Until this past year, wax moths have never been more than a rare and minor
nuisance on my bee farm in Nova Scotia, Canada. However, this past fall I
had a very serious outbreak of wax moths,such that all of my several
thousand supers must be considered generally infested with all stages of
wax moth, egg , larva, pupa, and adult.

Can anyone tell me if the common wisdom is based in fact, that all stages
of wax moth are killed by freezing? If so, how and where do they overwinter
in a climate such as ours, with several months of freezing temperatures,
and with all supers held in unheated storage buildings? What should I do in
the spring to prevent reinfestation in the supers which don't go on hives
until July?

Thanks to all for any advice.
