I've stored supers that way on occasion, and know beekeepers who do it regularly. No ill effects that I've seen.
Good to know that.
I've also opened them up in the spring to find that the queen has gone up thru the hole in the inner cover and begun laying in those stored supers!
DOH! Maybe putting screen mesh over the hole would be a solution to that. Wouldn't have to be anything elaborate.
If I tried to pull that off in my climate I'm afraid I'd be an SHB and wax moth keeper instead of a beekeeper.
Wax moths were my main concern when I did this. However when I put the supers on, it was right after I extracted so I think the bees cleaning up the supers could have kept the wax moths at bay. Maybe maybe not. The SHB never really concerned me as they have really not been a problem where my hives are...I attribute that to the amount of sun they get. Probably 90% of the day they are in direct sunlight. Back to the wax moths, they are pretty well gonners after the first frost so I am sure that helps also.
Sometimes I wish that I lived a litle further north to take advantage of the cold like y'all but then I snap to my senses. I could never leave Texas again.
I feel that way about PA. I find it hard to see myself leaving. This place would be my paradise if it weren't for the stupid winters. But then again...I'd have wax moths in my supers if we didn't have those winters.
Ahh...another thought on the wax moths...I believe they won't attach the comb if the comb never had brood in them. My comb is good that way. So maybe
