This brand-new mousetrap is simple to set and use, once baited, simply click the lever down to set. The mouse has to tread on a platform to reach the bait-well, which triggers the trap, meaning that the mouse cannot take the bait without triggering the trap. Simple to set and empty. No need to touch dead mice. Plastic construction makes for easy cleaning. Sold as a twin-pack, as it is advised to set more than 1 trap in an infested area to increase catch-rate. Quick and humane.
