Pest-Stop Trip Traps are a safe and friendly way to deal with unwanted house guests. This British-designed mouse trap has been especially developed to cause the least stress and no harm to mice when they are caught. The door drops automatically behind the mouse when it crosses the treadle to reach the bait, and the clear plastic body means you can see at a glance when you have caught something. Plentiful ventilation points reduce stress to caught mice. The traps are easy to bait and set, and each trap is provided with full instructions for use. Please note: Mice carry a variety of diseases, and should never be handled without protection. To minimise distress to captured mice, traps must be checked regularly (preferably every 2 hours), and should not be left overnight.PRCPSTTB Trip Trap humane mouse trap is supplied in a blister pack of 1.
