At a local beek meeting last night, the speaker (Certified Master Bee Keeper) said that use of OAV while brood was present can kill the brood.
I have never heard of this, and don't really see this myself.
It was not clear if he was referring to dribble, or vaporization, since he said the best method when they are not in cluster is the dribble method, and while in cluster is to use a vaporizer.
Has anyone else experienced brood die off as a direct result of OA treatment.
