Anyone who has ever said, “You’re making a mountain out of a mole hill” does not understand the frustration, angst and despair moles inflict on homeowners. These underground critters can turn a beautifully manicured lawn into something resembling a war zone, seemingly overnight.
Contrary to popular belief, moles are not rodents. They are insectivores. These small mammals spend their entire lives below the surface of the ground, tearing up suburban lawns and gardens in an endless quest for food.
While prevention methods generally never fully protect your lawn, there are a few steps you can take to make your yard more uninviting to moles.
Use insecticides to limit moles’ food supply. Bear in mind, however, that insecticides may reduce beneficial insects in your lawn and not all food sources are affected by pesticides.
Water your lawn less. Moles like soft, moist soil because it’s easier to dig through and it attracts grubs, worms and other food sources. A thorough watering once a week should be enough to keep your lawn healthy while limiting moles’ food sources.
Set up barriers. Since moles have trouble burrowing through dense soil, you can arrange rocks or dense, clay soil around gardens or other small spaces to a depth of two feet to help prevent moles from entering the area. Or, you can bury metal mesh hardware cloth two feet into the ground with 6 inches showing above ground to prevent moles from burrowing under or climbing into your garden.
