Hello All During a lecture on all varroa treatments recently, where I set out the advantages and disadvantages of the various treatments, my attention was drawn to the possibility that I left out a major disadvantage of Bayvarol. The disadvantage claimed was that Bayvarol damages drone fertility. The speaker said that this comment had been made to him by at least one American beekeeper in Gormanston either last year or the year before. I had heard of this possibility before, but I did not have sufficient data on it to claim it at a lecture. Any comments please?
