Effective solution for pest control 1. Place the bait (such as peanut butter, chocolate, hazelnut spread) on the metal pedal of disabled trap using a toothpick, Q-tip or another tool to mask the human scent. 2. Place the armbar away from the trap. 3. To set the trap, carefully pull back the kill bar and hold it securely with your thumb. 4. With the other hand, place the armbar over the kill bar. Then lift the metal pedal slightly and insert the bent end of the armbar into the slot on the metal pedal. Slowly release pressure from the kill bar until the armbar has fully engaged and holds the kill bar securely. Take note the setting of the trigger sensitivity depends on the depth of the armbar insertion into the slot. DonÂ´t put fingers in the bait area of the activated trap. The trap’s spring force may cause injuries! 5. Carefully place the trap in areas of high rodent activity. The end of the trap with the baited pedal should be placed against the wall. After the rat is caught, dispose of the dead rodent by lifting it off the kill bar. We recommend using disposable gloves. The traps come in retail packaging in solid and eco-friendly carton box (see enclosed product image). The box containes 4 rat traps and user manual.
