Directions: 1) Place the bait (peanut butter) in the small compartment at one end, the side with the holes facing inward. So the mice are attracted by the smell and enter the trap. 2) Open the door at the other end, when the mouse moves to the opposite end where the bait is, the door will close quickly and automatically. 3) Once the mouse is captured, you can take the trap outside, open the food compartment and let the mouse go.
