Moles will make their sleeping burrows in high, dry spots in the ground, but they like to hunt their food in shady, cool, moist soil. This is why moles often dig up well-watered parks and lawns.
Moles often den under large trees, buildings and sidewalks.
Moles are root destroyers. In their efforts at digging and finding food, moles will hurt vegetation by uprooting it. Lawn-mower blades can be mangled and destroyed when they move over mole tunnels and molehills.
In practice, packing the soil with a roller or reducing soil moisture may make an area less habitable for moles. Because moles feed largely on insects and worms, the use of certain insecticides to control these organisms may reduce their food supply, causing them to leave the area. However, before leaving, the moles may increase their digging in search of food, thereby possibly increasing damage to turf or garden areas.
