Go to home depot and get a 5 gallon bucket and a piece of 1/2 pvc pipe. Drill holes on both sides of the bucket then slip the pipe in the holes. Screw or glue a 2 or 3" platform to the center of the pipe horizontal to the pipe. Put a dab of PB on the end of the platform. Now put 4 inches of water in the bucket. The disease ridden mouse will fall in the bucket and never be able to get out. The varmint will drown.
