Re: Lost both hives
I don't think it is you going in that caused them to fled.
I think it is the SHB infestation that caused them to took off. In the
future do more frequent hive inspection to manage them better.
So why wait until the next season to reuse this clean up hive box? Just go
over to your father's house to make a hive split. At least the feral hive will
have a better chance at defending their home. Let them clean up whatever
usable comb are remaining.
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
