Place the Ketch-All® trap 1½” to 2" away from and parallel to the wall, with either entrance hole facing the wall. The trap may also be placed with either end flush to the wall. The Ketch-All® uses a mouse’s own curiosity as bait. Once the mouse enters either side of the tunnel opening, the hair trigger activates the paddle wheel and the mouse is “spanked” into the cage compartment. Trapped mice attract other mice to the trap! Soon, the whole family of mice will be trapped with no bait, no mess, and no poisons! chemicals, thanks to this simple catch-and-release trap.
