I store both brood boxes and supers in my basement. I freeze them for a day and let them thaw out for a couple hours. After that is done, I double wrap them in garbage bags, alternating the opening and duct taping the little hole that is left after you draw it tight and tie it up. I've yet to have an issue with this. I've seen mouse poo on and around the bags, but I have yet to see them go in. Wax moths have yet to be an issue also. I've done this for 3 years now. The worse that's happened is the comb gets a bit moldy on occasion, but the bees clean it right out with no issues. If you use this method, use a bow knot to tie your bags so they are easy to open and not destroy the ties. Once you take the boxes and frames out the next year, you can reuse the bags for storage again or for their intended purpose.
