Charles do you know of cases where Apivar has failed and is known and proven? I have had a case where this maybe the case here and want to generate as much information on the failure as possible.
Afraid not, not a query I have asked or pursued, just acknowledging the potential. I do know a couple of package producers who do use Apivar.
I would suspect poor storage, but in the vide he mentions contact but mites didn't die. I am not a Apivar specialist, and am poorly quilified to reply, but as I understand it, Apivar is sub-lethal so contact with it even for hours would not expect to produce a dead mite. Quite differnt from OA or Formic which are contact killers.
