Warranty Moles Moles live in the soil and feed on insects, earthworms, and other soil dwelling food sources. Their active tunneling under the soil surface can cause lawn damage as moles forage for food. The tunnels create ridges of soil throughout the lawn. The uplifted grass growing in these ridges often dies. Lawn mowers may scalp grass growing on the raised tunnels.
Moles can tunnel at the rate of one foot per minute.
These foraging tunnels may radiate randomly throughout the lawn. Moles are nocturnal. It is rare to see any tunneling activity during the day. New tunnels are made at night while moles are feeding. The only effective control for moles is trapping.
