Will these work in the summer? I usually wait until fall and just lift off what I want, the local bears got a few and if I want some I better get them now. My hives are big 3 deep 2 meds with a heavy population and completely bearded, I think the 4 hives and 2 nucs the bears got joined the remaining 3??? Anyway I cant see them leaving the supers just because I put an escape board on. Any thoughts?
