Unless you are in a perpetually warm climate, wax moths this time of year should not be a big problem. There are more bee trees around than you might realize. Put out a saucer of honey in an area where you think there are no bees and see how many visitors you get.I know there's a danger of wax moths if you leave built up frames out there hoping a swarm will make it home. What if you used foundationless frames in there? You could always keep boxes out "just in case" without having to worry about other invaders - no?
I doubt there are more than a few beekeepers within a few miles of me, tho. Chances of a swarm happening my way are probably slim, unless it's my own.
Same hear I am afraid. Checked 4 "long term" bee trees and only one survived the winter. Not doing any better than the beeks I am sorry to report.I have caught a few, but I only set out a few traps a year. This year I may put out more than usual but I am not hoping for much as the winter took its toll on the bees around here and killed a bunch of hives, both managed and wild.
