In some cases, moles push soil they have excavated from their deep runways into the shallow tunnels. Moles usually ridge up the surface of the soil, so their tunnels can be readily followed. Moles make their home burrows in high, dry spots, but they prefer to hunt in soil that is shaded, cool, moist, and populated by worms and grubs. This preference accounts for the mole's attraction to lawns and parks. In neglected orchards and natural woodlands, moles work undisturbed.
Moles commonly make denning areas under portions of large trees, buildings, or sidewalks.
The maze of passages that thread the soil provides protective cover and traffic for several species of small mammals. Voles, white-footed mice, and house mice live in and move through the mole runways, helping themselves to grains, seeds, and tubers. The mole, however, often gets blamed for damaging these plants. In doing so, they may damage plants by disrupting their roots. The teeth of a mole indicate the characteristic of its food and general behavior.
