This video will not be well received by some beekeepers. We all want to have survivor stock that is naturally resistant, through genetic selection, to varroa destructor without any treatment - AKA "Treatment Free". I'm a personal fan of that approach.
YES! in response to those generous viewers who have asked how they can support my work, please follow this link: / 3494368
However, I have changed my tune this year as I have noticed the bees struggling with increasing varroa destructor numbers. I shared about, and installed three packages of Saskatraz honey bees this year and have been observing them explode in numbers and are demonstrating fantastic foraging and honey producing traits.
What they are not doing very well, is handling varroa mite loads on their own.
I consider it to be my responsibility as a beekeeper to observe closely and when appropriate, take corrective action when and where there is a problem.
There is a mite problem an in this video, I demonstrate how I am dealing with it.
The post treatment results (one treatment down, two more to go) have demonstrated immediate improvement in all colonies. The landing boards are clean and the bees are keeping up.
It's my opinion, that it's critical to intervene with varroa early, so the bees have time to recoup their losses while nectar and pollen resources continue in abundance. Recovery now, strengthens the colony and vastly improves their wintering survival.

Provap Instructions:
Connect the vaporizer to your 110 volt power source. It will take approximately 2 minutes to reach operating temperature. The red sequence readout will display 230 when ready.
In the white Teflon lids (recess side up) place the appropriate amount of OA. Do NOT pack the OA in the lid; rather place it loosely. Use one gram per brood chamber no matter the size be it mediums or deeps, eight or ten frame. Use a 1/8 gram on a nuc. One gram is almost ¼ teaspoon, so on a two brood chamber hive; you would use ½ a teaspoon. Invert the vaporizer. Take the white Teflon lid containing the OA and push it onto the bowl (be careful the vaporizer bowl is very HOT!) Place the still inverted vaporizer stem (with lid attached) into the drilled hole then turn the vaporizer right side up and tap the lid. The acid will fall into the bowl and start to vaporize.
This will cause the temperature to drop to approximately 210-215 then very quickly start to rise. When it again reaches 230, it is finished vaporizing and you can move on to the next hive. This will take approximately 20 seconds! You need to seal any openings during and 10 minutes after vaporization. It is not unusual to see the temperature rise above 230 to 250 during treatments. This is normal and well within tolerances.
The temperature is preset for 230 C. This is the correct setting for the bowl of this vaporizer. However, you can change it as follows:

I’m not sure why US requires honey supers to be removed prior to OAV treatment. There is no such requirement in Europe and there is OA in honey.

@FrederickDunn 5 лет назад

HI Steve! That is extremely interesting to me! I have been trying to get testing performed on honey here in the United States prior to and after oav exposure. Not one lab has a protocol for that test and many simply state that pre and post-treatment OA residue differences are almost "not measurable". Would you be willing to send me a link to an English explanation regarding OAV being permitted when honey supers are on? I am running into walls here in the U.S. when I try to get detailed information as to why we must isolate our honey supers. I look forward to learning more from you on the subject! Thank YOU.

They can carry enough sugar in their flight muscles to power an hour of flight but normally they carry enough sugar for 15 minutes of flight or about 5.5 km of distance. When bees feed on rich sugar solutions they can fly as fast as 29 km/h while a dilute solution results in slower flight speeds of 4 to 7 km/h When the blood sugar concentrations fall to 1 percent in the flight muscles, the forager can no longer fly and you will find the bee laying there tired wanting a drink.

Thanks for sharing. I always wondered what the bees did when such treatments were administered. Last month I placed formic acid pads and the stress they endured was terrible ... within a two week period only 10% of the bees remained, and quickly after the colony collapsed. I think they died because particularities to my horizontal hive made it impossible for the bees to naturally and properly vent the hive. I wouldn’t recommend filming the use of formic acid. Anyway, the filming of the bees as you applied a gas treatment was incredibly fascinating. Thanks!

@FrederickDunn 5 лет назад

Your story of the bees being killed off is all too familiar. I have no intention of using formic. Thank you for sharing that valuable information.

@naturessweetbees3033 2 года назад

I used the Pro Vap 110 as well and it is very effective. I credit the multiple treatments I did last fall is what saved my colonies throughout winter. The only difference I do from what you did Fred is a initiate the treatment through the front at the entrance hole. I do that mainly so that the pro-vac 110 device will rest easily on the landing board. This ensures that I do not break the delivery spout that you’re sticking the quarter inch hole at the back. I find the weight of the gun will damage the spout overtime if you do not hold onto it or support it somehow.

@FrederickDunn 2 года назад

Through the front, the initial "blast" directly impacts open brood during the warm season. Introducing it via the back, or upper part of the box greatly reduces that heat and the intense puff of oa. True, it's much better to support the unit, though it hasn't failed to date, it's a great idea to not let the copper tube support the entire unit. Thanks for sharing your ideas and use.

@disillusioned070 Месяц назад

I'm a first year beekeeper and just finished an OA vaporization treatment (middle August). Before the treatment my three hives were doing great. At the beginning of August I mite washed them and the mite count was at 3%. I smoked the entrances before vaporization and used 2 grams of OA in each hive because I have single deeps with one medium for my brood chambers and then a queen excluder isolating the supers above from the queen. I used a piece of cardboard as a barrier to isolate my supers from the OA. After the treatment I inspected my hives and had one missing queen with no eggs or larvae and all capped brood in the hive and one queen that was not laying. The other hive was doing great like nothing ever happened. I thought OA was supposed to be one of the least aggressive treatments for mites but two out my three hives took a drastic downturn after/during the treatment. I wondering if it was the OA or if it was just something that happened with the hive that I wasn't aware since I didn't inspect them during the treatment period.

All I can say is that I've not had that negative impact on my colonies. I'd continue investigating for other possible causes.

@rickl192 5 лет назад

I really enjoy how timely and relevant your video topics are. I am a first year beekeeper. I was told that in the first year I don’t need to worry about Verona mites and treatment this year would be unnecessary. I know everyone has different opinions regarding routine and technique but this sounds way too serious to hope I’m ok first year. I’ve only ever had dead bees on the landing board right after removing supers. Do you agree with the advice I was given?

@FrederickDunn 5 лет назад

HI Rick, thank you for this valuable question. There is some validation in the approach that the first year bees are installed IF they are a varroa resistant line, that they may not require any varroa or other potential infection interventions. You will hear other experienced beekeepers flatly state that "if you don't treat, ALL of your bees will be dead in less than three years". So many voices and words of beekeeping wisdom, each with their own experiences and approaches. Here is my personal philosophy on any pest management approach - learn about the pest and its life cycle - determine if the pest is present in damaging numbers - intervene if and when the bees are not coping on their own. My approach has always been, colonies that survive are good, colonies that don't make it just didn't have the level of resistance needed. I'm moderately altering course this year in order to see if my winter die-offs are due to the "cold" or the ever-present challenge of parasites inside the hive. Let's talk about the "first year don't need to worry" philosophy/advice - If you receive package bees, for example, I say treat them upon arrival as all of the bees are exposed as are the mites. Many beekeepers report receiving package bees with mite loads already on their bodies. If I capture a swarm, after the first week in the hive, I would "now" treat them with OAV before any of the brood is capped - again, that's because 100% of the bees and larvae are exposed to the treatment. I personally would not wait until losses are higher, or varroa numbers are at destructive density as they will then have much more to overcome. Remember that it's not just the varroa, but the diseases they are bringing with them. I think I will have to discuss this in greater detail in future FAQ videos as it's very important. If the varroa are present and growing in numbers, and your bees are not keeping those numbers at manageable levels, then I would not hesitate to assist those bees with an approved intervention method, no matter how long you've had the bees. I wish you well in your beekeeping journey, and thank you so much for watching! :)

@danskisbees7348 5 лет назад

I was told the samething my first year. The supplier said: "We've discussed it and we feel that the bees are relatively mite free." I didn't know any better, I didn't know about RU-vid beeks, I didn't have a mentor. Like Fred said, you have to test and go from there. You don't know whether or not your bees are robbing out someone else's failed colony, which has become a mite bomb.

@alteregos8949 5 лет назад

The temperature of the steam suddenly rushing into the colony probably annoys them more than the vapor. Kind of like getting splashed by cold water when you don’t expect it.

Dear Frederick Thank you for the reply. It's strange though it ages since I messaged you??????? We've been so disappointed this season compared with last year. No honey in the now. 3 Flow frames. The bees are hard at it and are working in the flow frames for over two months now but it's been a poor Summer and Spring was not musch better. I put one extra shallow super on two hives but it's not that as they are full of honey. The one that is the original hive we got 50lbs of honey from last year (40 out of the Flow frame and 10lbs in the Autumn) but this hive does not have 2 shallows on under the Flow frame but one. So they must be eating the honey due to the poor weather. = Wettest July for yonks! I hope your situation is much better than ours..... April swarms from the biggest colony even though they had space. The hose pipe had little effect on them and was only temporary...... My wife & I got plenty of stings many through our suits as well...... The new Queen seems to have settled them. Interesting that this is the hive that had a massive infestation of varroa when I bought them (1300 killed within a couple of months) (300 on the first drop) you said that's awful! The 'strips' have worked wonders. I know I know it's bending the rules but hey, it works! Perhapse I should not mention this success? best wishes & hope you have loads of lovely honey.

Good Morning Mr. Dunn! I’m a day late on this video, but what great information. Loved the Observation Hive treatment. Very cool to see how they react to the OAV. Question: The Beekeeper Association over here is telling everyone to use formic acid paddies first and then follow up with OAV a few weeks later... Formic seems to affect the bees where OAV does not... Can you think of a reason why both would be needed? Again, thanks for the incredible FAQ’s, I get so much out of them.

@FrederickDunn 5 лет назад

Dear Larry... because we've become friends and are brothers at arms... formic acid patties have killed many beekeeper's bees... the results are wide and varied with lots of horror stories about lost colonies. You will be fine if you use three OAV treatments 7 days apart... it's the only thing I currently endorse or would personally use on my own bees. I'm probably already getting kicked out of the treatment-free "club"... and that's also ok.

Hello Fred. I try to watch all your videos and just watched this one as per your reply to my message re another of your videos = 2021 latest I believe. I suppose they instinctively move away from any 'perceived' threat. Do we know how they 'feel' though. The saying, being cruel to be kind applies in this instance where we apply a noxious substance to treat the threat of the nasty Varroa mite. Eventually it is hoped that natural immunity will happen for bees. Those bees who realise if they are clean and vigilant and spot anything red on themselves or their relations =knock em off and munch em. pass the word --get em outa here! God forbid - a red under the bed?

@FrederickDunn Год назад

Genetics are definitely the long term goal. All we have regarding determining how the bees are impacted, is their behavior immediately after treatment. Since they return to business as usual right away, and the queen continues to lay eggs etc... an "assumption" is made that the impact is minimal regarding the bees and brood. Some other treatments result in instant responses that include dying bees, and often queen loss.

@RunningWithSauce Год назад

Hi Frederick! Long time no talk. Here learning from you once again!! Thank you. Are you still doing 3 treatments 7 days apart or has that changed?

Now days we take advantage of brood breaks and do fewer treatments. Whenever there is a swarm, split, or low brood, that's a great treatment window. If the colony is building rapidly, I have a queen holding method that creates the treatment opportunity - www.fredsfinefowl.com/queencagemethod.html

@MinnesotaBeekeeper 3 года назад

Respectfully may I suggest you update-edit this video. We now know that 3 treatments 7 days apart will not kill off most of the mites. 7 days apart allows the mites to get into brood being capped. Eggs to capping. What is now being suggested is 3 to 5 days on the outside for 6 to seven treatments. 2 grams per super and oddly enough we still don't know what it is about OA that kills the mites. Thank you Mr. Dunn.

@FrederickDunn 3 года назад

Hi Michael, 5-7 day intervals is what was approved. We track effectiveness with follow-up mite counts. When it comes to more treatment cycles or variable dosing beyond the approved treatment, I leave that to others. For example, a single treatment of OAV at the end of November, beginning of December can take out more than 90% of the phoretic mites when brood is at its lowest. Low brood periods can appear during periods of dearth which enhances the effectiveness of OAV. If the mite numbers don't come down when using the only approved OA which is Api-Bioxal, then it's time to use another approved treatment such as Formic Pro rather than simply modifying periodicity or dose. It really comes down to how far the mites have progressed before treatments are applied. I can't comply with your request to recommend going off-label. Others are certainly free to do so. I have to personally provide what's legal to do.

Questions about propolis: How do bees transport it? Does a forager go off just for propolis, or do they carry it back with their pollen and nectar? Thanks again for the great info.

@FrederickDunn 5 лет назад

Great question Keith! Propolis foragers just being in those resins and no pollen on the same trip. They are foraging specialists.

@dougstucki8253 3 года назад

Just FYI - I have read many places that the OA crystals stay in the hive for about 4 days. So any mites that emerge with hatching bees will die during that period. After that, the efficacy declines and mites that exit could possibly make their way into another cell right before it is capped. That means you should treat about every 4-5 days over a 24 day period when drones are still in production. If it is very late in the season and you are pretty sure the queen is no longer laying, then a 21 day treatment period would suffice. This will be more effective than only treating 3 times over 21 days, and as you said, the bees will be fine. So will the honey be if it is only for personal consumption.

My Saskatraz have pulled out a few pupae. But over all they are super strong. No varroa or pests.

All my Saskatraz colonies are my largest colonies. It is insane.

They definitely are booming in numbers - remember that often new colonies do well into the first winter and hold their own only to be overrun by varroa later in the year. Let me know how you're doing counts Carlos, I'd be very interested in the numbers. Also, the breeders for Saskatraz bees here in the U.S. are not controlling the mating stock, so we will probably see some variance in resistance.

@FrederickDunn 5 лет назад

HI Keith, the Queen generally is the layer and producer of all eggs in the hive. The workers decide how they develop and what they develop into with their highly specialized diet they assign. There are situations where a female worker begins to produce drone as they can only lay infertile eggs and all of those would be drones. It's a twisted diet-related world of wonder and the topic of much current research. It's the size of the cell and proteins fed during growth and development.

Frederick Dunn< I may be over thinking this but isn’t the purpose of treating (in this manner) is to deposit micro ox acid throughout the hive on virtually every surface, including the bee’s, wood frames and comb and if you isolate the super during treatment then when it is reintroduced the previously treated bee’s will contaminate the once isolated super. I’ve read that you only want to use a ox acid that is blessed by the “FDA” and I assume that is because of the residual contamination.

Hi John, I think you'll find that box to be just fine. Oxalic Levels that remain in future honey/wax/propolis, would be almost not discernable between treated and untreated hives. Oxalic acid is already present and introduced by the bees as they work the plants. I'm hitting dead ends regarding what the post-treatment levels are with exposed equipment and honey. The responses I've received suggest that the levels don't exist at high enough levels to make it "worth testing for". It's considered a soft organic acid that is derived from some of the healthiest greens we eat. Aside from not exposing honey for consumption, I'd feel comfortable sharing that your other hive components should be considered safe. Even with honey supers left on, it's difficult to find a variance in OA levels. The quest for knowledge in this area continues. Testing labs have no protocol for oxalis as it's not making the top 10 priority where honey is concerned.

Some were mentioning temps that would definitely change the fumes from Oxalic acid to formic acid and carbon monoxide, if Iv'e got the transformation correct due to overheating the oxalic acid. The main reason for my question is that over three days I've seen 2 minute grey insects walking about on the sticky sheet that I've now changed for vasilene instead. I wonder if these two insects are varroa. I killed one and put it in alcohol with a view to putting it under a microscope-----more expense! I thought the varroa were red not grey? is there a sure fire way to confirm the accuracy of what I'm looking at? I'm sorry to keep firing questions to you. Incidentally the heat treatment of varroa appeals to me and I'm building an insulated box that will bve controlled with a Chinese STC1000 controller. They are supposed to be accurate to .3 C. I've checked the temps with a good qual laser thermometer and indeed the device seems accurate and the differential also is .3 degC accurate. I'll be blowing air into the insulated box off our heating system radiator which is 50C.(why didn't I think of that before?) In any case the rad has a thermostatic valve which is quite controllable re the primary heat source. There's a bench top over the rad as well so It will work admirably. The bench top is always usually 25C. I measured the very accurate electric oven and while 4 frames would fit in it is either 40C or 45C which is either side of the appropriate temp which is advised as 41C to kill Varroa mites at all stages and especially in the capped brood frames. I was going to heat the bottom of this new hive but I've decided to go with your oxalic acid fumigation back end and winter to kill mites on the bees but if required heat frames earlier than the bees treatment when it's cooler.

You have one breed of bees that have good resistance to varoa and another breed that have poor resistance to varoa. Isn't that telling you that you have poor genetics that doesn't make economic sense to not only sustain but to propagate from. There is a fair bit of research now telling us that feral bees have much better disease resistance than managed hives and it is a much cheaper way of acquiring bees. All beekeepers should keep the opening sentence in the book -Beekeeping for all by Abbe Warre in mind. Apiculture or beekeeping is the art of managing bees with the intention of getting the maximum return from this work with the minimum of expenditure.

@FrederickDunn 5 лет назад

Hi Ben, thank you for commenting. We are continuing to monitor feral colonies of honeybees to see how they are surviving with our current pest and environmental challenges. The problem is that more than 90% of the feral colonies targeted for observation/study died out last winter. As a backyard beekeeper without commercial pressures, I am free to watch, learn, experiment and then of course, share the findings. If I were a bee-breeder, I would definitely have a different approach. For me, the "maximum return" is in knowledge, not monetary gain. Feral bees tend to swarm out often which results in breaks in varroa which is one way they are surviving. When a feral colony completely abandons a tree or other cavity, wax moths and other insect residents move in and consume the old comb - when the cavity is re-occupied by another feral colony, they seal it all up with propolis (antibacterial envelope) and then construct new comb and begin again. What seems to be continuous occupancy by feral bees often isn't "continuous". We have a lot to learn from feral bees and those studies will certainly continue. If someone is going into commercial beekeeping, the financial bottom line will certainly dictate their approach from hive construction to the genetics selected for maximum production. My viewers are largely backyard hobby beekeepers - most of the commercial keepers in my State are always treating their bees and most don't monitor for mites as that's "too time-consuming". I think the Saskatraz bees have many promising traits I will continue to see how they cope with our northern winters. Non-commercial beekeepers like myself, as with free-ranging chickens, are not guided by the financial bottom line - and will probably spend more than what may be gained financially. The rewards are a lifelong pursuit of bee knowledge.

@MrSydjf 5 лет назад

@@FrederickDunn I think you misjudge what most beginning beekeepers are prepared to spend on equipment. Its a mistake for beginning beekeepers to think they should buy flow hives, uneeded acid treatments trying to sustain colonies that are obviously failing and bees from different climates that are not adapted to their local environment. The bottom line is that for beekeeping to be popular everyone of limited financial means has to understand that beekeeping can have a good return on investment. That's why Abbe Warre called his book Beekeeping for All.

@masterbeekeeper30years18 5 лет назад

Ben K you seem to be completely out of touch here. Mr Dunn has demonstrated a thoughtful approach to intervention when it's required. How did you determine that the Saskatraz bees are failing? 90% of the commercial bees are requiring treatment. Where are you coming from?

@FrederickDunn 5 лет назад

@@MrSydjf HI Ben, I never tell people what to buy, I share information and leave it to them. In my first FlowHive video, I close it out by sharing how inexpensive Langstroth kits are. There are many ways to keep bees on a budget.

@@masterbeekeeper30years18 You obviously live in a different paradigm. The evidence is right before your eyes. Treatment free or natural beekeeping is being practiced around the world by amateurs and professionals without thinking they have to throw money at disease problems.

This is so sad to see this. How chemicals have destroyed our health and gods creatures

@FrederickDunn 5 лет назад

Please explain how these chemicals have destroyed your health and "God's Creatures"? If your family consumes a pound of carrots, you've ingested more oxalic acid than is in an entire treatment in a beehive. Please explain your position further? If the bees decline and die from varroa infestation and the diseases they have vectored, is that your preference. My mind is open and I'm very happy to have this discussion.

@BlessedBeJESUSCHRIST 5 лет назад

Let’s use your logic then. Allow the bees to collect oxalic acid on their own and consume it. I don’t force my family to eat a pound of carrots neither should you force bees

@BlessedBeJESUSCHRIST 5 лет назад

And yes it’s much better to allow the bees to die then to meddle with their health. There’s a reason why people are sicker than ever and bees the same. Chemicals, natural un natural have destroyed the health of food, life, everything. When you become dependent on treating a symptom instead of the root cause you will never have true health. The wisdom of man is foolishness to god

HI Bill, OAV has not shown to cause resistant bees. It's a naturally occuring acid that comes from plants and is already present in all bee comb. The levels of OA in the wax from treated and untreated hives are almost not measurable. It's a very different treatment.
