Supplies needed: 4 wheel rolling dolly, supers you want to protect, moth crystals like you hang on a closet rod (active ingredient must start with the letter 'p'), two queen excluders, two pieces of aluminum house/window screen, two bottom boards, roll of blue painters tape and 2 empty supers. Step 1 freeze supers in a deep freezer. Step 2 set a rolling dolly on the floor, then a bottom board, then a queen excluder, then aluminum house screen, now stack frozen bug free supers almost as high as you can reach. Step 3 now place on top of your frozen supers one empty super, then a queen excluder, then house screen, then lay your moth crystals on top of the excluder, then an empty super, then set a bottom board on top of your stack. Step 4 run a strip of blue tape around all the joints between your supers to prevent moth intrusion. Step 5 Now wheel, remember it is on a dolly, the whole stack into a corner out of the way for winter storage. Store in your garage or storage building, not on dirt/gravel base due to moisture in the ground causing mildew on all your combs.
Why this method works? Supers are sanitized, mice can't eat through metal excluder, moth can't eat through aluminum screen, and having a bottom board top and bottom allows for natural air flow to prevent mildew in a lower humidity environment like garage in your house.
Just what works for me.
