Homeowners are urged to correctly identify whether moles or voles are damaging their lawns, as the approach to control each pest differs, according to a May 14 press release. The distinction is important because moles and voles cause different types of damage and require specific removal strategies.
The press release highlights that moles tunnel underground in search of insects, creating raised tunnels and molehills that disrupt roots. In contrast, voles feed on plants, roots, bark, and grass, leaving surface runways and chewing visible bark. Identifying which animal is present is the first step before choosing traps, bait, or barriers.
The document explains that while both animals burrow and can harm gardens or lawns, they differ in classification and behavior. Moles have clawed forefeet for digging and long snouts to locate food underground. They are insectivores who live solitary lives almost exclusively below ground. Voles resemble mice but are larger with plump bodies; they are herbivores who eat a variety of plants above ground.
Damage from moles includes extensive tunneling beneath lawns—sometimes up to 18 feet per hour—and disruption of plant roots as well as possible harm to sprinkler heads or water lines. Vole damage primarily results from feeding on vegetation down to the crown at ground level; their runways also accumulate excrement that becomes visible after snow melts in spring. According to Dr. Martin Collinson from the University of Aberdeen: “In the case of the Iberian mole, we found that even though their eyes are permanently shut, they can see and run away from bright light…”
Control measures differ between pests: exclusion barriers may work for small areas against both animals but need finer mesh for voles than chicken wire; trapping is effective mainly for individual moles but less so for large vole populations; habitat modification such as mowing deters voles but does not impact moles significantly; baits can be used cautiously due to risks posed to pets.
The press release concludes by stressing the importance of understanding these differences: “Moles and voles differ in appearance, behavior, and damage to lawns. Effective control requires tailored methods considering diet, reproduction rates, and removal options.”
