When a mouse enters the electronic mouse killer and negotiates its way towards the bait,it reaches a point where it touches both killing plates and completes an electircal circuit, which kills the mouse instantly.

Four AA size batteries (not included) provide enough power for up to 50 kills.

Warning light signals when the batteries need replacing. Opening the device switches it off for safety.
Designed so no fingers, pens etc, can be inserted.

A warning light signals when the device has been activated, so that the remains can be removed and the trap reset.
