How To Treat For Varroa Mites with a ProVap110 Oxalic Acid Vaporizer 

Tryed a lot of different devices. The provap ist the best i have found so far. Thx for the tip with the insulation and how you reload!

Bob, best wishes for a safe & enjoyable Thanksgiving! I was running 2 Pro Vap 110's by myself which did speed up treatments but still a lot of hassle measuring out OA charges. I debated trying to run a 3rd but that was just too much to juggle. I tried the Pro Vap EZ 110 and found it MUCH faster than running 2 110's and found that I can get about 70 shots of OA out of it before the nozzle begins to clog. Talking with Larry Welle @ Pro Vap, we tried raising the set temperature from 250 to 270 and the clogging issue improved. I later bumped it to 280 & added exhaust header wrap, and it works well. I see you go in through the entrance with your Pro Vap 110's. I keep an Imirie shim with an upper entrance for ventilation and spacing for food patties. Do you see any advantage or draw backs to discharging the OAV in the upper entrance as opposed to the lower entrance if available? On my double deeps, I discharge an OAV charge in both to ensure maximum coverage. Sure would appreciate your thoughts & opinion on this.

From this video, seems the procedure needs to include tapping the cap when the provap is inverted/inserted, to ensure the charge drops into the bowl at start. Notice at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ACqrvbNJC7w.html

I have tried several methods of OAV treatments. The best year I had wintering was the season I tried a burgess yard fogger. I run around 40 hives. The yard fogger crapped out from the acid eating the pump guts. Oxyvap takes me like an hour to do 5. The provap110 makes it easy again. I can treat a yard with 30 colonies in an hour including drive time getting there. Will be treating this afternoon. I think the yard fogger year was a fluke but it was so easy to treat that I was religious about it. Pick your method but the point is treat religiously. (Often) Another drawback to using the yard fogger is the price of that high octane everclear or gem. (198 proof)

What holds the wood entrance reducer in place while you treat? What keeps the ProVap upright?

Do you use anything besides OA for mite treatment throughout the year? If so, what and when?

Hi Bob, Will this method work with open mesh floors?

Is it safe to have syrup and pollen patties in the hive during treatment?

Bob, do you have wasp infestations in your colonies at any time of the year? If so, how do you deal with wasps?

Bob can you do O/A Vap with candy boards in place.

you setting the vap at 229 but I read 315 is optimum and above 370 is poisonous and will kill the bees. do you have any facts on this? I'm working on a tool that uses propane gas no electric and cost about 30 bucks to make. My temperature is running high so I'm trying to redesign the tool to get it in the correct range but there is not much information out there on this subject.

Can i get this machine in India

Gloves?????why dont wear.... good honey.....say too Greece.
