I like perpetual mouse traps... Take a five gallon bucket, drill opposing holes two to three inches down the rim. Take a broom handle and cut it so that there are 3-4 inches sticking out either side. Then (here's the good part) use a paper towel roll and slide it over the broom handle inside the bucket. Spread a generous amount of peanut butter 2-3 inches wide in the center over the complete circumfrence of the roll. Put 3-4 inches of water in the bottom of the bucket. Take a 4 foot long 1x4 and dado a small lip about one inch down. Lean it on the bucket.

Now you have a mouse trap that only needs fresh peanut butter.

Takes a bit to get it up and running.... but all you have to do is reload peanut butter and pull out the carcasses.
