In your general experience for curiosity, at what temperatures is it considered to be safe to expose untreated comb in a garage or warehouse as far as 'wax moths' are concerned?
When temperatures are below freezing.

I have found that as long as I freeze comb and then transfer it directly into a tightly sealed stack of stored boxes, I don't have any trouble. I did that for a couple of years and never had a waxworm outbreak. I do put mothballs in the stacks over the winter now, but that's more to keep out mice than moths.
I freeze the comb, then put it in tightly sealed trash bags, then store it in the top of my garage. I don't worry about the temperature.
Wax moth issues are very climate dependent.
