Moles are solitary creatures that are masters of tunneling. In fact, a single mole can create a tunnel system that can span an entire yard. While moles feed on worms and bugs, their constant digging also damages the root systems of plants, making them an unwanted pest. Thankfully, numerous traps are available to eliminate moles from a garden.
By far the most violent of the mole traps, a harpoon trap works by launching a sharp spike through the mole. This type of trap is best for sandy or clay soils, and quite effective at catching moles. These traps typically have very strong springs and require physical strength to set.
A scissor trap closes around the body of the mole, clamping it in place. Scissor traps are convenient for those who are unsure of the active mole tunnels, as the owner can check the trap without removing it from underground. Scissor traps are best for soils with a high amount of rock, as they are stationary and cannot be thrown out of alignment by rocks or debris. They are also good for placing in deeper laying tunnels.
The only humane trapping option, a pitfall trap allows for the live capture of moles. Pitfall traps are constructed by digging a hole into the bottom of one of the mole's tunnel and place a barrier, such as half of a soda bottle, into the hole, to prevent the mole from escaping or digging. If desiring a live capture, check the trap daily. This requires re-opening of the tunnel on a regular basis.
