Live Capture Mouse Shrew Trap. Made of polypropylene, resistant to stains and odors. The Traps are easy to clean and can be reused or disposed of after mouse is caught. Place bait on the inside of the removable end cap. Place trap near a wall with trap door open. The smell of the bait will cascade from the unit, out the trap door and attract the mice. When the mouse enters the Trap it will cause the unit to tip - closing the door and trapping the mouse inside. To release, simply position the Trap over desired area, pull back on the closed trap door and let mouse slide out. Controls: Small Mice and Shrews.
