Answer: If they have frozen the bulbs will be mushy. If they feel firm, they're probably okay. They need to be kept moderately cool and dry in storage, so a cardboard box, paper bag, a traditional mesh bag, or even pantyhose will all allow air circulation and discourage rot. In my experience they will only attract mice if the mice are already there. If there are already critters there, make a hanging bin for them out of metal screening or similar material to keep them out of the critters' reach.
