Great stuff Bob, you’re doing things that can make a difference in the industry.
@BobBinnie always seems to deliver this info at just the right time! Nathan, what would us small guys do without him???!!!
I second that, I took over a retiring beekeeper, although I don't have his hives I have been using the equipment, this information could save some bees!
Wow; 2 thumbs up for this one!For quite some time I’ve been frustrated that the only information the experts would share about EFB is gloom and doom: terribly contagious, incomplete response to antibiotics, and no consensus on how to manage it. None of the great UA-cam beekeepers seemed to talk about having EFB. Maybe they worry it would damage their reputation if they admitted they had foulbrood infection in their operation. Yet I know that anyone who manages a significant number of hives over enough years is definitely going to experience EFB. So thank you for letting us ordinary beekeepers out there know that it’s not the end of the world, and there’s something that can be done. And that even the most successful beekeepers can experience it!
Bob , I’ve been using the recipe ever since you and Chris shared it on your queen rearing series. I’m sold it’s helped my colonies greatly! I use it on every colony twice a year spring and as I treat for mites in Aug . I’ve also used it on a DFW colony and had great turn around. I can’t thank you enough for these tid bits you provide ! Just outstanding!
Hello Spring City. Could you share the exact recipe you use? And did you find it actually helped with varroa mites? Grateful.
@@bradgoliphant Essential Oil Recipe: mix well-
1 gallon canola oil
100 ml eucalyptus oil
100 mi camphor oil
100 mI tea tree oil
4 rolls of blue shop towels cut in
half will make 8 rolls of half sheets
and will soak up all liquid. Apply a
single half sheet per deep box. Not
to be used with honey supers on. As in bobs Video tid bits with Chris Warner
I agree, the use of antibiotics is a slippery slope. Thanks for sharing your insight and wisdom Bob.
I wish someone would read the text displayed in your videos. It would really help those of us who listen when we can't watch the video closely! It would also really help those people who are vision impaired!!
It was with great pleasure that I popped in your shop in Georgia on our journey through the eastern parts of the US. Being from Germany I thought you might be interested in where all the people come from to actually see your company but the moment this thought came to me, I realised there may have been hundreds before me who had done the same so I decided not to disturb you and your crew. Bought a couple of jars of honey instead to help your business thrive!
Thank you !
I have been looking forward to this video…postponed my feeding duties this morning to watch.
I am intrigued by the tea tree and camphor oil treatments. Nice to have alternatives to the antibiotics.
Thanks for passing on the research.
Nice job!
Dr. Mayer had the final talk at the conference and we were all so fascinated that even though it was going to run over time, we unanimously agreed to stay until the end. If your talk with Dr. Mayer is long, I think it would be good to leave it long.
I second that!
Love these tidbits of insight! Although I haven't seen any evidence of EFB, we'll definitely be incorporating this into our outfit!
Thank you, Mr. Binnie. Another tool for our Bees.
I have just completed 4 weeks using this and have great results.
Sunday morning coffee and European foul brood insights. Would seem life is one big experiment. 🎉
*Thx4share interesting content Bob* 👍🇺🇲
Congratulations! Thank you very much! Michael beekeeper from Roumania!
Ha Bob great video thanks for doing it for us. going to get these and keep on hand Have a blessed day
thanks. great to have ways of control that dont involve drugs
I'll have to keep this video in mind if I ever see cases of AFB or EFB in my area, thanks for taking the time show this video.
Good to have this info in the arsenal! Thanks Bob
Thank you for maken your fantastic video!
I think when the bees are motivated to clean out the damaged brood they can recover.
Thank you Bob for your innovative approach❤💖❤
Thanks for the information Bob, hopefully I’ll never need to use it but it’s written down and in the arsenal.
Thanks,great information ,tried it and it worked 100%.
Thank you Bob for taking the time again!
I know this is gonna help so many people, thx. Bob
Tea tree towel recipe
1 gallon canola oil
200 ml tea tree oil
200 ml eucalyptus oil
100 ml camphor oil
That recipe makes 220 treatments - I reduced it and need someone to double check my math for about 3.5 treatments - 2 oz canola oil, 3 ml of Tea Tree Oil, 3 ml of Eucalyptus and 1.5ml of Camphor. Does this sound correct? Thanks Bob for the informative videos!!
@@timgoodin42053
2.1195347 canola oil,
3.18 ml tee tree oil,

your math looks correct to me...If there are 220 treatments in the original recipe
@@timgoodin42053 yes
Yes
Never had any European Foulbrood and like you we don't want any either. Think that because of where we live (desert) it is not nearly as common as other areas. As always Thank You for another informative video!
Hi Bob!! Great seeing you in Clanton last week..!! I have one colony out of my 42 that appear to have EFB. Like those y’all showed , it is weak . I believe I will try this treatment just to gain some insight if there are future issues ..
Thanks for sharing Bob.
Wow Bob thankyou for sharing this information, this could be a beehive saver!
Thanks for the information very informative 🇦🇺👍🐝🍯
Fantastic info, Bob. I had quite a bit of early season trouble with EFB this year, so I’ll be trying your recipe next spring for sure.
Another great video !!
Bob thanks for what u do !
Another great vedio , thank you
Hello Bob I hope you are having a great weekend to relax a little. Thanks
Hi Kathy. I'm in Louisiana speaking at a bee convention and having a good time. Thanks.
Would have been interesting to see a mite count before and after to see if it had a difference
Try it and place something underneath your hive so you can see what's falling out.
This is promising. Beekeepers don't need negative publicity regarding the indiscriminate use of antibiotics. I would like to see a follow-up on these hives, i.e., were the benefits temporary or permanent.
Dr. Reed
Another veterinarian with honey bees
I'll be sure to show them again before winter.
Thank you for this!!! 10 days ago I found EFB in one of my hives. I used this remedy and today there is no sign of it in my hive. Was it this or is that I have had a minor flow start, or a combination of both I don't know. What I do know is it will get another shot if I run into EFB again. Thanks again for all you do.
Let me say this .your a great guy your knowledge sharing is truly amazing ,I am in Western Australia got this mite heading our way this type of information is a huge weight off my mind as I was extremely worried about Efb coming with the mite .we not have it I Western Australia. Thanks much appreciated Allan Morgan
Efb has been in australia since the 70s and has little to do with varroa.
@@apisincognito8173 W.A has never Had EFB and is not using antibiotics in treatment of any disease. Legally that is .thanks for info
I add a few drops of ti tree oil to every bucket of sugar water, and have never seen much in the way of foulbrood.
Same here as a preventative.

Good Morning Bob!
Good morning sir!
This is great information Bob! How often do you all add a probiotic?
Once a month is recommended.
Had a breakout acure this year and had to use antibiotics. Would like to experiment with the prebiotics if it happens again
Wish my bees had that small amount of propolis. Hard to move frames in mine. It’s everywhere.
Can you please come to Western Australia and do a talk on your knowledge more so about varroa controls or management. These guys here are fence sitting thanks Bob
I hope Australia can dodge most of the bullets that are coming. I wish I could help somehow.
@@bobbinnie9872 you already have my friend you share your knowledge I tip my hat to you sir thanks for sharing. You are truly a beautiful soul you give me and so many something to aspire too kind regards Allan
Hello Bob. Yesterday I noticed pupae on the landing board on one of my hives yesterday. I don't know if it is hygienic behavior or what. I'm going to do a hive inspection today.
Coming down your way on Wednesday October 4th.
1st year beekeeper here, and I suspect I may have EFB in one of my 2 hives. Can’t tell if EFB or Hygenic behavior and discoloration of brood is from traffic. I’ve requeened this week, but didn’t know what else to do. I’m extremely grateful for your videos. Thank you.
Along with these towels feeding thin syrup and probiotics will also help.
@bobbennie9872 , will you try to cycle these combs out of the operation?
It would be good if they were cycled out quicker than normal. We'll try to keep track of where they go. @@taylorboysoutdoors
Bob, did you do a mite wash on a any of those EFB colonies?
No, but in hindsight it would have been interesting to know.
Good morning Bob! Can you please write the name of probiotic you use for your bees . Thanks
SuperDFM.
Thanks!!
In my very early years of beekeeping with 10 hives I encountered European Foulbrood. I didn't know what it was exactly at the time. Fearing it was American Foulbrood and being so paranoid of how contagious it was and the spreading of it to my other colonies I did the unthinkable. I buried alive my 10 frame double deep boxes with bees still in them and with still a good population into the ground. To this day when I walk past the slightly depressed piece of ground, with grass growing on it, I still think and feel what a unfortunate mistake I made. 😢 🐝 On a happier note Pittsburgh Steelers or Las Vegas Raiders? Not much of a choice. Lol.
Good story but I don't know about the football. 😊
Great video do you clean your hive tools they can help in spreading the virus. Good luck 👍
It's true that tools, equipment and even your hands can spread it. We currently aren't doing anything to clean things up. I hope we won't have to go to disinfecting everything. I think we're OK but of course we're watching this very carefully.
I wish that I could send you some pics of the ti tree in full bloom, its simply gorgeous. It is right now at it's peak here in Australia. My local variety is called coastal ti tree, and they are everywhere.
How good is the honey flow?
@@bobbinnie9872manuka honey is produced from the teatree.
♥♥♥♥
Bob...... any update on your use of this video?
Nothing new. We're not currently seeing any EFB.
Thank you for the info!
How many treatments result from this recipe?
220.
I use tea tree in my sugar water
Thanks Bob. Invaluable. What were the results of treatment on the hive shown at the beginning of the video which you identified with EFB infection? Were essential oils, antibiotics and/or both used for treatment?
We're not using antibiotics at this time. In that colony we tried to requeen but it did not take so it didn't make it.
After taking the late summer honey from the bees do you think it’s ok to combine formic acid treatment with the above preventative treatment thus targeting both varroa and AFB/EFB and perhaps feeding them a sugar/water solution 1:1?
I'm not sure how that combination would interact together. Could be fine but I don't know.
Hi Bob hope you are well could you say if it was essential oil for the tee tree eucalyptus and champhore what a great result. Thanks for sharing.
Yes. I believe they definitely had an effect.
Bob, this is a question on a different topic. There's a lot of talk about mice getting into hives. How are you preventing this? I see you have most of your hives on the ground basically. My understanding is mice can't get into the hive if the opening is only 3/8" wide. Is this how you keep the bottom board? Very grateful for your videos. I'm in my second year.
That's correct. All of our entrances are 3/8 inch which the vast majority of mice cannot get in. It's one of the main reasons I like 3/8.
It should be treated with an antibiotic mixed with sugar
When you finish the examination, sterilize the tools used
This has been the traditional treatment for some time. But, EFB is beginning to show resistance to antibiotics in some areas of our country.
Yes, it must be treated every 10 days. This is a disease called European foulbrood, which causes the larvae to rot. All of these diseases come from Varroa. 😥
I have eight colonies. It would really help the many small beekeepers who watch your wonderful videos, if you would tell us how to make very small amounts of the treatment You are using. It's going to take some math to figure out the concentrations from one gallon of canola oil, 200 ml of tea tree oil, 200 ml of eucalyptus oil, and 100 ml of camphor oil. If I want to treat eight hives, how much do I need to make?
Here’s my calculations for a scaled down version of the recipe.
1/2 cup canola oil
6.25 ml (1.3 tsp) tea tree oil
6.25 ml (1.3 tsp) eucalyptus oil
3.0 ml (3/5 tsp) camphor oil
@@davidbarnes936 Thank you! Do you know:
1. How much of that liquid will be absorbed into half of a blue shop towel?
2. Can we use a regular paper towel, or, why is a blue shop towel the "standard" way to put it in a hive?
Regular paper towels can work. Blue shop towels are just a bit tougher and hold more liquid. Also the bees don't chew them up and remove them as easily.
Do you just mix it up with a spoon or do you need a blender
It's easy to mix.@@alanwiebelhaus8750
Will the queens pheromones be disguised by the essential oil scents?
It would be good to test several hives and see if the bees start raising new queens when the oils are added.
Although they don't begin building queen cells I'm not sure if there is any affect on pheromones.
I hope for an update on how this method may work for the established comb and the spores that are present therein. please consider this for next spring and let us know. My colonies have been hit hard with EFB and antibiotics seem to have a short efficacy without replacing old equipment with new... am I the only one with this experience?
You're not alone. Many beekeepers are experiencing EFB that is resistant to antibiotics. I think there is a growing problem on the horizon and I'm not done talking about it.
just curious, have you been able to inspect your infected colonies since making this video? do you have good results?@@bobbinnie9872
@bobbinnie9872 Any updates 9 months later? Did it come back to any/some/none of the colonies? Also did you share any equipment between from the EFB colonies with colonies that weren't showing EFB symptoms?
Another comment he said he planned on showing an update before winter.
Curious what might be underneath the hive and what the bees are cleaning out of the infected frames
We didn't notice any debris.
Bob, is the towel holding the maximum amount of mixture, or it is mildly squeezed out?
Wet to the touch when applied.
How often are you treating with the DFM?
About every three weeks at this time.
Txs for the info; what kind of camphore oil and eucalyptus oil is used? The chemotype?
All i know is that it's organic.
Bob, we just treated about 300 colonies using your oils recipe. You used 1 towel in each single. Ours were all double deeps so we put a towel both top & bottom. Did we we do right?
Although a single towel in a double would probably be good enough I don't think one on top and one in the middle will be a problem.
Can these oil pads be used when honey supers are on?
I wouldn't. It may mix with the honey slightly.
How much of the prepared oil do you put on the half shop towel?
I don't know the exact amount. we just soak them in it.
@@bobbinnie9872 Thanks!
This is the same recipe Chris Werner uses on his bees. Didn’t he share this with you several years ago?
Yes he did.
Please could you explain better for an european. I find 1 gallon (4 liters) for 500ml of essential oils too much essential oil. What do you mean by a gallon, is it 4 liters?
This can kill bees.
One gallon is close to four liters. We don't have a problem with this recipe and others I know also do not. It only seems to harm bees that are immediately under the towel when it is placed. @@anabelaramos8399
What is a good treatment for this disease
Some people use antibiotics like oxytetracycline and others use essential oils as shown here.
Bob,
When you do a batch of shop towels, how long are the towels not used and stored in a sealed bucket good for before they no longer will have an effect?
If frozen it should last a long time. If not I'm not really sure.
can I ask a question , Can you feed bees bananas ? does it cause issues , health wise
I've heard of people doing that but I've never tried it and don't know much about it.
I have tried bananas before and even this year , never had any issues but not sure about health issues, long term , I saw other videos on feeding bananas , its the reason I tried it , but saying that I'm not sure about it and like above would love some insight into it
Hi Bob: Since you prepared 220 of those half towels and only used a small quantity of them, what are your long term storage plans for the left overs? Dick Brickner
Hi Dick. Jesse was just explaining the recipe which in hindsight may have bee misleading. We have left over oil which should be fine if it is stored in a cool location.
@@bobbinnie9872Hi Bob! I have suspicions that I have AFB, although laboratory tests show negative (maybe it is a more severe state of sacbrood). I won't be able to get to the apiaries for the next 3 weeks. Would it be ok to use this method once there will be 1 to 2 frames of brood (we have winter) and 50 to 60 Fahrenheit temps? Although colonies are good to mediocre, I would like to make this treatment as a prophylactic. Thank you and your guys for the knowledge you spread around!
I believe it would be OK.@@andreimolodoi88
@@bobbinnie9872 For how many days should the towels stay in hives? Thank you Sir!
We leave them in for a week or two. @@andreimolodoi88
Essential oils are essential, good for varroa as well. But I find that there are many ml of oils.
How many liters is a galon for americans does anybody know?
3.79.
Bob, is this off from Weavers recipe from your FL series ? He said he used 1gal Canola, 100ml each of Eucalyptus, Tea Tree & Camphor but I believe he said it was for (mite, no ?) EDIT, it was for Beetles. Also, how long are you going to leave these on for ? Any Queen issues?
Chris's recipe at that time was 100ml, 100 and 100 but for EFB 100 more tea tree is added. Towels will be removed on the following visit which in this case will be two weeks. I'm not using this for mites.
@@bobbinnie9872 Thank you Bob, I went back to listen again to Werner and it was about the Small Hive Beetles he was referring to. Thank you for all your Videos as they are TRULY Helpful to everyone who will listen
Hey Bob, have you ever noticed that humidity effects your OAV treatment? I'm being told by a beekeeper I look up to that our humidity here on the coast makes OAV ineffective. Have you heard of this to be true?
I honestly don't know about that. I've not seen a problem personally but we may not be as humid as you are.
@@bobbinnie9872 yeah it could be the season too I didn’t ask when they were treating. Hope all is well and tell Selena I said hi. I’ll need her to show me all the cool stuff I can’t afford but will buy at the next con. ;)
How do we differentiate EFB from Parasitic Mite Syndrome since the symptoms are almost identical? Thx
Theyre not almost identical
not good, no pollen feed them
do you hgave problems with afb over there? How do you treat that? in germany we only treat with making swarms in new material.
I have not heard of any AFB in our area although I know some in our country do. Over here it is recommended to burn the hive. Shaking the bees on new equipment and perhaps requeening sounds good.
Love watching your videos Bob. You have a great team! Thanks for your time. Couple questions - when do you add probiotics and how often do you use(3 weeks you had mentioned) but is it while you don’t have supers on? Like that whole time? And would you use the towels at the same time?
Thanks for your time!
From a small Island in the Great Lakes Canada
Probiotics can be added any time and are recommended once a month. We've been averaging three weeks lately because that's when we are there. I don't think a week, one way or the other, matters much. I've been told that the towel treatment we just showed won't effect the probiotics.
Hello Bryan. I would like to help answer one of your questions, and it’s the one about the use of Super DFM by Strong Microbials. It’s what Bob uses and what I’ve been using now for over four years AND SWEAR BY IT! I truly believe it alone is one of the main reasons my hives thrive all years. And yes, it can and should be used with other treatments because it was designed to help improve the guts of the bees when faces with stressors. Once a month is the recommended dose and sprinkled on top of the frames. But once every three weeks is fine. But nothing shorter than that. All the best.
@@bradgoliphant Thank-You Sir
@@bobbinnie9872 Thanks Bob
I’m going to try this!
Bob, do you have any alternative treatments for nosema?
Sorry no. We usually don't see that in our region.
Maybe I missed it, but how much of the mixture are you putting on the 1/2 shop towel? Or are you saturating the whole roll in the oil mixture similar to OA/glycerin towel production (ala Randy Oliver)?
Also, what are you thoughts on combining this mixture with the OA/glycerin shop towel mixture for a 2-in-1 application against varroa and EFB? My initial thoughts would be that it would dilute the OA mixture too much and affect the efficacy of that treatment against varroa.
We are totally soaking the towel and apply it after it is done dripping. I wouldn't mix it with OA without knowing if there could be a toxic synergistic interaction. Some compounds don't work well together.
Do you do more than one treatment ???
We did a follow up in this case.
How do you get around the law? Here efb or afb means instant destruction and burning and burying of the whole hive and equipment. Perhaps the law makers are a little overzealous.
American Foulbrood in Nebraska, USA is to be burned with the exception of wood supers, bottom boards, top covers which may be scorched with fire very thoroughly. I don't trust scorching woodenware. It is much better to just burn it all.
European Foulbrood doesn't have any required treatment - as far as I know.
Colonies with EFB are not required to be burned in Georgia. AFB yes.
I don't have a foul brood problem, but I have had a chalk brood problem for years. Tea tree oil is antifungal, what are your thoughts on this recipe helping with chalk brood? I have been running the OA strips, have almost non-existent varoa, I wonder if this recipe could be added to those strips.
It should be OK as long as you don't use the OA at the same time.
How long after these inspections did it take for a good brood pattern to develope? Thanks!
A couple of weeks and some feed showed a marked improvement.
@@bobbinnie9872 Thank you!
I’ve used tea tree oil before and that seems readily available. Where can you buy good quality camphor oil?
