Re: Hive collapse and pests?
sorry about you losing your bees finesherb.
i agree that the 'dandruff' looking stuff in the cells in picture 1 is mite feces, and there is indeed lots of it.
i see some bees dead head first in some cells too, which usually indicates starvation.
the white stuff on the frame in picture 2 is mold.
the larvae do look like small hive beetle larvae.
was there any honey at all in the hive? if yes, and it had slime on it, those beetle larvae may have spoiled it to the point the bees could not use it anymore.
were you able to find the queen?
i think you are looking at a combination of several problems here.
