Quick Answer
Gophers, moles, and voles all create tunnels and mounds in lawns, but they are different animals. Gophers create large, fan-shaped or crescent-shaped mounds with a plugged hole, and eat plant roots. Moles create volcano-shaped mounds of fine soil, and eat insects and grubs (not plants). Voles do not create mounds — they create surface runways in grass and eat plant stems and roots. Identifying which animal is causing the damage is the first step to effective control.
Gopher vs Mole vs Vole: Mounds, Tunnels & Damage Guide
If you have tunnels and mounds in your lawn, you need to identify the culprit before you can treat the problem effectively. Each of these animals requires a different approach. Gophers need trapping, moles need grub control or trapping, and voles need habitat modification and exclusion.

Mound Identification: The Key Differentiator
Gopher Mounds
Gopher mounds are fan-shaped or crescent-shaped, 10-20 inches in diameter, with coarse, clumpy soil. The hole is plugged with soil and is off-center. Gophers push soil out of their burrow in one direction, creating the fan shape. You will typically see a series of mounds in a line, connected by underground tunnels.
Mole Mounds
Mole mounds are volcano-shaped or cone-shaped, 6-12 inches in diameter, with fine, fluffy soil that looks like it has been pulverized. The hole is plugged with soil in the center of the mound. Moles also create surface tunnels that look like raised ridges of soil running across your lawn.
Vole Signs
Voles do not create mounds. Instead, they create surface runways — narrow (1-2 inch wide) trails through the grass, often along the edge of the lawn or under the cover of mulch. They also create small tunnels at the soil surface. Vole damage includes girdled trees (gnawed bark at the base) and eaten grass.
Damage Comparison
| Damage Type | Gopher | Mole | Vole |
|---|---|---|---|
| Lawn mounds | Yes (fan-shaped) | Yes (volcano-shaped) | No |
| Surface tunnels | No | Yes (raised ridges) | Yes (runways in grass) |
| Eaten plants | Pulled underground (roots only) | No (eats insects only) | Eaten stems, leaves, bark |
| Girdled trees | Rare | No | Common (winter) |
| Dead grass patches | Above tunnels | Above surface tunnels | Runway paths |
| Structural damage | Can undermine foundations | Rare | No |
Control Methods
Gopher Control
Gophers are best controlled with trapping. Pocket gopher traps placed in active tunnels are effective. Baiting with poison baits is also used but carries risks to pets and wildlife. Flooding and fumigation are less effective.
Mole Control
Mole control involves reducing their food source (grubs) and trapping. Grub control with beneficial nematodes or milky spore can make your lawn less attractive to moles. Trapping with harpoon or scissor-jaw traps is the most effective removal method.
Vole Control
Vole control focuses on habitat modification: mow grass short, remove mulch and ground cover, and protect tree trunks with hardware cloth. Trapping is effective for small populations. Repellents and exclusion fencing are also options.

FAQ: Gopher vs Mole vs Vole
Do moles eat plant roots?
No. Moles are insectivores and eat earthworms, grubs, and insects. They do not eat plant roots. The damage to lawns from moles is caused by their tunneling, which dries out grass roots.
Can I have both gophers and moles?
Yes, it is possible to have both in the same yard. The mounds look different — gopher mounds are fan-shaped with coarse soil, while mole mounds are volcano-shaped with fine soil.
