Gopher vs. Mole: How to Tell What's Destroying Your Yard

Gophers and moles both damage Southern California lawns — but they are different animals requiring different treatments. Correctly identifying which pest you have is the first step to effective control.

Gopher Damage: What to Look For

Pocket gophers create fan-shaped or crescent-shaped mounds of loose dirt. The plug (entrance hole) is visible on one side of the mound. Gophers push excavated dirt out of one end of their tunnel, creating asymmetrical mounds 4-12 inches high. They eat plant roots, bulbs, and tubers — you will often see plants wilting with intact stems because the root system has been eaten from below. Gophers also frequently cut drip irrigation lines.

Mole Damage: What to Look For

Moles create raised ridges or runways just below the soil surface, and volcano-shaped mounds with a central plug hole — unlike the asymmetrical gopher mound. Mole runways feel spongy underfoot and often follow fence lines or lawn edges. Moles eat earthworms and grubs, not plants. If your plants are dying, it is almost certainly a gopher.

Which Is More Common in Southern California?

Gophers are far more common throughout most of Southern California. Moles are more common in coastal areas with high soil moisture and heavy earthworm populations — parts of coastal LA and Orange County. If you are in an inland valley, gophers are almost certainly the culprit.

Treatment Differences

Gopher control requires trapping in the main tunnel system. Mole control also uses trapping but targets the shallow surface runways. The same exterminator typically handles both, but trap placement differs significantly. If unsure which pest you have, call for an inspection — an experienced exterminator identifies the pest from mound shape and tunnel structure within minutes.
