When you see mole tunnels popping up in your yard, you'll want to have one of these on hand. The Victor® Mole Trap effectively kills moles without the use of chemicals or poisons. The plunger-style trap features weather-resistant spears that allow the trap to be used over and over again. Additionally, each trap is equipped with an easy to use design and safety pin to eliminate false firings. The trap comes fully assembled and with illustrated operating instructions on setting and placement. As the most effective mole trap on the market, you can rest assured that your yard is safe from the damaging effects of moles. Ideally, this mole trap should be placed into the tunnel with the tunnel portion beneath the trigger pan partially blocked. The trigger must rest on the blockage. It is because of this placement that traps works best for moles, since their natural instinct is to reopen the tunnel. In clearing the tunnel, they will push up on the trigger, releasing the powerful trap. Spring is the best time to trap moles because newly-made surface tunnels are easy to spot. However, moles can be trapped during any season except in very cold or dry weather.
