Every spring in Iowa, when the snow finally melts, some homeowners find a lawn that looks like a highway system was installed over winter. Those 2-inch-wide paths winding through the grass, the gnawed bark at the base of young trees and shrubs, the hollowed-out bulbs in the garden — that’s vole damage. Unlike moles, voles actually eat plants. And unlike most pests, their populations can explode from a few to dozens in a single season. By the time you see the full extent of the damage in spring, they’ve had months to work under the snow.

Signs of Vole Infestation

  • Surface runways — 2-inch-wide paths worn through grass at ground level. These narrow trails run between burrow entrances and feeding areas. Very visible after snow melt.
  • Gnawed bark — Voles girdle trees and shrubs by chewing through the bark at the base, often just above or below the soil line. A tree that’s girdled all the way around will die. This is one of the most damaging things voles do.
  • Damaged bulbs and roots — Voles eat plant roots, flower bulbs, and underground plant material. Finding missing or destroyed bulbs in spring, or wilting plants with no apparent above-ground cause, often points to vole root feeding.
  • Burrow entrances — Small, golf-ball-sized holes at ground level in dense grass or mulch beds. Multiple entrances connected by surface runways.
  • Grass patches dying in irregular shapes — Vole feeding on grass roots and crowns can kill turf in irregular patches, especially under snow cover.

Why Voles Are a Significant Problem in Adel

Iowa winters are prime vole habitat. Snow cover acts as insulation, keeping ground temperatures moderate and hiding voles from aerial predators. The deeper the snow and the longer it stays, the more time voles have to breed and feed without exposure. Adel’s Dallas County winters consistently provide this cover.

Vole populations can double and redouble rapidly. A single breeding pair can produce multiple litters in a season, with young reaching reproductive maturity in just a few weeks. What starts as a small vole population in fall can become dozens by spring.

Adel’s mix of older homes and new construction creates ideal conditions for pest pressure year-round. Properties in the county seat of Dallas County, just west of Des Moines with dense ground cover, heavy mulch beds, ornamental grasses, and established shrub plantings provide ideal vole habitat — dense, low-to-the-ground cover where they can move and feed without predator exposure.

Our Vole Control Process

Vole control works best when it’s addressed before populations build — ideally in fall before snow arrives, or as early in spring as conditions allow.

Baiting: Rodenticide bait placed in active runways and near burrow entrances is an effective population reduction tool. We use bait stations designed to target voles while reducing exposure risk to non-target animals.

Trapping: Snap traps placed perpendicular to active runways in high-activity areas provide additional control, especially where baiting is impractical.

Exclusion for trees and shrubs: Hardware cloth cylinders around tree trunks and the base of valuable shrubs prevent bark girdling. This is especially important for young trees where girdling can be fatal. We can advise on installation if this is warranted for your property.

Habitat modification: Reducing dense ground cover near the foundation, pulling mulch back from tree bases, and keeping grass mowed short reduces the protected habitat voles depend on. Less cover means more predator exposure and less vole survivorship.
