A trap design that's stayed largely the same since 1897 has survived because it keeps working, not out of sentiment — and the Little Nipper's treadle mechanism is exactly that kind of design.

Bait sits on the treadle, which is raised when the trap is set; a mouse has to cross the treadle to reach the bait, and the slightest movement is enough to trigger it. Pest Stop still make it to that original pattern, and this pack gives you two traps rather than one, sized for mice at 40 x 100 x 20mm each.

• Twin pack: 2 traps
• Each trap measures 40mm (H) x 100mm (W) x 20mm (D)
• Original treadle design, first made in 1897
• Described by the maker as quick and humane with a high catch rate
• Instruction manual and setup video provided on the official page

On bait and placement. Pest Stop's own guidance on this listing covers the mechanism, not what to bait it with or where to put it — that detail comes from the instructions in the box or the manufacturer's own setup video, not from anything supplied here.

Who it's for: anyone dealing with mice at home who wants a proven mechanical trap design rather than poison, with two traps to cover more than one likely spot.
