Since moles feed heavily on grubworms, the elimination of the grubs will generally decrease mole activity in a lawn. Grubworms can be controlled either with chemicals or with milky spore disease, a relatively harmless biological control agent. Read the label for more specific instructions, precautions and suggestions. After treatment with any of these insecticides, soak the lawn surface thoroughly. Keep pets and children off of the treated area until it has dried.
Moles often move into lawns from adjacent wooded areas, ravines or similar areas.
Treatment of a 20-40 foot barrier strip, along the side of the lawn adjacent to the refuge, will usually discourage moles and make it unnecessary to treat the entire lawn.
