You might want to remove the queen excluder from between the brood boxes and the honey super. As winter progresses, the bees will move upward to where the food is. If the queen can't get past the excluder, she'll be left behind as the cluster ascends, leaving her without the warmth of the other bees.

Very much appreciate the video, Northeast Ohio lost 85% of the hives this winter from mites despite treating in the fall

Thank you for making a video on this. Never have used fumigation on my hives but this is the first year that I am doing it.

Im so nervous to have to treat my bees but I’m having a mite issue in one of mine too. Ugh I was thinking of using OA so I saw your video. It puts my mind at easy a lil lol I don’t want to hurt them

Use the Cheapest version 10/15 dollars one, it makes no sense to have a temperature control once you connect it when cold it cannot pass the warning Temp until there is Oxalic Acid on it. Use also a water tank where to wash and cool each single use. Cover your dresses and your skin too with one of those paper full dresses (don't know the exact word). To make it completely harmless make sure mask is at least 2FP, better 3fp. Use the mask also later when opening hives the small Oxalic crystals will stay in the hive for long. Have lots of fun, but stay a little safer.

I think it will be better to vaporize after sunset when all the bees in the hive

Very clear and informative video. Thanks for taking the time to make it and share.

Did you ever do a follow-up video so we could see the results?? I've looked for one, but haven't been able to find a Part 2 to this video.

ONE CORRECTION to the video - text appears that say you can find "it" on eBay for half the price - I meant to write that you can find vaporizers on eBay for half the price, BUT, and this is a big BUT, they look like a much lower quality. This vaporizer is a really high quality product.

You can also vaporize with thyme oil

The printed squares on my sticky board came off when I wiped off the old oil

Mine takes 4 minutes to reach 157 c. Full battery = 13 volts. Ok there was no acid in the pan but the data is correct. An accurate laser thermometer was used , plus and minus .3 degC ! Each and every wand needs testing outside the hive with the oxalic acid and timed before application. Appropriate protection must be observed for any individual or animal near the fumes that are developed ! Take heed please.

I made one just like it that uses a diesel glow plug.

You can get a fogger for the same price and it treats at 100% kill rate and you can do 3 hives in less than 30 seconds 😊

Very interesting Did mine last night i thought do it at sunset where 99% were in the hive, My bees did not like that at all got zapped 3 times very annoyed at me learnt not to do it when most of the bees are in a big no no! my bees any other time very good just not last night hitting and trying to sting what ever they landed on my clothing. on the item can pick them up for about $20 do the exact thing heat up time it was quicker. Will add you can see you love your bees a lot with the way you put the boxes back seen other people just chuck there boxes on then later moan there bees were very stingy.

Good video straight and to the point

Straight to the point instructions, well done and thank you for sharing.

Perhaps a dumb question: do the bees avoid the heated surface? I'd hate to accidentally kill a bunch by touching them (especially the queen).

Thank you so much for your very helpful videos! It's great to have someone semi-local to me to follow (I'm in E TN.) Can you tell me why I should try to do the treatments with most or all of the bees inside the box? I just did this for the first time and wasn't able to do it at a time when they're all inside. Thanks again!

Try a ecoflow power pack. The presence of these parasites is alarming. I once saw a bee covered in parasites at least 30 years ago that landed, struggling then took off again and did not know what I was seeing. I wonder if preemptive treatment of other hives is a good idea.

Good video explanation thanks

Great Video! The NCSU hat in the background shows your intelligence. Go Pack!

I see you with the State hat in the background

Why scrape it in the front of the hive box, I would have done it 20-50 feet from the hive. Thanks for the heads up cheaper versions are available for the vaporizers. Would someone please do a comparative of differing vaporizers.

Interesting thanks for sharing.

What is the min temperature you can use oxalic Acid at?

U didn't get dead bees in the bowl where u put oxalic acid?

Good info

How many amperes should the battery be? Thank you.

Can honey treated with oxalic acid be consumed? I've already removed the supers, however just curious since you are treating yours while the supers are on. Thanks.

Thanks for posting. Do you think you may have put super back on to soon ?...... Just read a web page from dadant supply.... Says best to wait about 10 minutes. 😊 Says crystals form once vapors subside but recommends waiting a bit to put super back.

I used this one a 2 hive deep with slatted racks and one hive actually got fire and another time it burned the bottom of the frames. Tested in before hand and followed the instructions and the fire still occurred.

Very nice : Merry Christmas from Ireland :) !

Go, Pack!

The block is too big . too much mass to heat that is why it takes 7min to vaporize the acid .mine does it in one minute and a half.

Key Note, Walmart sells vaporizers for $31!!! Also, what type of battery do you use???

Hi, I was wondering. I do have screen bottoms for pest control on my hives. I could insert the Vaporizer through there and seal the front and what ever I have to seal from the back. This way I wont kill any bee that gets too close to the vaporizer that is hot. What are your thoughts on that? I also would be out of the bees way.

It must evaporate at the scale from 157 to 180 degrees celzius. Can you make sure with this evaporator that it does not overheat? If the heat is over 180 degrees, the oxalic acid produces the ultra toxic carbon monoxide that kills bees. Greetings from Slovenia.

Someone is using thrumbnails from your video on Amazon to sell vaporizers.

i just buyed 1 of those... but here is a question that is bugging me if the oxalic acid is toxic which it is will it not make the honey also toxic ?

Is this the only mite treatment you guys use, have you tried the mite away quick strips? We are in our first year of beekeeping, and would like to not treat for mites, but know all to well, it will only be a matter of time that there's a problem. Nice job on the videos. God bless

how many times a year do you do this treatment?

Was there another update video other then the no more varroa mites video?.

Mmmh, doesn't the vaporizer come with regular electric 110 Volt connection?

You are not using enough oxalic acid to treat your bees.

Was there a reason you chose oxalic acid over other types of treatment like formic acid mixed with honey?

Go Pack 🐺

Any first hand experience with the new Oxalika Pro vaporizer? kzfaq.info/get/bejne/pa94q8p_3d_Olo0.html

Hi! I am Serg. I am from Ukraine. I want to buy the same vaporizer, but i am worried a little bit about thickness of that aluminium pan for OA because i use a litle bit different hives. It has much smaller hive entrance on the bottom board. How much inches does that pan have? And one more question! Could you say voltage in your battery? Thanks in advanse P/S Sorry for my English.

I built my own. Less than $40 Canadian. Block of aluminum Drilled for the acid tub. Drilled and threaded for the handle drilled and threaded for two diesel engine glow plugs a chunk of 10 gauge extension cord and two clips for the battery. Just a quick test to see if it worked and a teaspoon was entirely sublimated in 4 minutes 28 seconds. I have to time correct dosage but i'm guessing same maybe a bit less. Reason I built one is Cause Canadian these units are costing over 100 dollars and that is a retarded price for a block of aluminum with a handle and a cord heated by a $20 or less glow plug, I built this for $40 bought it all except the cord for (Had a scrap cord already) Under $40. Me!! Myself! No mass quantity discounts. No assembly line. The one thing I have found to be very true about beekeeping is the prices for equipment are OBSCENE!!!! I am building much of my equipment if the time and material involved is worth it. Frames I buy unassembled because the time it takes to make them isn't worth it to make. But when a box is going for high 20 to low 30 dollar prices? I can pull my tools out of the garage and even sucking at wood work build 20 of those in a day easily. that's a 600 dollar day. Take off the materials and that's a 500 dollar day. one week of that and it paid for all my tools all the expenses and paid me a wage in a single week. I was trying to find a cheap extractor and was shocked. Found old antique 4 frame extractors rusted through and they still wanted $300.00. I know there is money in honey but a honey extractor with a rust hole as big as my fist is unrealistic and a gouge. After a whack of searching I bought a new stainless steel 2 frame for less then some folks are selling very cheap plastic ones for. In bees Search long and hard before you buy anything because there are folks ready to take advantage of the ignorant everywhere. Even my hives. I called around to small beekeepers and was quoted 260 dollars for a six frame nuc. Saw an ad from a commercial guy who was selling 10 frame production hives ready for supers for 270 dollars. 10 dollars more and ready to play. Most important advice I can give to beekeepers is to be patient and shop around big time. People are lined up to take advantage of the ignorant. In this trade it's a majority from what I see.
