We'd be playing Nintendo late and could hear them scurrying around in the kitchen. Upon inspection we saw a small hole in the drywall where they were escaping into, so here's what we did.

1. Take a hose from a vacuum cleaner
2. Put one end in the drywall hole
3. Hang the other end over a Home Depot bucket
4. Put cheese puffs in the bucket
5. Turn off the lights and go to bed

In the morning we had 19 mice jumping around in the bucket. We never saw a mouse in his house again.
