How Can I Get Rid of Moles?

by Evelyn Carlson

Overview

Moles are small burrowing animals that eat insects and worms. When they tunnel deep into the ground they cause little disturbance, but when their search for food brings them closer to the surface they can cause unsightly damage. In fact, if the damage is extensive it may undermine the health of plants and trees. Farmers, gardeners and homeowners who care about the appearance of their lawns often seek ways to eliminate these animals.
Avoiding the Myths

Home remedies and hearsay solutions for mole control abound. Common suggestions include placing ground glass, kitty litter, thorny rose vines, gum or cayenne pepper around the entry holes to burrows. None of these works because the moles have no inclination to eat or come in contact with these substances, so they simply dig another tunnel around them. Scare tactics and noise tactics, such as fireworks and ultrasonic devices, have never been demonstrated to be effective. One feasible possibility is to fumigate the holes with any variety of gaseous substances, but this is difficult since the tunnel network is usually extensive and deep, making it hard to close off or seal. One home remedy, planting marigolds around your flower gardens, is sometimes effective.

What Works Best?

According to the Internet Center for Wildlife Damage Management, certain fumigants, such as aluminum phosphide, can be used near the surface and are reported to be effective, at least to the point of driving the moles farther underground. (See Reference 1.) However, state regulations vary regarding pesticides and fumigants, so it is a good idea to check with the local conservation department before using them. The best solution is trapping. There are several different types of traps available that either choke or impale the moles. Any good garden-supply store carries a variety of traps, or one can be made easily by following readily available instructions. If the moles are few, live traps can be used, allowing for the relocation of the animals.
Other Considerations

For the most part, moles are not destructive in and of themselves. It is when their particular habits conflict with the needs and/or wishes of humans that they are considered "pests." This may be a major problem, as when they impede farming, or a more minor problem, as when they disfigure the front lawn. Moles serve some valuable purposes by eating many harmful, crop-destroying insects and by aerating the soil. If at all possible, and for humane reasons, you may choose to tamp down the mole hills as they appear and leave the moles in peace.
