<Roger Morse said all stages were killed in Ithaca and
every summer they migrated north from New Jersey and south. He said that is
why they were not typically seen until July.>
I would agree with that for Montana - except moths show up with returning
migratory beekeepers. I've seen occasional mild winter, where we got wax
moth survival in a metal container where boxes stored.
Overall, once we get rid of an infestation, we're good to go for several
years. My biggest source has been donated equipment, which I no longer
accept.
However, when I pulled a trailer full of hives to Maryland in 1995, I was
amazed to see wax moths flying into the entrances of the hives as I parked
and walked back to start to unload. That's a wax moth problem.
