Perhaps I should add that I need these traps to protect comb. Wax moths do not bother our bees (scutellata) in their hives. But I breed queens, and at any given time I have any number of deep frames in rotation, while frames with grafted larvae are with the cell builders. The unprotected frames (stored in normal lidded furniture) contain pollen and honey. There are other things around, such as small hive beetles and a kind of honey cockroach, but those are stories for another day. Barry
