I checked out my hive box last night, good thing I did. there were wax moths in 1 of the 2 drawn combs. I vacuumed out the
box, inspected and cleaned the new frames. I removed the damaged potions of comb with the grubs and stuck both drawn frames into the freezer. That should kill everything. There were only about 6 grubs and a few empty adult shells.
They probably got into the box when it was at the swarm collectors place since he has lots of hive boxes there.
I am going to be moving my colony into this hive box tomorrow.... Good experience.
