This trap is a state-of-the-art mechanical trap that offers superior rat capture. The trap's interlocking teeth make rat escape virtually impossible. With this trap you'll get the perfect combination of trigger sensitivity and trap velocity - speed and responsiveness that ensure a successful and deadly capture. Easy to set and safer to use than traditional snap traps, the trap can be placed directly in a bait station, or tied to pipes or beams that rats may use as highways. A bait cup in the center of the trigger pedal makes it easy to add baits. Trap measures 5.50" x 2.55" x 3.16".
