The Trapper T-Rex Rat Trap is a state-of-the-art mechanical trap that offers superior rat capture. Patented interlocking teeth make rat escape virtually impossible. With T-Rex 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 T-Rex can be placed directly in a Protecta Rat 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 including Bell's new Provoke Rat Attractant. Manufacturers recommendation: Do NOT use peanut butter in traps as the oil in peanut butter can damage the trap.
