I have a nuc that the bees froze in but it still has honey in it although its very dark honey. I didn't close the entrance and sure enough a mouse found a new home. It chewed up the bottom of the wax on plastic foundation but there is still honey at top of the frames. My question is can I let my girls rob it of its honey and then use the old wax for a swarm trap or do mice carry anything that would hurt the frames?
Your plan should be fine. I don't know about your area, but I sure had a lot more mice issues last winter than usual.
