Like Lburou said, also after i treat with BT i don't use moth crystals, but i don't store wet supers. Sounds like the wax moths found your supers again and probably laid eggs in them?i would think if you sprayed bt on them and let them dry before storing them that would kill any larva that hatched out. I have frames that are sprayed with bt that have a 2 in. to 4 in. streak were the wax moth larva traveled, but that's as far as they got before the bt killed them. Jack
