Re: OAV and hundreds of crawling/dying bees
They can if you simply removed the infected cap brood frames to a mite bee bomb nuc hive. No other
treatment is allowed.
Seriously, the queen and bees never recovered from the oav treatment. Right now is too late to find an answer.
If presented earlier I would give them a frame or 2 of bees and cap broods from another hive. It is too late now to
find the caused of it. Maybe oav or the mites still in there. A timeline with dates of the treatments would help.
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
