    Default Ok, im going from treatment free to oxalic acid vapor treatment and need opinions!!

    After seeing what them red frisbees can do to a strong healthy hive, im going to do my best to help them along with the fight against VM and have decided to go with OAV as my method of treating. I have been searching on youtube and on here as well as good ol' google to find different methods and cost efficiency. I have come up with possibly buying the JB 200 from up in Canada, actually from the Island I lived on for a while as a kid!!

    Anyone with any experience with the tool please chime in!! Or if you have heard of something else that might be latest and greatest, let me know!!

    I would like to build one, but dont have the mechanical expertise in this area, although some of you have made some great OA vaporizers!!

    I plan on carrying a marine battery for the power source and will eventually be treating somewhere in the neighborhood of 20+ hives next year.

    Thank you very much for any input you have!!

    I used a JB this fall and worked great. Kills mites real good. Its built a bit cheapish but it works better than anything sold out there. Queens and brood don't die but mites fall. Three treatments and your good.

    I went from treatment free to oxalic acid and have no complaints. Had my bees 20 feet from another beekeeper's bees while we pollinated melons this summer. His hives were almost over run with varroa. He spends a couple dollars per hive treating, I spend pennies for the same results. I had 8 vapor trays made at a machine shop for cheap. Two car batteries hooked in parallel on a dolly and a solar panel to recharge them, I run 4 vaporizers, makes for almost as fast treatment times as when I help another beekeeper treat hives with apiguard. If you can't build it buy it.

    I've used both the JB 200 and the Varrox Vaporizers. Both of them will get the job done nicely. If you can save up a few extra bucks the Varrox is worth it. It's sturdier and better constructed.

    The marine battery should work fine for you. I use a small garden tractor battery and it gets me through 10-11 colonies and still has a good charge left.

    Also, please invest in a good respirator.

    I worked at a home made vaporizer this past summer. One design required some Stainless steel fittings. I never did come up with anything I liked. My next attempt will be something that slides into the entrance of the hive. In the end I would probably have saved money and gotten my bees treated better had I just bought a ready made vaporizer. But what fun is there in that.

    I did finally manage to get my bees treated using Hooka Coals and small aluminum cups. I did not like the top down path for the vapors though. They want to rise up and I think I would have gotten far more dust on the bees if the vaporizer was at the bottom of the hive.
    Stand for what you believe, even if you stand alone.

    Yes, I didn't mention that part, it is an absolute MUST. Also wear clothes that are on their last legs as the acid tends to chew up clothes quite quickly.

    If I remember right I went with either an NGK or Bosch self regulating type of glow plug. No clue on the part number, they've lasted long enough to treat 40-50 hives twice.

    I didn't do the do the dribble method because by the time my colonies are broodless the daytime temps are rarely over 40 F and night time temps -8 F and I don't want to take chances with wet bees, plus you can't do the treatment very often.
