Wax moths in dead hives?

[gpjohns]

Recently I inherited 6 hives. Wax moths had been in them. I see no signs of life in anything now and know that the hives have been empty for the last winter. I want to reuse the frames, so is there anything I should do to sterilize them?

It depends how bad is the damage. Usually any moth larvae are killed by low temperatures , like below 0 C deg. or in a refrigerator for 24 hours. Do not try to "Sterilize" . No need for that if you do not suspect other criteria , such as AFB evidence ,etc. The bees do the cleanup job quite expertly themselves and sterilize with their method.
If it should be too much of a mess. simply replace the foundation.
