The meadow vole can nest in a variety of habitats.
Freezing nights and shortening daylight in the fall tranquilizes the landscape — not counting the insatiable meadow vole that remains active throughout the year. The vole, also called a meadow mouse, is a ground dwelling rodent with a chunky grayish brown appearance, tiny ears and short tail.
Commencing in late fall and continuing through winter into early spring, voles cause a variety of damage to landscapes. Runways and seemingly endless tunnels in lawns, shaved tree bark and roots, and the mysterious disappearance of flowering bulbs and tubers in spring are classic blueprints of vole damage. Under snow cover, voles can venture safely to any part of the landscape, and quite often homeowners do not notice the damage until the spring melt.
Mowing and cleaning up the yard can limit destruction and being vigilant and taking proactive steps in the fall is the key to controlling voles.
Ponds, stream banks, orchards, old fields, fence rows, pastures, hay fields, grassy weeds and ground covers are ideal habitats for voles. Backyard logs, undisturbed compost piles, tall ornamental grasses, bushy evergreen shrubs and debris in the urban landscape can also provide a nesting place for voles.
Trapping or any other control strategies when the snow is on the ground has proven ineffective. Here are a series of tips for managing this pest.
The landscape should be scouted in fall for voles. Sightings of fresh grass clippings, tunnels, droppings around large grasses, nests, and chewed fruits are telltale signs of their abundance in the landscape.
