Mice some how get into my attic almost every fall. So I keep a couple of snap traps up there and bait them with just a dab of peanut butter. But five days in a row now, the peanut butter has disappeared though the traps have not snapped. Yesterday I added a couple of glue traps right next to the snap traps but they still got the peanut butter without getting trapped. I have never had such difficulty catching a mouse!
