Be happy you are evicting the rodents on the ground. A number of
years ago I was happily flying along at 17,999 over the Collegiate
Range in central CO eating my ham & swiss sandwich when I felt
something crawling UNDER my leg. Seconds later that little bugger
crawled up on my leg. When he realized that he was about to get a
flying lesson (aero release out vent window) he popped back under my
leg and the seat cushion. I spent the next (seemed like hours) few
minutes feeling him squirm around under my butt.

My favorite anti-mouse solution is the Mouse Glue Board. Bate it up
with some peanut butter and tape it to a larger piece of cardboard.
Set it in you cockpit and wait to see what you get. The cardboard
keeps him from crapping all over your seat when he gets his front feet
stuck on the glue board. REMOVE MGB BEFORE FLIGHT!
