Its always very interesting to hear peoples different experiences from around the country. I think I have maybe seen 2 wax moth in getting on for 10 years here and never had a frame of comb damaged ever by them inside or outside the hive. Probably opened my fat gob too much there going into winter...
I seem to be in a hot spot for wax moth. Even really strong colonies don't escape them. I've had them in brood and super frames.
One year I stored supers containing frames in the shed, I ended up with a wax moth larvae infested shed. They burrowed their way into stored wooden garden furniture as well as the stored wooden hive parts and polynucs. That was the last time supers were stored indoors!
