After freezing my medium honey frames last fall, I stored them in plastic bags and placed them in my garage. Took them out last week and found that wax moths have damaged one of them; both have some webbing.
After searching this site on handling wax moth damage, it appears that I can freeze the frames again and then put them on my strongest hive for the bees to finish cleaning up and repairing them.
Question: Since the first freezing didn't appear to kill the wax moths, how long should I freeze the frames this time?
