Place the V & L wind up mouse 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 wind-up 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 poisonous chemicals, thanks to this simple catch-and-release trap. V&L Wind-up can hold up to 10 mice in the catch bin.
