cleaning up after mouse infestation

I take a sticky trap with a dab of peanut butter on it and put it in a plastic Skippy pb jar.
You have to bend the sticky trap to put it in, so the mice can't get stuck and drag it all over the place.
Put the cap on and toss it.

I also keep a small piece of 2x4 cedar from the kid's swingset in the car, best deterrent I have ever come across.
The key is to sand it once a year to keep it smelling, for some reason they hate it.
