Victor Electronic Mouse Trap delivers a high-voltage shock to eliminate mice in less than 5 seconds. Killing up to 100 mice per set of batteries (4AA). The trap uses advanced smart circuit technology to sense when a rodent enters the units. Once the rodent is inside, the system delivers a humane, high-voltage shock to effectively kill the mouse. Rodents can then be dumped directly into the trash for no-touch, no-view mouse control. The trap features a built-in safety switch that automatically deactivates the trap whenever its door is open. Additionally, its unique tunnel design prevents kids and pets from reaching into the trap. Safe for use anywhere in the home. Victor Electronic Mouse Traps can be used for years to ensure effective mouse control.
