Self-resetting mouse trap that can be either lethal or no-kill: Drill holes on opposite sides of the bucket and in the two flat sides of the can. Insert the dowel through the bucket and can holes. Bait the trap by adding peanut butter to the beverage can and add a ramp for the mice to climb to the edge of the bucket. If you want to kill the mice add a few inches of water at the bottom. If you don't add the water the live mice won't be able to climb out and you can relocate them at your leisure.
Put a small piece of plastic wrap over the top of the bottle, then screw the cap back on. No leaks in the luggage!
