I grew up on a farm so I know what it's like to have mice.
In high school I used to have a friend stay over quite often. Since I only had a single bed and no guest room we'd pull the mattress off onto the floor. She never wanted to sleep on just the box springs so she'd take the mattress on the floor and I'd get the springs to sleep on--not at all comfortable. After the lights were out I'd gently scratch, scratch, scratch in the wall--little tiny scratches like a mouse nibbling. Finally she'd say, "I'm not sleeping on the floor if there's a mouse in this room. You get down here and I'll sleep on the springs." Being the good hostess that I was I'd always give into her and let her have the springs. LOL
