I never use to be as passionate about mouse removal until I had a very similar experience to IshtarsMom. The little suckers ate through my electrical wiring, brake line, and air hoses in the car!!! Lucky I didn't loose my life. Very expensive to repair.
I have traps strategically placed in the roof cavity (of the house) and in the garage. Yes - I have caught mice in the roof. If they chew the house wiring - they could burn down the house.
My traps are filled with peanut butter - just like you have done. It's very effective. Love the idea of luring them to the traps with pieces of batting. hehehe...
Honest - I'm not a nasty person - but when their actions can kill - it's a whole different game. My mouse problem was created by my neighbor (long story) and a very bad harvesting season for our region.
Currently have 2 large dogs - which are great at finding and killing rodents (well when they can get to them).
Good luck. Love to see the progress on your quilt repair.
