treated 6 brood boxes of drawn comb with bt around 10 days ago. Sprayed them fairly heavy & made sure it had gone deep into the comb. Let them dry before storing them. set a box on top of an outer cover this morning getting ready to put it on a hive & when i lifted it there were 20 or so so larva on top of the inner cover. smushed them all & put all of those frames in the freezer. all of these frames were frozen for at least 4 days before i stored them & i had no problems until i treated them with the bt. so here is a barrage of questions?
-if some of these frames look clean what risk am i taking putting them on a strong hive?
-i do not have room in my freezer for all of these frames so if i stack them & put moth crystals on them will that kill these larva??
-i used the xertan bt using the recommended 2 tbsn per gallon of water. why would this happen??
-if any of these larva hit the ground could they survive or do they need to be in comb?
-could these be small hive beetle larva? do they ever get into stored comb?
