I get these spiders in my bathroom every year. I finally decided to look up what they were and was briefly horrified to hear about their agressive and necrotizing bites. Then I thought back to all the times they've accidentally gotten in my hair or down my shirt and nothing has happened and figured I had either mis-identified them or the tales of their horror were overstated.
You pretending to be an upset teacher over Wikipedia cracked me up.
If ANY spider got in my hair or down my shirt, I would die.

Got bitten in my home from them, while putting my socks on. The bite lasted for weeks, as well as the itchiness, and it did felt like some sort of necrosis at some point.
I keep three of these spiders, and I think they may have two kinds of venom (as has been documented in some scorpions). When I feed them smaller prey, the carcasses are what you'd expect from a spider - hollow husks. But when you give them larger prey, like a bluebottle spike, or a prey item they have to fight (I mistakenly gave the male a too-big mealworm that wrecked his nest), the exoskeletons end up with chemical burns.
I've actually been bitten by them a few times, put my arm down on one while playing cards once, then a couple times cleaning the basement. It was less painful than a bee sting, but the bite became a very itchy, raised, red welt. It cleared up within a day. I don't kill them. I move them to the back porch. They get rid of other bugs.
BTW I user to work in the ER. The necrosis from spider bites I've seen, generally isn't a spreading necrosis, rather localized to a small area at the site of the bite.
Same here. They occasionally come in to live on my windowsill plants during the warm-weather months and then occasionally go “strolling” at night. I was bitten in my sleep a few times when one wanted to snuggle and I just rolled over on it. It just resulted in a sore, raised, red welt for a day. I put some Cortaid cream on it, no big deal. I always called them “Yellow Garden Spiders” and put them and their “cute black footsies” outside instead of committing “spidercide” whenever I see one in the house. I’ve often seen them sitting on/inside flowers (like tulips) but I just thought they were hunting for tiny pollinators.

@@eternaldarkness3139 Nah, then you'd be overrun with other pests.
I've had exactly the same experiences with Yellow Sac spiders, and they're the only spiders in my house that bite me. I had one just chewing on my leg for apparently no good reason. No problem though, a welt, early burning and itchy for a day. I don't kill them either, I have plenty of other bugs in the house for them to work on. Pity they don't eat the fleas the cats bring in.
@@eternaldarkness3139very short-sighted reaction
Holy, you're a meticulous perfectionist, I loved that you tried to do your own observations and experiments, rummaged through literature and contacted other researchers. Solid stuff through and through.
I got tired of being afraid of spiders. Ignorance breeds fear, so I'm learning about them. Thank you for sharing this info!
When traveling last summer our RV picked up quite a few of these guys.
I’m with you on this and since I have been learning about them, I’m absolutely fascinated with jumping spiders. I hand feed them mealworms every day now on my backyard aluminum fence, lol. They are the only spiders I hold and let crawl on my hands since they don’t typically bite.
You should be scared of them. Just think about this, everybody's body reacts differently, and there a A LOT of dangerous spiders. Where do you live? Let's look at how many can put hurt on you in your area. Also, I know spidey lovers like to claim they are harmless, but there a lot of species that will LUNGE AT YOUR FACE. Remember just right in this video, this guy said, "They will COME OUT AT NIGHT, so when your most asleep, they are walking RIGHT NEAR YOU.
@@vision821k4 🕷️🕸️
I used to be extremely scared of bugs. One year We went camping and I decided to buy my son a kit for bug hunting to keep him busy. Well I never dreamed he would want me to go bug hunting with him. After we caught some lightning bugs and some snails, I found myself watching some bug videos. I found a guy in korea that makes UA-cam videos on raising different bugs. One of them was a praying mantis. I fell in love, and the rest is history. I now raise and breed tons of different species of Praying Mantis. I make videos of them and post them of Tiktok. I have had a couple of jumping spiders, but spiders still kinda of scare me a little. 😂 But I am working on that fear. I don't pick them up if they are not jumping spiders because a lot of spider bites are toxic to humans. But I am no longer waking my husband up to kill them. I will catch them in a container. Watch them a minute. Maybe give them a meal and let them go in a safe spot outside my home if it's poisonous. If it were a jumping spider, I would let it stay because they eat other bugs, and they are cute and safe to handle. That being said, if you continue to expose yourself, you will get over your fear. I pray you do! Have a blessed day.
@@hollygallapoo5812 Praying Mantis can bite and they hurt a lot more than any damn evil spider.
You had me at "cute black toesies". Ms YellowSac now has a spooky story for the kids about the time she battled a Cheese Monster.
I love imagining this now.
Hahaha!
@@travismcenery2919
I wonder if any other things besides your cheese & some unfortunate guinea pigs were ever used?
You mentioned these things have a sense of smell & besides the cheese being much larger, it had to've given off an odor?
Maybe a different cheese or something? (Grape maybe held on a toothpick?)
I wonder if that piece of cheese imparts immunity against the venom if consumed.
🤣🤣🤣love it
As a former landscaper, I used to encounter these guys all the time. I was only ever bitten one time and that was because it got trapped in my glove where it is loose around the wrist.
All that happened was the bite area turned into a pustule that was moderately painful if it was disturbed. Within a week, it was cleared with no other issues. These spiders are not aggressive, and their venom is more of an irritant than anything. Still you need to wash the bite to prevent any sort of bacterial infection.
Did you gain any powers?
@@ArtholosYes, he has this strange sack between his legs.
I have to disagree with your view on their aggressive behavior. I was bitten once on the back of the wrist. No provocation. It got on my arm via my shirt, crawled down my arm and randomly bit me.
It’s the only time a spider bit me unprovoked.
I never expected to be up at 2am watching a man harass spiders with cheese on a stick, but I'm glad I'm here
Same here 7 months later, 2:38 am
I'm so glad that this popped up in my sidebar recommendations! I saw the title/thumbnail and clicked because I definitely think of these guys as little "friends". I honestly didn't know about their supposed necrotic bite (but loved hearing you discuss the source of that info and the work showing it to be false). These little guys have been fairly common in all the houses I've lived in here in Southern Ontario, and observing them over the years has only made them more endearing to me. The way they wave their forelimbs around while moving, their little sleeping bags? Pretty cute in my opinion!
I recently had one scuttle across the kitchen counter and onto the cutting board I was chopping vegetables on to drink from the little puddle of water left from the potatoes I'd just washed and cut up. I tried relocating the little guy to another corner of the counter, but it was very insistent on the potato water and I ended up ceding that corner of the cutting board to it. It stayed there, daintily drinking water and cleaning it's feet for a few minutes while I finished prepping vegetables.
Aww, how adorable ☺. That was such a nice little story you told. You have a wonderful gift of the written word!
What a lovely thing to do! I feel sorry for any that are over wintering because I worry they'll starve. I like to feed insects to spiders if I can, but without a web, I had no idea how to do that, or what these ones would eat. So with the info about the plants in the video, and your experience, I will have to experiment and see how it goes. I'm usually awake for much of the night and so I am very aware of any in the same room with me. I rarely find them, but when I first moved in, there were more of them. They have been in every home I've ever lived in, even the college dormitories out of state. I never thought they were a bother, glad I never heard the myth.
Aww..😇
Thanks for sharing - I was bitten by one of these, my only spider bite that I knew what it was...I tried to scare it off with my barefoot toe. Bad idea, it bit me. Stung no more than yellow jacket, no necrosis, slight swelling that subsided with the pain over the next 30 minutes or so. Within an hour all symptoms were gone. Still a healthy respect though.
Yup - just because the bite isn't serious doesn't mean it doesn't suck. I don't prod these spiders with bare fingers very often.
Lucky, only spiders I've been bitten by are 2 brown recluses and a black widow, would have preferred a yellow sack if I had to choose.
@@tarrantwolf That sucks, despite the discomfort I'll take the yellow over those any day.
A bite can become a problem from any spider or insect if you develope cellulitis- a common bacterial skin infection that causes redness, swelling, and pain in the infected area of the skin. If untreated, it can spread and cause serious health problems.
Did you wash your foot before sticking it in the spiders face? He probably smelled your toe lint and just couldn't believe the audacity. You deserved it, clearly. Spider is still disgusted, I'm sure. Tells the tale in the spider bar to his spider mates.
The hairs on their feet are important for chemosensation and also climbing grip, so my nonacademic guess is that keeping the feets properly groomed is particularly important for active hunters who climb a lot.
You know, I hadn't thought of that. That's very plausible!
He might also have been drinking what little water his feet was picking up :)
(In addition to grooming, I mean!)
100 points from a bibologist for the correct answer.
I've had two bad encounters with white widows in Texas they look like small stones not even spiders until you get really close and they are nasty the bad but I got cause nerve pain for over a year
@@talec_arashi That's what I thought too!
For years now I’ve been trying to convince my parents not to be scared of spiders, and your videos have finally done the trick! Love the research, love the video-work, great stuff!! 🙂
I love the fact that you just don't glean information from wikipedia, but actually do research and display what you found in an easy well informing structured way. Kudos to you! Subscribed.
As someone who loves having spiders in and around the house, I love your rating/reviewing at the end. "If you like surprises but don't like messes, this is the spider for you! Very polite and tidy" it got a great giggle out of me because it sounds like how I would talk to my arachnophobic friends.
I'm so glad you made a video defending our little friends! I've been telling people for YEARS that the Yellow Sack Spiders are nothing to worry about.
i still dont want them in my house you furry
It was the “stupid cheese” for me!
😂
This was suggested me to at random and immediately I sang along "the spiders in my car!" because I used to get yellow sac spiders in a 00s Toyota I owned. One time one sat placidly on my shoulder while driving a teen sibling around, another time I *felt* one sling from my head onto the sun visor because I could detect the pull of the silk tether, it was that strong, never felt anything like it before or again, just amazing stuff! I had no idea about the misinformation of WHY these spiders took interest in cars and still believed it to be gasoline-related, so I LOVE I learned the truth from your video! I can't wait to watch more. I love spiders and often wrangle them out of the reach of family and coworkers who aren't as arachnid-apologist as I. I've even taught my mom to catch and release them herself because over the years she understands it's important to keep them alive.
The rock in water is BRILLIANT! And the example of surface tension, wow!
EDIT: the upper right text in the aggression test. 🤣
This was a fantastic dive into the the yellow sac spider! The dedication to accuracy is noticable throughout and the content is supported with simple yet effective editing. You've out done yourself, I look forward to any future content! Good luck growing the channel man!
Thanks so much for the feedback. I'm working on more!
Long-term certified arachnophobe here. Keep doing these! Lucas got me over my fear of jumping spiders, and since then, I've found that being able to identify spiders, knowing their behaviors, usefulness, and actual danger factor has been instrumental in me accepting these creatures, appreciating them, and I've even become somewhat fascinated by them. When I see a jumping spider on my house now, I'll stick out my hand and see if they'll hop onboard! I would have never imagined I would do such a thing. This is one of the best series I've seen in this regard. The one's that still give me the willies are what I call the "High-Speed Ground Hunter" variety.
Lucas is great. Glad I've been able to help, and I do intend to continue with more videos. Stay tuned!
Huntsman spiders are terrifying. I find tarantulas intimidating, but I don't run away on sight like I do with huntsman spiders.
Lmao they're so little, they're cute.
I've been scared to death of spiders my whole life. I've always loved snakes. I've got a ball python that is basically my dog. After I got her I became confused at all the people who were terrified to the point they'd kill her if she wandered into their yard. Then I fell into a loop of tarantula keeping videos
The end result is my neighbors hearing me scream stuff in the middle of the night chasing wolf spiders in my apartment with a jar like "goddammit, I'll let you live if you just stop". I can't sleep with them on the loose, but if I can get them out before they're getting away then they live
Had a wolf spider the size of a silver dollar at work. He was in the floor space I was installing. Instead of smashing i chased it down with a long piece of cardboard till it gave up and climbed on. Then I ran him outside
Jumping spiders are the only ones that ai will handle. One hung out with me for over an hour the other day. Seem very intelligent
That shot of the spider slowly swaying on the water as chill as can be was absolutely priceless, thank you.
A little yellow spider landed on my shoulder this morning while I was on my way to make coffee. She jumped off and repelled down to the ground and ran off, but not before I got a pic. Loved this video, I’ve learned a lot over my cup of coffee this morning!
VERIFIED BITE: My husband called this video to my attention ... LOVE your thorough approach!
One night in July of 2009, I felt a brief but severe, wasp-like 'sting' as I was dozing to sleep and had rolled over (probably crushing the spider), and in reaction smacked/brushed my hand across my arm at the sting site. I felt a very small, tiny little something and flung back the sheets and blankets, only to find a small yellowy spider (now dead) under the covers just there by me.
Concerned by the pain, and wanting to know what had bitten me, I collected the spider on a slip of paper from my nightstand and, after first immediately applying antibiotic to the site (which was still nastily painful), I went down to my computer to search out what it was.
It WAS indeed a yellow sac spider:
I used a magnifying glass to confirm to my own satisfaction that in addition to its pale translucent yellowy coloration, it had those 'little black toesies,' and all the more evident characteristics of a yellow sac spider. I put it into a small container and over the next day tried to find someone (a doctor, someone at the Denver Museum of Nature & Science, *anybody*) who might be interested in verifying my ID. I emailed a few pictures I'd taken of it to one staffer at the Denver Botanic Gardens willing to help, and he confirmed it was indeed a yellow sac spider. (Over the following years, we have repeatedly and persistently found them both within our house (once in a little cloud of actively hatching baby spiders that we frantically destroyed) and in the surrounding outdoors; we're VERY familiar with them by now.) At the time, I was just glad it was NOT a brown recluse.
The bite formed a very small 1/16th to 1/8th-inch wide white pustule (note: despite washing, applying both Sting-Eze and a triple antibiotic immediately upon being bitten and continued reapplication of antibiotic for a week or two thereafter), the top of which after several days broke away, leaving a red open-flesh exposed wound about 1/4th-inch in diameter, surrounded by a narrow (1/8th-inch) red irritated circle of skin.
It was no big deal, and I don't know what qualifies as 'necrotizing,' but I CAN testify that the small, slightly sunken, exposed red wound did NOT spread at all, yet that it also would not heal and remained an open wound for at least 2 and (as I recall it) more like 3 weeks. S'all I've got for ya ... certainly for me it was *no more* than "very mildly necrotizing,' if even that ... but it sure wouldn't heal for quite a while. Maybe it depends on how much venom is delivered in the bite?
My grandfather (a professional horticulturist / entomolygist) taught me to appreciate spiders and insects on his apple orchard when I was a girl, and I love letting Daddy Long-Legs crawl on my hands and arms, but after that experience I *do* draw the line at not letting these little critters crawl around my home! ;}
Antibiotics aren't going to have any effect on spider venom. The transmission of bacteria from a bite, even when there's bacteria on their bites parts, is rare. Feel free to do it prophylactically, but don't expect it to help with the bite itself.
A 1/4" hemispherical wound that antibiotics didnt do anything to mitigate seems pretty sus
edit: shit i didnt mean to post that. ya prolly got bit by a spicy boi. it turned out fine and 98% of the time will continue to.
I love that you called them little black tootsies. It made my day.
ugh this is my worst fear! i've heard before of people rolling over in their sleep onto other venomous spiders accidentally and they wake up from being bitten. these guys are all over my house 😭😭
Sounds like an abscess
"Less wronger is more better" is quite possibly the best thing I've ever heard. I spent some time trying to defend spiders to a group of people just yesterday, I encouraged them to learn more about them because I think the fear most people have of spiders is due to a lack of knowledge. Thanks for this video, I can't wait to watch more of them!
Yup, I have a habit of telling people to learn about what scares them to understand them. I've been reading about spiders since I was a kid because of my sister's phobia, and my daughter's, to help them understand that most spiders are not out hunting was is too big for them. We are a buffet that would just go to waste! So, they only bite out of fear, or if they are trapped in your clothing as they are they are telling you to let them free. Would love to see a t-shirt with "Less wronger is more better". Would sell easily!
Alice Cooper and Vincent price the black widow song great song
100% agree! This needs to be on some merch to help fund the channel.
No people have a fear of spiders due to their biological instincts, knowing what they are doesn’t help
@@scrumpus8938 Put a comma in between "no" and "people".
Having loved spiders since I was a kid, and recently getting more interested in learning more about them, this was a perfect channel to discover! I'm looking forward to seeing more, you're doing a wonderful service for all our arachnid friends out there!
Glad you enjoyed it!
as a blind guy who doesn’t see spiders wandering around, it always amuses me about how spooked people who can see get around them.
@Derek Riemer How do you imagine shapes? Like when he describes the spiders parts how do you conceptualize it? Especially when it comes to tiny creatures that are harder to feel?
I love this channel! It has the perfect combination of relevant information, meticulous research and concise-engaging delivery that makes it perfect education!
I'm so glad you think so! Thank you so much!
Seconding this! I was just researching sac spiders earlier this week on behalf of a friend and this helped recap a lot of what I was reading.
Plus occasional doses of humor to keep it fresh! "...stupid *cheese*..."
Me too. Just discovered it a couple of days ago and it's awesome - can't wait for more videos.
I want to see more people doing their own research and citing their results! Bravo 👏 🎊 🎉
Despite living with these spiders for decades, I have never once heard that their bites "supposedly" cause necrosis. I thought it was common knowledge that they were relatively harmless unless provoked.
Excited for the future of this channel and a better understanding of our nightly protectors
I took a bite on my back was a shockingly sharp pain and that spot always itch's and it's been years but no necrosis
@@danielk8149 If it itches years later, then it probably killed some small fiber C-nerves in your skin at the location.
I have a scar about a pellet size on my left arm. The bite definitely caused necrosis.
I live in Quebec and I'm pretty sure I saw a few of these little creature where I live, including the "sleeping bags"... I was bitten maybe around 4-5 times since the last 20 years, always during sleeping. There is one thing that I find really weird, like he said these spiders are not especially aggressive and should only bite when being disturbed or threatened, but there was this one time, a few years ago, I woke up with one bite on my left arm, it really hurts but it's noting really serious, just a bit red and 2 small holes are visible... The next morning, again! I had a second bite right next to the previous one! Wtf! lol! There was also this other time when I woke up with the same kind of bite exactly in between of my eyes... I'm not hating these little spiders but there is something weird about them that makes me feel a bit uncomfortable!
Same, lived with them all my life. Been (unverified) bitten multiple times, no necrosis with them.
thank you so much for creating this channel! i love spiders but finding information on common species is often so difficult with misinformation everywhere you look. it makes me happy to see more appreciation for these creatures around. i've been fond of yellow sac spiders especially ever since i had one live in my bedroom for a while a few years back! i named her maple - she was a very polite roommate.
This is such a great idea for a channel! I'll be here for every new video!
A couple of days ago I picked up a spool of thread off my floor and to my surprise one of these buggers crawled out of the middle of the spool of thread. I promptly dropped the thread and ran away in fear. I am not scared of spiders usually and happily coexist with them but when one emerges from something that you are holding and not expecting to see a fast little spider crawl out of, oh my god, terrifying lol.
I’ve got these spiders in my home in southeastern Ontario, and have been bitten when one fell off my ceiling onto me on my bed. The bite resulted in a tiny red area that itched for a couple of days, no uncomfortable symptoms. Amazing that your video popped up after viewing one on volcanoes, but I now know all I need about the yellow sack spider. Been calling them yellow spiders for years. Thank you so much. Great content! 🇨🇦🖖🏻🇨🇦
Oh, that's a big relief. Thank you so much for the video!
This came across my recommended videos and I'm glad I took the time to watch it. Thank you for an entertaining and informative half hour.
Your aggression test, while small in sample, holds true. I catch these as food for my black widow, Andrew Garfield. If the male slips out of the tongs it runs away, the females have charged right up my arm though. They're the only ones that put up a fight against AG too. No fear. Thanks for all the info! This was wicked in depth!
I love that you named your black widow Andrew Garfield
Aw Gawd….. running up your arm 😱
@@bobberman4641 I love that he keeps a pet black widow.
I've noticed the same thing. I like to prod spiders in the house to test for aggression, and squish the ones that are. A sort of selective breeding, if you wish to look at it like that. Lol
@@Rafael_Fuchs so it seems you're a mass arachno-misogynist 😱
I can say anecdotally that they seem to make new sacs each night as my home has quite a few of them seemingly at all times since I live near a forest. I'm both a spider enthusiast yet still fairly arachnaphobic so I like to know where they are at any given time, these ones don't make it easy!
Your mention of the extrafloral nectaries may have actually answered why I have so many...I keep several passionfruit plants indoors and they have a pair of these nectar glands at the base of their leaves.
Also the spider vs cheese combat was both hilarious as well as a nice way to test the theory. I really can't wait to see what you create in the future. I would like to suggest funnel webbed grass spiders as a video, they are super ubiquitous, showy, lightning fast,, have very distinct webs and most people have seen them in their windows or lawns. Iirc they also possess the reflective layers in their eyes (just like wolfies) and would love to learn more.
Yeah, I'm definitely leaning toward the "new sac every night" idea, I just couldn't find any sources confirming that specifically. And yeah, I'd suspect that the plants you have don't so much attract them as just support their survival when they're spiderlings, so more survive. Also, there are a couple of funnel web weavers I'd like to cover, but I need to actually find a couple to photograph. When I lived on Vancouver Island, we had tons of Giant House Spiders, but I haven't seen one since moving to Nova Scotia. They're apparently here, just not in my house.
Grass spiders are really cool! I had a male for a roommate last fall. It was fun to watch him eat fruit flies. I gave him free range & he never bothered me or left his web until one day he just vanished!
@@travismcenery2919 Maybe see if any of your followers can help - or even researchers? This is the kind of thing most researchers will happily cough footage over for; it's exceptionally well done.
More videos please! This is the best spider info and amusing too!
WOW, what a GREAT video!!! This was amazing, thank you!
From the title of the video, to the information, the creator, the research, the humor. All of this was so perfectly executed, others could learn from you!
i was so sad when I finished watching your first two videos and saw there werent anymore, im super happy you made another :) these are very informative but not boring
Same! I looked around to find similar videos, and there wasn't!
I'm glad you're enjoying them!
There'll be more coming, but they take a while to research and produce. Stay tuned, though. ;)
@@travismcenery2919 Are there any in particular that interest you, or have a scary experience with? I remember when I lived out in Idaho for a short time, and one night I woke up to a male black widow walking along my arm. It felt exactly like a hair being dragged across my arm. Scared me quite a bit! I had heard that learning about spiders could help lessen your fear of them, so I started learning more about them after that, even gave a speech at uni about arachnophobia. Your videos are PERFECT for learning :)
6:27 with the absolutely perfect delivery of "... a screen" is one of the greatest moments in cinematic history, possibly ever.
Haha, thanks!
Excellent and thorough. Since I see these all the time, it’s nice to know more.
I live in an area where yellow sac spiders are common enough to have seen a few in my house, and it always made me real nervous to see them on the ceiling overhead (where it does seem like they prefer to be, unhelpfully for my nerves).
Knowing their bite isn't that significant, and learning some fun facts about them (tiny black toes!), puts me at ease. Thanks for sharing this information about a common house guest!
This is a fantastic idea for a video series and you're doing a wonderful job with it. Understanding these creatures will help ensure that my future interactions with them are informed and perhaps a little less scary
Thank you so much! I'm glad that you found the information comforting.
Great video as always! Thank you
Won me over. Love the content and structure of these videos!
I have ADHD/Autism as well as an on and off again relationship with spiders. Recently I’ve begun hyperfixating on them in an attempt to help lessen my anxiety around different spiders I see in/around my living space, and these videos are fucking AMAZING dude!!! I’ve already gotten more at ease and even more willing to interact/leave their webs/relocate them to better spaces!! Notifications 100% turned on, cant wait for the next vid lol
Want to feel more comfortable with spiders??? Do you like Ewoks? From Star Wars? I'm ADHD/Autistic also I used to have severe problems with Spiders. Until I ran across some pictures of Great Jumping Spiders. Look them up. I swear they are actually friggin adorable. Blew me away. Never really had the same intense irrational fears of spiders after that.

i used to be afraid and super creeped out by spiders... then i decided to study them and keep a black widow as a pet... i love most siders but the huntsman spider still freaks me out... its long eratic legs moving in a creepy ass way... only spider that freaks me out... jumping spiders are like cute puppies... widows are beautiful and precision killers..
@@nerdjournal yes, jumpers are adorable.
Ditto
I live in a Texas home out in the country & was attacked by a very aggressive spider. It was about the size with lighter coloration of a Wolf spider, but behaved differently, was thinner with larger fangs. I didn't give it a chance to bite me but it actually chased me for several feet, dodging furniture, rearing on it's back legs with it's front legs up. I managed to capture it and took several pictures of it. It's behaviour reminded me of those Funnel Spiders of Australia. I wish I had known of you and your channel as I would have loved to send it to someone for clarification. I still have the pictures of it if you would like one? Btw, I'm not exactly afraid of spiders but I do respect them. It was under my PC desk near where I keep my feet. I'd just gotten up to go get a snack when we saw each other.This particular spider frightened me because as soon realized I saw it, it attacked. Rather abnormal behaviour for a spider, I think.
oh gosh if a spider chased me like this I would be absolutely terrified, now I really want to know what it is
"It was under my PC desk near where I keep my feet." I can't stop laughing at the way you worded that statement. Makes me want to reply that "maybe you should find another place to keep your feet. Problem solved."
@@ericl2969 Or I could just remove my feet with a machete! Problem solved. ;~ ) I remember a time when my sister came across a mouse and she was hopping around trying to pick up both legs as high off the floor as possible only not at the same time. It was hilarious. Her knees were going higher than her head. Kind of like a spider dance only with two legs.
Thank you for making these! This is fantastic! I love the way you edit these videos and how you present the information about each spider~
Lots of research, simply structured, and good personality. Subscribed
I have 3 pea sized scars that were bites on my back. I can't 100% positively say they were yellow sack bites but those are and always have been the only spiders in my house and they are very common. I am someone who gets fairly nauseating almost flu or withdrawl like symptoms when I have a bite. The bites don't always get infected either the reason I believe they may have a very slight necrosis effect isn't the spiders themselves but bacteria on you, the sheets or the clothes you are wearing before or right after you were bit. It's not the spiders venom or fangs it's what gets into the wound the spider leaves which is why the necrosis is so rare and when you do get it the area that gets infected is so small.
there are likely other spiders in your house, you just don't see them because they're living in places where you don't look.
That's a possibility. A lot of things diagnosed as spider bites were actually staph infections. The problem is when people treat for spider venom when they should be treating for infection, which can actually make matters worse.
I will fully admit, too, when I got bit multiple times under my shirt (by what I have to assume was one of the billion yellow sac spiders in my place), I was very likely scratching in my sleep. Those things are itchy. I wonder if that damage is what gets mistaken for necrosis.
@@EaglesQuestions ...do you have room for furniture with all those yellow sac spiders running around?
Absolutely stellar presentation Bud. We've lived with these guys in all our rooms in Chicago & Sleepyville Wis. for 40 years, never been disturbed or bitten once. We've never killed any kind of spider indoors or out. I'm writing from my lap top desk where this season's 7 or 9 sacks are visible where the ceiling meets the wall 6-10' from my keyboard; we consider the yellow guys as very benign pets (once or twice in the last 3 years they've been on my desk or keyboard, no biggy, shoo-shoo, they're infinitely more cooperative than a cat or dog.) We've always had zero insects indoors, but in the yard we're rather concerned about carpenter & small red ant infestation of our old trees & exterior siding. PLEASE DON'T KILL SPIDERS PEOPLE! And stop paying Orkin to kill native birds via poisoning their food chain! Happy spider new year.
Thanks so much, and happy spider new year to you too!
Just a note that for West Coasters and others in America, "Bud" is diminutive. You can say that to some people and they'll take it as an insult, pretty much no matter how you package it. It's like you're talking to someone below your level of understanding, how a father talks to their son. Among strangers it can be very rude, especially if someone is doing you a favor or being particularly accommodating to you.
@@KAEFARIK whether or not bud is diminutive very much depends on tone in my experience, and tone really doesn’t carry over text.
Your research tracing is truly beautiful.
Thanks buddy, very informative and you're obviously passionate about this. Thumbs up.
So far you're 3/3 on spiders I see around the house and you're doing an incredible job explaining these spiders. A couple others I've seen regularly that I'd be fascinated to see more about are the American Grass Spider (Agelenopsis), Broad-faced Sac Spider (Trachelas Transquillus), and the Daring Jumping Spider (Phidippus audax). The first two I saw a lot of before replacing my basement windows - 70 year old wooden frames don't keep bugs out, especially at night if you have lights on. The jumping spider I see a lot in greenhouses. These all seem to be relatively common in virtually all of North America.
I have some kind of agelenopsis here. I've got my eyes open for trachelas tranquillus, and there are some jumping spiders outside (salticus scenicus, platycryptus undatus). Hope to cover them all eventually. Stay tuned!
@@travismcenery2919 You know it.
As someone who has lived with these guys all my life, they’re pretty chill. My mom and I always called them “banana butts” and they had an affinity for our kitchen sink (crappy back door to the countryside right next to it so there was an easy point of access). One time one was crawling next to me in my bed so I just flicked it to the other side of my room, it must have been a male looking back on it since it was pretty timid and didn’t bite me. Thanks for the videos, very educational! :)
My family had a nickname for those spiders too. We called them "booger green" spiders.
In our house we call them banana jacks!
Spiders tend to be very weak compared to most insects. Flicking it like that probably fatally injured it. Good 4U if you tolerate these but there are half a dozen other kinds which are more "fun to be around" and these are in my personal experience, likely to bite. Not dangerously venomous but I just don't like critters that are quick to bite when I could have others that are just as beneficial which never seem to. And are far more attractive. I'm very happy that all these chieracanthium types have disappeared from my home and have been replaced by more active and robust herpyllus ecclesiasticus, occasional crab spiders of two varieties and several others. I've never had the afore-mentioned type come rapelling down a line of silk and immediately bite me on landing on my arm. The nasty pallid sac spiders? Yes. I've never ever *seen* a herpyllus e. descending on a thread of silk at all. Just running around on any surface, always hunting. And they're very attractive. I wish they were a bit larger. The larger jumping spiders are the best! Those I adore. They can see you very well and know you're too big to eat and so are unlikely to bite you. You can play with them if they get on your screen by moving the mouse cursor around and they'll chase it . A diode LASER pointer dot too. You can often feed them by putting some bug on a flat surface near where their head is pointed if they're hungry. But the best favor you can do any spider in your house you want to survive/thrive is to use a little mister or even a very-well-cleaned-out perfume atomizer to provide them with a little artificial "dew" because the day night cycle where there's usually a little dew in the morning is their big natural source of water and they need it just like your dog cat, ferret or caged bird. Some rodents can fabricate water from some chemical trick they can do internally from eating seeds. But that's pretty rare.
Outdoors spiders can get a lot of hydration from a lot of insect prey. Is the interrior of your home that rife with insects? Probably not. So if you want some species of spider you can tolerate to thrive and survive water is key. You could even use one of those nasal saline inhalers after cleaning it out and putting a little distilled water in it. That's the sort of thing you can carry around in your pocket all the time so it's with you when you need it. The tops just pull off like a cork though it's not obvious by looking at 'em.
This video was randomly recommended to me this morning by UA-cam. Absolutely excellent! Loved all the spider info
Amazing video, thank you for being so thorough
I guess I’ve always been easy going with spiders, these little yellow fellows never bothered me either.
You sir are an entomology hero. Breaking knowledge down to mass understanding. Thank you.
Thank you! I love the in-depth information you are sharing. Great channel.
A wonderful channel, informative and entertaining! I eagerly look forward to more videos!!!
I have always been fascinated with spiders since a young age, and find them to be some of the most beautiful creatures on Earth. So it's nice to see someone providing information that isn't just fear-mongering and is actually well informed.
Cheers for the videos.
When I was living alone for a while, and being a bit of a night owl, I saw these guys quite often, alongside other spiders. However these ones were the ones that I saw more frequently than others, and they are much more unpredictable and common compared to the other types that were in my house.
They are also the spider that likes being near me more than the other types. It wasn't uncommon to see them be within 2-3 feet from me. Regularly when I was on my laptop they'd lower themselves down so they'd be about 1ft above my keyboard. Anytime I do dishes they liked being between my arms + dishes and my main body (Note, the back side of the sink had a place where ants would go that the yellow sac spider might be eating, but usually I could watch as some cellar spiders pick up and eat the tiny ants that tried to walk back there). This scared me when I was new to them, but they did it so often I just got used to it and they are pretty chill. However, when I used to use the big old boxy monitors, they loved running around that thing constantly, often spooking me by sprinting across the monitor doing laps. They probably thought there was a bug inside but couldn't figure out how to get to it.
Definitely the spider with the most stories for sure. I used to hate spiders, but growing up being bit by random bugs all the time, I was surprised they never bite me. Yellow sac spiders definitely mellowed me out when seeing any other type of spider, since most spiders I'm used to seeing aren't the super fast running types.
bro you get my sub just for the intro jingle alone- not to mention the awesome content!
Cannot thank you enough for this detailed instructive video.
YESSSS ANOTHER VIDEO!!! Just found you yesterday and your work is fantastic. Funny, educational, and enjoyable - even for this arachnophobe!
Thanks so much, I'm glad you're enjoying it!
Like yourself, I too just found his channel and love it!
Such good content, very informative, educational and hope others see this.
same here, I'm glad it's still going
Love these videos as someone who really appreciates life and finds it impossible to kill anything but is also deadly afraid of spiders. Most documentaries tend to really overdramatize arthropods in general and so this helps me learn about them and get more used to their presence without any of that bias and fearmongering that is so common in media.
Kill all spiders .
One of the best and informative videos ever. Keep up the great work.
You are making great videos here I was bummed to see you only had three so far, you definitely make great and sincere content thanks for the information!
I never ever expected to see macro video of a spider biting a piece of cheese, amazing! If you've got web sacs on your ceiling corners it also might not necessarily be these guys, I've found that some local species of jumping spider (~8mm body, mostly black, might be P. Audax) make similar little bungalows on occasion. Surprisingly I haven't seen any of these guys in my house since I know from past experience they're very common in the region, I don't know if they just don't show up at this altitude/temp band, or if the other species endemic to my house deal with them.
I was a little surprised she bit the cheese, too. I don't seem to have any jumping spiders inside the house, but in the warmer months I do have them outside. I see mostly platycryptus undatus and zebra jumpers here.
Yes I luv P audax n they do make similar little sleeping bags in the wild . I’ve found more of these guys in my house tho . I get so excited when I see a jumper in my house 😂
@@travismcenery2919 I luv platycriptus !! I noticed they move around unlike any other jumpers !!! The zebra jumpers are so tiny n inquisitive!!! I’m really enjoying your vids ❤
The ones in my house used to drink the milk left at the bottom of a cereal bowl on two occasions that I saw.
This channel is amazing! I'm a massive arachophobe, but learning about the common spiders in my house makes them a lot less scary. Thanks!
Glad you're enjoying it, and happy it's helping!
@@travismcenery2919 Would you happen to know any good databases / websites that I could use to learn about spiders in my specific area?
These videos are great! Can't wait to see more!
Fantastic video. This is the kind of channel that we need on UA-cam. New sub.
They're so cute! Thank you for your effort in filming them in such detail.
Glad you like them!
I remember waking up to a somewhat painful bite on my belly. Was swollen, and had 2 visible puncture wounds when viewed up close. Was a raised red area. Never was anything more than a minor annoyance and was gone within a day or two. I also remember seeing the sleeping sacks they make, though I always see empty ones. I'm assuming I was bitten by a yellow sac spider that, and now I know they're no big deal :) I've found every spider I've seen in my house on your channel, and now feel so much more comfortable living around them. Thank you for that! The info you provide here is a very good thing for all ears!
Thank you very much! We just found one of these in our house in Switzerland and your video was very helpful and interesting and could chill the whole family out about it. Lots of insight info, love it!
thank you for making such a quality video, this was genuinely so captivating
Thanks so much! Glad you liked it.
I'd wondered about this spider for years, not even knowing what the actual name of it was. It's nice to have all the information in one concise location, and having the information sources cited for further reading was particularly helpful. I'm glad UA-cam randomly tossed this in my recommended feed, and thank you for putting this together! I'm looking forward to checking out some of your other offerings.
Loved this video! I got bitten overnight a few days ago and found and captured the culprit the next day to identify the species. The bite marks looked pretty bad but nothing dangerous lol, I ended up taking a few pictures then taking it to the garage since it's cold out and didn't want her to die. Great vid! It was super educational.
Your Yellow Sac Spider-like willingness to leave the safety of the small, familiar web and hunt down sources (of information - not nutrition) has made this one of my favorite channels.
This channel has gotta be a new favorite. Your voice is incredibly nice to just zone out and listen to, especially if you're alt tabbing. I don't even have a spider problem, but I watched from beginning to end completely engaged. Keep up the good work!
Please keep these coming! I absolutely love your presentation, humor, and all! You are insanely informative. Thank you for making this vid
I am… soooo glad this channel exists.
I’ve been fascinated (semi obsessed lol) with arachnids my entire life - I lovvvve that you took the time to research and relay all of this information.
I can’t wait to see what you come up with next 💚🙌🏼
Thank you for what you do, Travis.
Thank you.
You are most welcome. Thank you for being here.
Way to be thorough and give plenty of information and references on your information. And props for being professional and staying on topic and still not being boring!
Enjoying these videos! Would be cool to see one on "wolf" spiders. When I lived at my parents home in their basement I would sometimes see one just chilling on my walls. Not exactly the stealthiest things lol. But they left me alone so I did the same.
Edit: after some quick googling, I'm thinking they may have been grass spiders based on the thinner body size. But I almost always saw them outside of webs so not sure.
Most likely grass spiders, those two can get mixed up pretty easily lol. I’d love to see a special on either one though, they’re each super beefy and cool looking!
Wolf Spiders & Tree Huntsman Spiders live in the base roots of trees or in dirt burrows. They hate sharing living space with humans & generally (99%) hate even barns or sheds with animals.
Common Grass Spiders are the 'spread-legged, gangly, fast-creeping' Spiders 'most likely' to be found co-habitating with humans in homes.
Common House Spider builds webs at mid-wall height & sits on their web to wait for bugs. (Has the large abdomen, I called them Fat Spiders as a kid)
Grass Spiders build webs at ankle-height & will usually be roaming around everywhere actively looking for bugs.
(3rd most common in my experience is a tie between Cellar Spiders 'Daddy-Log-Legs' & Yellow Sac Spiders)
(Most Spiders don't know what to think of humans. We're so big that they likely don't even perceive us as alive.
Like a 'moving mountain'. Jumping-Spiders DO have the 'nervous-system brains' for perceiving humans as 'something alive' though.
Scientists have proved that & are also using Jumping-Spider brains to model tiny super computers after, btw!)
I haven't watched this channel before, nor finished the video yet but still wanted to say I'm very happy this was recommended to me. This was absolutely interesting and educational. I have had these in my home before and thought (after googling, of course) that these were very dangerous. I developed a fear of spiders because of that. Thanks for the enlightenment. I plan to watch more of your videos as they're quite entertaining but also to help lessen my fear of spiders.
I absolutely love this channel! I'm so glad it appeared on my feed. Thanks for teaching us about these beautiful animals.
Glad you're enjoying it, thanks!
love this channel, keep going
I appreciate your high regard for sharing factual information. That is like a breath of fresh air in this day and age. TFS!
Glad you enjoyed it!
This is such a well-done, indepth look into this type of spider! Loving the in-depth, measured explanations and the total lack of "ewww it's so gross" or "AAAH KILL IT!" Nice to see these spiders treated with respect and care
Thanks so much for all the feedback, and I'm glad you enjoyed it!
I'm a big fan of your videos, I love learning more about these spiders and I appreciate your dedication to research and accuracy. I've already shared your channel with a few friends.
AWESOME tracing of sources. Love your role modeling
Thanks so much, I appreciate it!
Excellent video! Especially appreciate hearing about how you traced back the information to the original sources. Also, your sense of humor is just right! (I’ve had a pretty crummy day and this actually elicited a belly laugh from me.) Keep up the excellent work!
What a fascinating video. I would never have believed I would watch video about spiders that was over 1/2 an hour long, but I did and I thoroughly enjoyed it. I was very much intrigued with the information and especially the very well done photos and delivery. I'll be watching more of your videos with the hope they will be as interesting and watchable.
I knew a lot of this information already, but I love spiders and your channel produces that quality spider content I never knew I needed. I think people are severely misinformed in regard to a lot of spider-related topics, so I think it's great that you're making this series and that it's getting the visibility it deserves :)
I’m thoroughly impressed with the amount of research you put
Into this video.
Thank you for all of your effort in source citation and providing accurate information.
🤘🏻rock on man !
I have no idea how I stumbled across your channel, but I'm glad I did. I hope you keep this content up, it's both educational, interesting, and sometimes quite funny.
Love your style of production and presentation, real research! MORE PLEASE.....
Thanks, glad you like it! More is in the works.
This is my new favorite channel. Thank you for your amazing adherence to good research and presenting the truth about some much maligned lil critters. Spiders are amazing, delightful and beneficial animals. Thanks for taking the time to educate about them and how cool they are. Keep bringing it!!!
Thanks for your well researched thorough reported, delivered with levity, Travis. I’m writing this from a hospital room that I’m in recovering from surgery preformed to relieve an abscess from a Br own Recluse. They are plentiful in our area, Tennessee. He or she was probably taking shelter from the cold and I didn’t feel the bite when it occurred. I check footwear, however, this caught me off guard.
A nurse said they had a patient that was bitten by a Brown Recluses, on their eyeball. 😬
I enjoy your interesting channel, to which I was subscribed before this extremely unpleasant bite.
Brown recluses mostly try to avoid people, but when bites DO happen, yes, they can be really nasty.
The spider I've encountered the most in my entire life (Western NY State) and I knew so little about it!
Thanks so much for this and for the rest of your channel!
