ambient level from the reading to determine the decibel level. As long as the noise source is above the ambient level that is the true decibel reading. If it is below the ambient level, you cannot measure it.
For the decibel reader, you might want to remove the foam screen cap. Thats there to prevent wind screen noise, but as you are indoors, would be entirely unnecessary, and at the range of sound you are recording, that foam screen cap may very well perform as an acoustic absorber. Also dB's are a non linear scale, 20 dB's is an extraordinary amount of energy, even an increase of 1 dB in the upper level is quite a significant and almost unsafe amount of energy.
Also another thing is that High frequency noises are **extremely** directional. If your sensor is place even a little off access, you will get a significant decrease in decibel reading, this is part of the secret of how directional mics work to begin with.... which is another reason why emitters are ineffective.
This speaks volumes that rodents will straight up eat within a choir of them.
Good on you for exposing the fallacious industry of these sonic emitters.
You can 'expect' the pest repellerto work well if it has the ability to change the frequency of sounds that it emits. This is because mice and rodents are not used to changing frequencies, and therefore might get irritated due to it. The high frequency sounddoes not work if it encounters a solid obstacle in its way...
This also depends on the detector response range. If the detector itself does not respond to that frequency, it may showing a fault result
Decibel meters are not meant to "hear" the frequencies involved.....this test does NOTHING.
@@jasonbrindamour903 Well the dB part perhaps, but it still showed that a mouse will eat happily around a chorus of emitters, which is the real take away here

Cool and informative video. Back to the drawing board for me lol. I almost knew these would be a ‘gimmick’ although I’m sure some kind of science must back them and also one did half work.
The problem is that decibels don't measure frequency. Decibels are used to measure volume. FREQUENCY measure the number of times a sound wave passes a fixed point. Sound comes in waves and the number of times each second a new wave passes a point is the FREQUENCY of the sound.
+academicjock ... either way the mice love them
hmm ... your video showed that mice ignore the electronic devices. What do you mean, "either way the mice love them"? What do the mice love if they are not affected by the electronic devices?
I was just saying that the devices clearly don't deter mice. The fact that they emit either no or very low volume emissions could be part of that
academicjock because I don't understand what you're saying I'm going to take it as disrespect, watch your mouth and help me with the sale

5:35 best is Svinz with 20-40dB emission volume. Low cost ones were very little volume
Hey Amigo thanks for the effort you put into this. Most of what I read says that these ultrasonic devices don't provide much assistance in repelling mice for various reasons--placement, gradual acclimation to the sound produced, etc. I wonder though how accurately a standard db meter can detect volume( or more correctly sound pressure level-SPL). Decibel meters seem to be aimed at measuring the SPL of frequencies that humans can hear (20hz to 20,000 hz) to aid in the prevention damage to human hearing in noisy environments. Measuring the sound pressure level of frequencies beyond that range( so called ultrasonic) probably requires a different instrument. Perhaps the one repellent device that seemed to be "working" was emitting a frequency that the meter could detect. No criticism intended here just some fun musing. The bottom line is the little buggers are winning.
Yeah, I think you're right about the frequencies but the dang things sure don't keep the mice away
those companies should be sued for scamming us
Scaling?
@@ianlee4850 scamming
There are being sued..I orderd the Bell& Howell ones and received a letter to partake in lawsuit against them...they don't work..look into it
The mice and bugs become desensitized to the sound. It's like when you hear a knocking in your car's engine at first you constantly hear it then after a few days it magical goes away. But it really didn't its just your brain tuning out the noise.
I have a better method. When I hear a rod knock in my truck, I just turn up the stereo with Kid Rock. No more rod knock.
Boom boom!
But only one mouse showed up as compared to the 100’s of mice you had before. It takes like 4 weeks for the sounds to work.
So like the rodents continue to come around until they finally get tired of the sound (if any), and then leave?
Yeah i guessed , these devices are just good for the revenue generation for the manufacturers

Thank you for taking the time to check these out and the trail cam footage.

I have some pretty big sound emitters to keep critters from under my deck. There’s a motion sensor and it screams a high pitched eagle sound that my dogs alerted too for the first few days they set it off. I haven’t had any skunks or raccoons under there in a year, could be coincidence, but anecdotally they seem to work.
Wow, sounds like quite a setup!
@1:58-2:00 Looks like you have 2 spiders as well. 1 immobile to the left & 1 moving to the right. Watch closely for the change on the one to the right. (The one on the left is visible, but doesn't move.)
+RackAttackGamer ... good eyes!
This doesn't change the conclusion, but the sound meter almost certainly has limited bandwith, so it wouldn't pick up much (if anything) at those frequencies. I'd guess the one it does give a reading for emitts EM noise. Look at the data sheet for it, it should have a frequency range specified. Outside that it likely drops off steeply.
Your device cant check over 12 kHz soynd frequency. On the other hand the ultrasonic repeller frequency is more than 20KHz .
So you wrong .
You cant check ultrasonic with sound meter tester.
2:55 You cannot add decibels by simple arithmetic addition, because they are logarithms. If you have two sound sources, each producing, say, 50dB at a distance of 1 meter, turning them both on simultaneously will double the power, and the doubling of power in decibels is 3dB, so the resulting sound intensity is 53dB, not 100dB, which you would get by adding the numbers together.
Interesting! Thanks friend
Awesome. you saved me money and from feeling like a sucker.
Great video BUT would there have been MORE mice if you didn't have the repeller?
Also, putting food in front of a hungry mouse might be a temptation it cannot resist even if it needs to endure discomfort.
If there was no food lying around and the repellers were on then there may be no mice around..
They Should Be Class Action Sued..
Damn Thieves..
dB is a logarithmic scale, so in order to subtract the ambient noise you would first have to convert into sound power, then subtract and then convert it back to dB. But for the dB's you measured the end result should be almost identical to the original measurement (every 6dB the power drops by a factor 1/2, so for a 30dB difference means a factor 1/64 difference which translates to only a 0.1 dB reduction so negligible).
+K van der Veen .... interesting!
I enjoyed this video especially the hidden camera with the peanut butter set up is it possible you could do the same test using the fresh cab stuff..... would love a visual if they'll even go near the area even for food
Hey, thanks for the nice comment! Yeah, I had fun setting up the hidden camera. I'll have to plan out a second test. Great idea.
I have one and its works for me but the directions said they must be plugged directly into the wall(not into an extension cord).
Because electricity doesn't flow as well through an extension cord??? You would probably need a $1000 device to even detect a difference between the wall outlet and the extension cord power. They probably tell you to plug into the wall because plugging it into a surge protected power strip would definitely be a problem - it would work even worse than the current "doesn't work at all"!
How about for bugs, like spiders, roaches, ants, fly's and mosquitos? I took these to the Philippines. And using a 500 watt inverter for each. I placed 1 in each room and 2 in the kitchen. I didn't see roaches any longer. They were behind a baseboard in the kitchen. A mouse came to my home in a cargo box I had shipped from the U.S. I used a glue trap and that caught the mouse in one day! Mice in the Philippines look lots skinnier and different than U.S. mice. I held the glue trap up close to examine the mouse before trashing it. The eyes looked black and the surrounding part looked like it was dripping white. No kidding, looked like someone painted the eyes and the eyes were watery or melting. Very odd and gross to a certain extent. But no bugs once I turned the emitters on at night.

They aren't loud enough plugged my phone into big speakers with the mouse repellent noise and it scares them away for a little while
Found the same thing with big speakers. Just get a sound file or play a 20kHz UA-cam video really loudly. Works better (I can hear them squeak and run after about 60 secs) and costs nothing. It's not a permanent fix but it seems to have an effect.
I was told by a restaurant owner that the ultra sonic rat and roach killers do not work, back in 1985, after seeing a cockroach run across one of the devices. Total FAIL!!! Then 2 years ago I heard about using 432htz to calm down the brain and produce sleep. I was using my phone to send the sound to my stereo, which made it much louder, so 432htz worked, when amplified and then I tried the rat killers, and in 20 minutes the rat sounds stopped, and did not return. So the idea works, but you have to modify the system so it is very loud, at least for rats and mice ect... Brother James OSB OFS OSC
Interesting!!
I have a pest repeller. It doesn't work. There's a mouse that won't leave my room and it avoids the traps with peanut butter that I set for it. I also leave the door open for a bit and it doesn't take the opportunity to scurry out. I know that it's starving because I hear it chewing into things and I hear it squeak now and then. It's getting really irritating.
They might have gotten used to the noise
Thanks! I save myself ,$35 99,on the purchase,back to the old convention way. The merchant must hate you,but we love you for your honesty thanks again.
You'll win out over those mice ... it just takes determination
Well I had a mouse coming into my kitchen. I did a lot of research online , and ultra sonic pest repellents do work. First the brand matters. Also did you read the instructions? Do not use with an extension cord. Must plug into wall.
I downloaded a app to my phone and it worked great til I could get a three pack at Walmart.
With mine it says when you plug it in a wall it has to be horizontal. In other words with the two prongs side by side instead of on top of each other. Then it has to be at least three feet off the floor. I had to use mutli outlets to hang to get this to work. So far the front one works. I'm still figuring out the back one. But I also use a good inside/outside pest spray.
Which brand do uou recommend?
my bunny hopped out of my room when you tested the first repeller...i guess theres that.....
bunny! that's awesome
I have some experience with the sound level meters and I think they are poor at higher frequencies. That image of the mouse with repellents is hilarious though.

A lot of the mics on these dB measuring gadgets only go up to 8khz, which is definitely not supersonic.

Hahahaha
Okay, I laughed at that way more than I should have😂
😆😆😆😆
That’s pretty much what happens.
Nice and informative, and although I believe the units have little effect, the test method used is not really done properly.
1- First of all, the frequency range of the SPL is selected to reflect our hearing range, so the meter might not be within range of the devices, and one should ascertain that it can actually measure in the appropriate range, Sub-sonic or ultrasonic. The unit shown is many for human range.
2- Most SPL meters have a range from 20Hz to 20kHz, and have weightings, i.e. roll-off filters that limit the bandwidth, known as A-B-or C weighted readings.
3- The sound emitted by each device should all be measured at the same distance. At the distance shown, there is a massive difference even at a half-inch, likely around 10-20 dB each time you even marginally move the microphone. Think of how headphones change in sound pressure when you even move them a fraction from your ears.
4- room noise is never deducted from the reading, The device outputs the reading you see. Room noise is irrelevant to the sound pressure level of the device you are measuring, except if the output is below residual room noise.
So to be honest, this test really didn't evaluate functionality, other than establish that either the mouse was deaf, or no longer cared and was really hungry. The mouse learned that the sound was just annoying, and not a threat. Sorry but you can't always believe what you see on the internet.
The old sound engineer....
1. Keith Vanderkley has rightly pointed out. I am adding few lines on redundancy of Sound Level Meter (SLM) test conducted. The pest repellers generate ultrasonic range of frequencies (usually, 20 kHz-158 kHz - audible by pests), which is higher than human hearing range (20 Hz to 20 kHz). Moreover, the SLM used looks like an ordinary one, which may not responsive for frequencies more than 8 kHz or 16 kHz. Metaspencer may check the specs of SLM and verify its actual range of frequency response. Interestingly, a pest repeller must be faulty if someone can detect any sound (either by physical hearing or with an ordinary SLM), as that repeller is not supposed to generate any frequency below 20 kHz. In that case, the device will be harmful for human being, since prolonged exposure to a noise within audible frequency will create annoyance, distraction and other physio-psychological disorders.
2. Effectiveness of any repeller can be assessed by practical application. Of course, any influencing factors (as also mentioned by Keith Vanderkley) must be excluded, which a bias the effect.
I was sick and tired of the traps and decided to get a real cat for my mother and let me tell you he definitely did the job!😀👍🏾.

I love your cat story! Makes perfect sense. Take care
do you measured it with the dB(A) setting? this is calibrated to the human hearing capabilities...
Been looking for this roach with my brother for like 45mins and we just thought to look up audio of roach repellent and in likw within 2 mins no joke it came out.
Ha!
I'm not American so i don't know any of those, i had like one mouse in my home at least i only spotted them one at a time, i got 3 different traps but nothing, someone recommended a particular sonic repellent thing, so i got it the thing cost £25 on Amazon. It said in the instructions it can take upto six weeks for them to go as they are stubborn especially if they have babies. The first few weeks i spotted the mouse more at crazy times, the device was in my kitchen which is were they came in and i had a mouse bounding round my living room in broad daylight, i thought maybe its trying to get away from the sound, then i just stopped seeing it or seeing any signs from it, not seen or heard anything for a couple of months now.
Either way, it sounds like it worked out. Very good!
Just to be clear, your math on the dB was not 100% correct. It's not added to the ambient sound... In this case, your room was abut 35 dB (noise floor) and you had a device produce 75 dB. It's not additive i.e. 75-35 = 40, the device produced 75. If your noise floor was 10 dB, you still would have read 75 on the meter.
I see. Thanks!!
@@metaspencer great presentation anyway, it was very helpful!
Decimeters cannot detect ultrasonic sounds. If there was a moving part in that first one, and you put the detector right on top of it, it would register a noise.
Thanks for your efforts. I was always convinced that these gadgets were too good to be true and probably total BS. good to see a logical analysis with dB tester.

Diatomaceous Earth.
It’s cheap, it’s amazing, and it works like a charm.
I moved into an apartment building once that turned out to be infested with roaches. Horrible. Asked the landlord to pay for spraying (even though I didn’t really want to, because I don’t think spraying hormone disrupters, etc, is good for us either, especially women). But I got it done anyway, and it did nothing.

You're supposed to remove any food sources that might be available to there mice.... When there is plenty of food around the incentive for the mice to stay around outweighs the annoyance of the loud high pitch sound... Shit if I was getting fed, free heat, room and board but had to put up with some annoying sounds I'd probably stick around too...

@@metaspencer most of them are probably junk. I do know from experience, my parents tried them back when I was in my early teens when the new upstairs neighbors brought cockroaches.

that meter only works up to 8 khz ultra sound is around 40khz
the nights they didnt show they went to a buffet.
Would the decibel reader pick up the low electrical charge from the one you plug in? Maybe you think it's ultrasonic but in reality it's just the electrical buzz it's picking up instead.
One thing you should know.....1 noise making 60 db and add another device making 60db does not equal 120 db. It would be 60 db. So your first device was actually putting out the registered amount. The higher number only cancels the lower so if it were dead quiet the readings would still be the same. just sayin
You mean it would be 63db, not 60 db. Two identical sound sources do not result in the same decibel level as a single source.
Q. The one we just bought says it must be plugged x inches above the floor. It is like over 30”! And it says it must be plugged into a vertical outlet, upright… not a sideways outlet.
We’re in a small apt, and most of the outlets are only a foot above the floor.
Can anyone explain why it would not be all right to plug it into an outlet that is only a foot above ground? Thanks.

@@metaspencer Thank you for your quick, savvy response. Had we seen this video, we probably would not have bought them.
Thus far, the only thing that had worked is a live catch metal cage with a trigger. Mouse ventures in, finds treats on platform, and the door shuts. Then i take them outside to release them. Sigh.
I waa hoping the sound deterrent would work.
My daughter sent me a Riddex after suffering a very bad spider bite at our house. The decrease in spider webs was very noticeable. Also i found a mouse in the middle of my dining room so disoriented I was able to put a jar over top of him and take him outside,
Can I ask if your meter is omni directional. It seems as if you were getting a better signal when it was pointed at the device.
I think unidirectional ... not 100% sure though
Well, even if the sound was annoying it was still worth enduring it for a free meal.
If they are ultra sonic that would mean they are super high frequency right? Based on info for stereo systems.... low frequency is referred to as low on no directional, while high frequency is directional. So I wonder how effective ultra sonic emissions are if the are uni directional. Meaning if the sounds is dispersed almost straight out of the emitter, do they have to stand directly in the path to be deterred by it?
Why do I see different numbers than what you are saying? Is decibels what we need to measure for these, anyway?
good video to prove that no electronic devices keep the mice away, I found that the best solution is the glue traps
You've got that right. These electronic kitties just don't work
check the ones that push metal claw with a spring to break their neck or legs if you think this is the most cruel one

that meter will not read ultrasonic sound, you need a special designed meter for that. I dont know what it is reading maybe just the noise of the device, also you dont add decibels that way, what ever the meter reads that is the level the device is emitting.
got it
Sorry. Decibel readings are not directly additive.
So, for that first reading you did on the big unit, 75 decibels would be its output (minus 0.00034).
I knew a guy back in the '70s who claimed that he caused his neighbor to get rid of his never-ending-barking dog (one of those dogs that barks for sport and it doesn't bother the owner) by hooking up an aquarium pump to a dog whistle via a short length of tubing and setting the pump (in a hole) and whistle (at the surface but camouflaged) as close to the property line as he could.

Thank you for your post!!
geoh7777 I was looking for someone to comment on that. He definitely did not understand how the meters work.
Thank you for video. It is good that you use a sound meter to evaluate DB level of each device. As far as I know, a quite room is appr 20 DBs. Conversation is 45 DBs. Busy traffic noise is 70 DBs. So anything below 70 will be ok for humans.
However, since rats can normally hear ultrasound in its lifetime, so an additional amount of ultrasound produced from small device would be neglected.
Anyhow I have been using this device for 2 weeks, I observed the different. It works under my carport.
By the way, in your tests those with no signal or 5 DB should be broken circuit board.
what is the freq range of that meter? may be out of range
could be, but I was surprised to see that it picked up emissions from some of the devices
and as far as the mice are concerned, they don't seem to mind the ultrasonic devices one bit
it is most likely sweeping freq range. some near our hearing. i suspect the meter is for human range.
+William Backer ...interesting! I'll check the specs
William Backer it actually registered on the first one. I thought the same until he showed the first meter. maybe the mice are deaf.
No! I've bought and tried electronic devices and they continued to tear the sound deadening material under the vehicles hood and they just seems to walk by it and get the material they want. SO nope, they don't work.
"Manufacturers of ultrasonic pest repellers make claims that may be unsupported by scientific testing. In fact, more than 60 companies received warning letters from the FTC in 2001 stating that “efficacy claims about those products must be supported by scientific evidence." Two years later, one company was sued by the FTC for violating its warning." [INTERNACHI]
I'm not at all surprised. They seem like a scam in almost all cases, if not all
I say we all band together and submit complaints to the FTC and have them all brought up on charges
High frequencys are very directional opposite than low that are omnidirectional saying that it only will work depending in the direction if is diffused also will the decibels. In other words is like having a pointer laser trying to kill mouses.
I installed an ultrasonic pest repellent in the kitchen and discovered the roaches actually congregated around the darn thing like it had candy on it. Weird. Save your money.
Crazy! I’m not surprised
That will make it easier to kill them.
Here’s another suggestion, that I believe works like a charm!!
Order (or go buy at walmart, academy sports, dicks outdoors or whatever sporting goods store, or online) some Red Fox Urine (others have used Grey Wolf Urine, and some Coyote Urine, just depends what is available, cheap, and ensure that you select one for a critter that isn’t likely to live in your area so you aren’t “luring” one to your home!!) and it repels critters that are its prey (costs from $10-$20 for several ounces in a bottle or spray bottle, aka plenty for your purposes), as soon as they (mice, rate, raccoons, small to mid sized critters) smell the larger predator urine (and typically it gets dark enough as most are naturally nocturnal that they can hall buns), they evacuate where ever (your home, grarage, horse stable, etc.) in order to get away from whatever predator they smelled that might be around hunting and trying to eat them!
We used this solution when a raccoon decided to tear open a section and then hide under our porch outside and to ensure that it didn’t go under and stay under our house. Once applied, as soon as it got dark, that thing (the raccoon) could be heard ripped its way out and then it hauled you know what!, and never came back!!
You have to apply the urine to somethiing or directly to your house at the 4 corners (we did all 4 corners and then middle on outside our house along with our porch, so in 6 spots, 9 total so perhaps a bit of overkill??..LoL!!) the urine smells awful, and of course it fades with time and so must be reapplied regularly to continue to work. Also, you have to wait for a dry (non-rainy, non-wet day as water washes the scent away if applied on the outside of your house or if whatever you spray it on gets wet) day.There are various “scent keys” you can hang up that shouldn’t get wet if you hang them up off the ground or obviously where water or rain or water run off can not reach them (or get creative like we did as decribed below). Then reapply, it one week later, so 1x a week for 1 month. Then every 2 weeks, and then once a month, and repeat.
We decided to spray some onto tennis balls that we had driven nails into and we tied fishing line around the nail, so we could then easily attach the fishing line at one end to something on the side of the house. That way, we sprayed the tennis balls, tossed them under the house, and later we could easily retrieve the tennis balls by pulling on the string, and reapplying the spray and tossing them back under the house. Obviously, using plastic gloves, and definitely standing up wind!!
Also, you can spray the red fox, grey wolf, (large predator) urine onto cotton balls, and place around your yard or inside your garage or roof (it will stink!!), various sporting good stores, or walmart or online, etc. also sell “lure” scent traps for hunters, which are key/pin things that basically are or have cotton or cloth strips in a P or T shape and you can hang them whereever with string, the whole point is that “prey” are repelled by the smell of a large (in its eyes) “predator” moving in, so it immediately moves “out” as it doesn’t wish to be eaten. So, there ya go!...
Lastly, this isn’t a soultion for “inside” your home for obvious reasons. For the slow to comprehend, what I mean is that, because spraying animal urine in your house will make it stink to high heaven (even outside or under your house you’ll smell it to a point depending how thick your walls are or floor...aka mobile home verus a brick structure), and also, spraying animal urine inside your house isn’t exactly sanitary!...Trust me, the smell will drive you out before the grossness of it being unsanitary!!
This solution is safe for pets, although I’m not sure it they’ll be happy about it, but it definitely won’t harm them physically, because it is only smell/scent! And of course, other than the smell, and as long as you do not touch it, use plastic gloves and wash your hands immediately after applying it, etc.. it is safe for humans too!!
Let me know if you have as much success as we have had...(and what with, which type critter)...
Hopefully, this works for you too! Good Luck!
Wow! That’s quite a procedure... interesting!
Can I apply this pradator scent inside my two car garage? My two dogs live in the garage so will it drive them crazy? I'm having a mice problem because of the dog food. Can I get this scent on Ebay?
Ultrasonics have no effect on mice
Thank you for doing this video. My question is this, did you try it only one at a time? I know from producing music that when you have two soundwaves that are the same, they can actually cancel each other out. I am wondering if that is a possibilty. I have a rodent running around my walls, so I am looking for a solution. Did you find one yet?
I started out with one ... and it wasn't working. So I tried a few more. I suppose the cancellation is possible; you never know
@@metaspencer it'd better will footage that u try it one by one..since what we can see in here u only show the result with two devices operational at the same times.
If anyone wants to buy these, just message me. I'll lend my mom to you for a fee and she'll keep on nagging for hours and output more decibels than these devices.
I have one of those in my apartment. And you know the strange thing is ever since I installed it I can't find my PS-2 mouse.
hahahahaha! that's the best one I've heard yet. high-larious! :)

Thanks. Your reply made my day!
