This Pest-Stop wood-based, traditional rat trap is one of the most powerful on the market due to its strong spring. The treadle bait-station is based on the Little Nipper wooden mouse trap design. Bait is placed on the treadle, which is raised when the trap is set and the rat has to touch the treadle to reach the bait, triggering the trap. Quick and humane. Easy to use with full setting instructions included. PRCPSLNRB Pest-Stop Little Nipper Rat Trap is supplied in a box containing one trap.
