Tomcat kills with a simple snap. The Tomcat Mouse Snap Traps are the pesticide-free way to control mice in your home. This reusable trap is easy to use, easy to set, and safer to use around kids and pets (versus conventional wooden traps). You can rely on our trap to effectively kill mice for clean, no-touch disposal. To use, set by squeezing the back side of the trap. While baiting isn't required, the use of Tomcat Attractant Gel (sold separately) is recommended. Place a small pencil eraser-sized amount of attractant onto the back of the yellow trigger. Mice have a natural tendency to run along walls as they move from hiding to feeding, so we recommend placing traps facing the walls of rooms or cupboards where activity is suspected, such as kitchens, basements, or garages (droppings and oily marks along baseboards are a telltale sign of activity). Once the mouse has been caught, just squeeze the back of the trap-your hands never touch the mouse! Now it's set and ready to be used again. This bundle includes 4 Tomcat Mouse Snap Traps.
