Question: What can I do to eliminate gophers or moles in my lawn?

Answer: First, identify the pest accurately. Gophers are rodents and resemble squirrels in their head and facial features. They feed on roots they encounter while digging. They may also feed on above-ground plant parts that are near their tunnels. Gopher mounds are usually kidney-shaped and are made of finely sifted soils. Gopher mounds are usually larger, and they often line up with one another. Place poison baits in the tunnels, then seal up the holes you have made.

Note that ultrasonic devices and plants that are purported to drive gophers away are virtually useless.

Moles, by comparison, are related to bats. They are insectivores. They have no external ears, and their eyes are located within their ear canals. You will usually find them in cool, moist soils where there are ample supplies of grub worms and earthworms. Moles produce volcano-shaped mounds of soil clods. Control them with traps that are pushed into depressed areas of the surface tunnels. The traps are activated as the moles try to open the tunnels back up again.
