Pocket Gophers
Family Geomyidae
Stout burrowing rodents that live almost entirely underground and feed on roots, tubers, and whole plants pulled down into their tunnels from below. Pocket gophers, common in the western and central states, can destroy vegetables and young trees fast, and their crescent-shaped soil mounds are the sign of an active animal in the bed.
🔎 How to spot it
Gophers are rarely seen, but their mounds give them away: fan- or crescent-shaped piles of loose soil with the hole plugged off to one side, unlike the volcano-shaped, centered mounds of moles. Look for plants that wilt or vanish, pulled down into the soil, roots gnawed and exposed, and clipped stems near tunnel openings. Fresh, soft mounds mean a gopher is active.
🥀 Damage it causes
Pocket gophers feed on roots, tubers, bulbs, and whole plants, often pulling a plant down into the burrow from below, and a single gopher can work down a garden row quickly. Plants with large taproots and fleshy roots are most vulnerable, and gophers also girdle and clip young trees and shrubs, gnaw irrigation lines, and undermine beds with their tunnels.
🛡️ Prevent it
Protect beds and individual plants with buried wire-mesh barriers, a quarter- to half-inch mesh fence buried about 18 inches deep, or line planting holes and raised beds with hardware cloth and wire baskets around the roots of valued plants. Keep an eye out for fresh mounds so you can act before a gopher works through a row. Reduce dense weedy cover that supports them.
🧯 If it is already here
Trapping is the most effective and immediate control: place gopher traps in the main runway, found by probing near a fresh mound, and check and reset them. Burrow baits are also used where legal and appropriate. Because a new gopher can move into vacated tunnels, stay watchful for fresh mounds and protect prized plants with wire baskets.
💡 Good to know
The crescent-shaped, plugged mound is the easy way to tell a pocket gopher from a mole, whose mounds are round and centered, and the difference matters because gophers truly eat plants while moles do not. Gophers move into open tunnels readily, so ongoing watchfulness for fresh mounds, plus wire baskets around favorite plants, is the lasting defense.
