The best trap is the one you make yourself and is super easy to make, manage and dump. You do have to have a drill. Take a standard 5 gallon bucket, a small empty can and a hangar, and a small amount of peanut butter. Now, make the best trap in the world for nearly zero cost. Leave the handle on the bucket for easy handling. Midway between the handle attachments to the bucket, drill two small holes near the top opposite of each other. Cut a hanger to two inches longer than the length between the two holes. Take any small to medium, round, empty can and mark the exact center of the flat top and bottom. Drill two holes at your center marking just large enough for your wire to pass through. You are almost finished making the best mouse trap known to man. Thread the straight hanger through one side of the bucket, through the can and out the opposite side of the bucket. Bend the ends over to secure the wire and slide the can to the center. Smear a small layer of peanut butter around the circular can to create a rolling cylinder. You can add peanut butter as necessary to balance the "wheel" for perfect operation. You are ready to capture every mouse in the area like kids lining up for free cotton candy at a carnival ride!
Put abou 4 or 5 inches of water in the bottom (if freezing, use some antifreeze) and set in place at any convenient spot. Now place a ramp to one or both edges at the end of the wire. Any scrap of wood, stick, or pole will work. It will not be long before you have multiple swimmers. Wait a day or so and they will all be deceased.
This will hold literally dozens with no action required by you. Just dump the bucket before they get stinky, refill and leave to guard the area indefinitely.
The principal operation is simple. They cannot resist the peanut butter, climb the ramp, balance on the edge and the wire and try to reach or jump for the can which rolls like a log roller and takes them swimming. It is always set, and fortunately the activity does not tip off the crowd but instead draws them in with the activity.
Obviously this does not fix the entry problem, but provides a "permanent" destination for all of the attendees. Labels are optional as to my knowledge mice do not understand English.
