One of the most powerful mousetraps available, the Advanced Mousetrap is also one of the easiest to use. Once baited, the trap is set by simply clicking the arm up into position. The mouse has to try and enter the bait-station to take the bait, which triggers the trap. Plastic and metal construction for easy cleaning. The mouse cannot take the bait without triggering the trap. Simple to set and empty, no need to touch dead mice. Sold as a twin-pack, as it is advised to set more than 1 trap in an infested location to increase catch-rate. Quick and humane.
