John, are you sure you don't still have mice problems?
I haven't seen mice in the house for quite a while. Maybe they don't like peanut butter any more. I suspect the wire itself is the issue because if I stomp on the floor a few times the wire gradually straightens itself out and creeps from the corners into the middle of the floor.
I am still seeing mice everywhere else though. I was driving into work this morning - cold, windy, maybe 6 inches of snow on the ground, but the roads were bare. Thought I saw something moving on the road ahead; sure enough a mouse was running across the road. I swerved so my tires didn't get him, and when I looked back he had turned around and was running back the way he came, much faster this time.
