Moles are small (up to 6 inches long) gray to black mammals with fine velvety fur. They have slender, hairless snouts and inconspicuous eyes and ears. Their eyesight is poor, but they have superior senses of smell, touch, and hearing. The front feet are much larger than the hind feet and have long, trowel-like claws used for tunneling in the ground. Moles live in burrows made up of many interconnecting runways, usually about 6 to 8 inches underground. Some species also dig many shallow feeding runways only a few inches below ground, which produces ridges on the soil surface. These ridges are especially noticeable in lawns. Moles dig lateral tunnels to the surface, where they deposit surplus soil in volcano-shaped mounds. Moles seldom feed on plants but do eat slugs, earthworms, grubs, and other small insects. They damage plants by their tunneling, which uproots plants or loosens the soil around roots and causes them to dry out and die.
To prevent moles from damaging your lawn or garden use Ortho® Mole B Gon® Mole & Vole Repellent according to label instructions. Additional options include: Traps: Before placing traps in shallow tunnels, you must determine which tunnels are still active. Roll or tamp down the ridges. Those that are raised the following day are still active. Trapping in the main (deep) runways is usually more productive. To detect these deeper runways, probe between mounds with a rod. Poison baits and repellents are generally ineffective.
