Problem: Moles (Lawn)
Moles are small rodents that live underground. They feed on grubs, earthworms, and other insects. Moles are 4 to 6 inches long, with velvety fur and small hidden eyes. They use their strong forelegs, with long trowellike claws, to dig and push the soil as they move through the ground. As they mine their way through the soil, they sever the grass roots and raise the sod. These raised and loosened areas dry out quickly. Moles are also objectionable because their ridges give the lawn an uneven surface that can result in scalping when mowed.
Moles are often attracted to a lawn by grubs. If grubs are present, treat the lawn for grubs. If moles are a problem when there are no grubs, they are probably feeding on earthworms. Traps set on active tunnels are the most effective way to control them. Several kinds of mole traps are available in hardware and rental stores. Poison baits are not always effective with moles and should be used with caution around children and pets.
