Answer: Moles feed on grubs and earthworms living in your lawn or garden. The damage they do is to plant roots while they are tunneling. Your first consideration should be to control the grub population in your lawn (have you considered beneficial nematodes or milky spore?) and determine how serious a problem the moles are. Some gardeners consider moles beneficial because they are such good insectivores. If you have a major problem with them, your first task in treating moles is to determine which of their runways are active. You can do this be tramping down areas of raised soil that indicate tunneling. The tunnels that are raised a day later are active. Some methods of treatment are flushing with water (best done in the spring), or protecting your garden by burying a fencing of small mesh, tightly woven hardware cloth, or a low cement wall. You could also try trapping - live-in-a-pit-trap or using a lethal scissors type trap.
