An Old Mousetrap
Here's an old timey mouse trap. Take a 5 gal bucket and fill it halfway full with water. Then make a "drum head" out of a paper grocery bag stretched over the top and held on with wire. Place a 1"x4" board from the floor up to the edge of the bucket to make an easy to get up ramp for the mice. Place some mouse goodies (cheese comes to mind) in the center of the drum head and turn out the lights and go to bed. Repeat nightly for a week after the first morning it's empty. Once the mice have discovered it they'll be practically screaming at you to turn out the lights and go to bed. After they've cleaned out the goodies every night for a week or so, then take a razor blade and cut an X in the top of the drum head. The next morning you'll awake to find the entire colony drowned in the bucket.
