    I have only tried a shaker box once on a 4 box hive busting with bees and I was told that the queen was not there, quite frankly it was a pain in the rear as it was so slow. The bees from abox had...
  2. Re: Possible recommended OA vaporizer dosage changes

    Lee, that article was by Charles Linder. I seem to recollect that no matter where the OA was placed the mites died within 4 hours. The common wisdom at the time was that the OA killed the mites...
  3. Re: Possible recommended OA vaporizer dosage changes

    Can anybody Phd or whatever deny that oxalic acid crystals kill mites, It is my understanding that crystals on the mites feet or anywhere on the mites body leads to its death within hours. It is...
  4. Re: Possible recommended OA vaporizer dosage changes

    When I first started using OAV about 6 or 7 years ago I tried the 3 treatments 7 days apart and although many mites fell I still had high counts so I discounted the 3 treatment regimen and just...

    Re: Mites Won't Stop! Using OAV.

    OAV is no silver bullet as it only remains active within the hive for around 3 days. Doing 3 treatments every 7 days if you have a high mite count is much the same as putting Apistan or Apivar into...

    Re: OA Vapor & Dribble brood mortality

    Hey Msl, I get your message. Next year I can expect all my colonies to die as I have been using only OAV for mite control for the last 6 or 7 years, but never mind the good news is all the OAV...

    Re: OA Vapor & Dribble brood mortality

    In My opinion Randy Oliver is heavily biased against OAV, He once got a whiff of the vapor and is now convinced it is a dangerous material to work with. To make it even worse one of his B-L...
