Voles (meadow mice) are small, stocky rodents with short tails, small ears, and blunt snouts. They're often confused with mice but have smaller eyes, shorter tails (about 1/3 body length), and stockier bodies. In Idaho, the montane vole and meadow vole are most common.
Behavior
Voles Behavior & Habits
Understanding how voles behave helps prevent infestations
Voles dig shallow tunnel systems just below the soil surface or under snow cover. They're active day and night, year-round. One pair can produce 100+ offspring per year. They eat grass, roots, bulbs, and bark, and they do serious damage to fruit trees and ornamentals in winter.
Dangers
Voles Risks & Dangers
What voles can do to your health and property
Health Risks
Voles rarely come inside, so direct health risks are low. They can carry ticks and fleas that pass on disease, so don't handle them without gloves.
Property Damage
Voles cause significant landscape damage. They girdle trees and shrubs (eating bark around the base), destroy bulbs and root vegetables, kill lawns with their runway systems, and can damage irrigation lines.
Warning Signs
Signs of Voles Infestation
Look for these indicators in your home
Surface runways (1-2 inch wide paths) through grass
Small round holes (1.5 inches) at ground level
Gnaw marks on tree bark near ground level
Dead patches in lawn following runway patterns
Missing or damaged bulbs and root vegetables
Droppings (small, greenish) in runways
Voles in Boise & the Treasure Valley
Voles are everywhere across the Treasure Valley, especially in older Boise neighborhoods like the North End and Eagle subdivisions where mature landscaping gives them cover. We see the worst tree damage in late February and early March, when the last snow melts back and homeowners find girdled trunks on their fruit trees. Meridian and Eagle properties that back up to greenbelts, canals, or open fields get hit hardest year after year.
Our Solution
How We Eliminate Voles
Professional treatment for complete elimination
Vole control takes a few angles at once. We set bait in active runway systems, walk your yard with you to spot the habitat changes that make the biggest difference, and add hardware-cloth guards around fruit trees and young shrubs. Heavier infestations get targeted trapping and a follow-up to make sure the population is down. Just $49 to get started on a subscription plan.

Voles Questions Answered
Common questions about identification, prevention, and treatment
What's the difference between voles and moles?
Voles are small rodents that eat plants and create surface runways. Moles are insectivores with large digging claws that create raised tunnel ridges. Voles damage plants; moles damage lawns but actually eat grubs and insects.
Why are voles killing my trees?
Voles gnaw bark off trees at the base (girdling), especially under snow cover in winter. Once bark is removed around the entire trunk, the tree dies. Protect young trees with hardware cloth guards extending 18 inches high.
Do cats control voles?
Cats, owls, and hawks all help knock down vole numbers, but they rarely wipe out a population. Voles breed too fast (5-10 litters a year) for predators to keep up on their own. If voles are tearing up your yard, give us a call at (208) 297-7947.
