Voles and gophers both damage yards and gardens, but they’re very different animals that leave distinct signs, eat different parts of plants, and require different control strategies. Knowing which one you’re dealing with is the first step to protecting your landscape.
How They Look
Voles are small, mouse-like rodents with short tails, rounded ears, and compact bodies. They typically weigh just an ounce or two and measure around 5 to 7 inches long including the tail. People often mistake them for field mice, and the resemblance is close enough that “meadow mouse” is a common nickname.
Pocket gophers are considerably larger, stocky rodents with powerful front claws built for digging. They get the “pocket” name from fur-lined cheek pouches they use to carry food. Adults range from about 6 to 10 inches long (body only) depending on species, with small eyes, tiny ears that sit flat against the head, and prominent front teeth that are always visible, even when their mouth is closed. Where a vole looks like a chunky mouse, a gopher looks purpose-built for tunneling.
The Damage They Leave Behind
This is usually how homeowners figure out which pest they have, because the two animals leave completely different calling cards.
Gophers create distinctive crescent or horseshoe-shaped mounds of soil with a plug off to one side. These mounds appear where lateral tunnels reach the surface, and a single tunnel system can stretch as far as 200 yards underground. The tunnels themselves run 4 to 18 inches below the surface, averaging about 3 inches in diameter. You rarely see a gopher above ground. Their entire operation happens beneath your lawn.
Voles work at the surface. Look for narrow, well-worn runways through grass that connect small burrow openings. These trails are typically 1 to 2 inches wide and become especially visible after snow melts in spring. Grass usually covers the burrow entrances. Unlike gophers, voles don’t push up soil mounds, so their presence is subtler until you notice the network of trampled paths crisscrossing your yard.
What They Eat and How They Damage Plants
Both animals are herbivores, but they attack plants from opposite directions.
Gophers feed mostly on roots. They pull plants down into their tunnels from below, and they chew through root systems of trees and shrubs over time. A gopher working on a tree’s roots can cause a slow decline in vigor that eventually kills the tree. Because the damage is underground, you may not realize what’s happening until the tree starts looking stressed or leaning. Gophers also store food in cache chambers as deep as 5 to 6 feet below the surface.
Voles feed on stems, bark, seeds, and grass at or just above ground level. Their most destructive habit is girdling: chewing bark in a ring around the base of young trees and shrubs. This feeding is most intense in fall and winter, often hidden under snow cover. The gnaw marks are small (roughly 1/8 inch wide by 3/8 inch long) but devastating in aggregate. A young tree girdled more than 50% around its trunk has a low survival rate. You may not discover the damage until spring, by which point the tree is already in trouble.
A useful shorthand: gophers girdle trees below ground by eating roots, while voles girdle trees above ground by stripping bark.
Where and How They Live
Pocket gophers are solitary and territorial. Each gopher maintains its own tunnel system, which includes a main tunnel with several branching laterals, plus deeper chambers for nesting and food storage. Those deeper chambers can sit 5 to 6 feet below the surface, helping gophers stay warm in winter. They’re active year-round, day and night, and rarely come above ground.
Voles are social animals that live in colonies. Their burrow systems are shallow, often just below the turf surface, and they spend considerable time above ground traveling their runway network. Vole populations can fluctuate dramatically from year to year, sometimes booming to very high densities when conditions are right. They’re also active year-round but are most visible (or at least their damage is) after winter snow cover melts.
Reproduction and Population Growth
Voles reproduce at a startling rate. Some species can produce five or more litters per year, with several young per litter. Population explosions are common, and a yard with a few voles in spring can be overrun by fall.
Gophers breed more slowly. Females produce one to two litters per year on average (up to three on irrigated land), with about five young per litter. Breeding peaks in late winter or early spring. Even so, on properties with plentiful food, populations can build to 30 to 40 gophers per acre if left unchecked. Because each gopher maintains its own extensive tunnel system, even modest populations can chew through a lot of landscape.
Control Strategies
Effective control looks different for each animal because of how differently they live.
Gopher Control
Trapping is the most reliable method for homeowners. Pincher-style traps (sometimes called pincer traps) are the most common choice. They sit inside the tunnel, and the gopher triggers them by pushing against a vertical pan. Studies have found that certain pincher designs, particularly the Gophinator and Cinch traps, outperform other models. To set them, you dig down to an active tunnel, place traps in both directions, and cover the opening to block light.
Toxic baits are also used, particularly in agricultural settings. Chemical and mechanical repellents, on the other hand, have not been shown to work against gophers in any scientific testing. Vibrating stakes, castor oil granules, and similar products marketed as gopher repellents lack evidence of effectiveness.
Vole Control
Because voles live at the surface, the approach is different. Standard snap-style mouse traps placed along active runways, baited with peanut butter or apple, are effective for small populations. Keeping grass mowed short and clearing mulch, leaf litter, and ground cover away from the base of trees removes the habitat voles depend on for protection from predators. For young trees, wrapping the lower trunk with hardware cloth or a plastic guard prevents bark girdling. The guard should extend a few inches below the soil line and high enough to sit above expected snow depth.
Encouraging predators also helps. Owls, hawks, foxes, and even house cats all hunt voles effectively. Installing owl nest boxes is a long-term strategy that some orchardists and homeowners use to keep vole numbers manageable.
Quick Comparison
- Size: Voles are mouse-sized (1 to 2 ounces). Gophers are much larger (several ounces to over a pound depending on species).
- Yard signs: Voles leave surface runways in grass. Gophers leave horseshoe-shaped dirt mounds.
- Tunnel depth: Voles stay at or just below the surface. Gopher tunnels run 4 to 18 inches deep, with chambers as deep as 5 to 6 feet.
- Plant damage: Voles chew bark and stems above ground. Gophers eat roots below ground.
- Social behavior: Voles live in colonies. Gophers are solitary.
- Reproduction: Voles breed rapidly with multiple litters per year. Gophers produce one to two litters annually, averaging five young each.
- Best control: Voles respond to habitat modification and surface traps. Gophers require underground pincher traps or baiting.
