The Nooski Revolutionary mouse and rat traps from Wilsons have consistently proven to be the most effective and humane means of killing rodents compared to traditional traps, the company has said. It is an excellent solution to tackle this ever increasing problem (rat population is currently estimated at 10 million in the UK according to the Daily Telegraph, 5th December 2017). Unlike conventional snap traps, the Nooski System cannot misfire and is 100% effective. No poison. No blood or mess. No more snapped fingers, and safe with children and pets. Kills quickly and humanely every time. Approved by Defra and Central Science Laboratories.
