The most abundant Vole in New York State is the gray colored Meadow Vole. Length of 5.5" to 7.5" compact stocky body with short legs and short tails, small eyes with ears not very visible.
Look for shallow runways below the surface 1 to 2 inches wide, each burrow system may contain several adults and young. They prefer grassy areas, under mulch, along walkways so many families will notice tunneling in their yards. Sometimes it's not totally visible but the tunnels will give way under foot and you wonder what is happening to your lovely turf. Damaged tree saplings will have non uniformed gnaw marks, irregular patches and irregular angles about 1/8" wide and 3/8" long and 1/16" deep. Rabbits differ because they neatly clip branches at a 45 degree angle.
Voles do Not hibernate and rapid increase of populations can occur if not controlled.
They are in your yard and garden because they eat a variety of plant grasses and forbs. They store seeds, tubers and bulbs in late summer and will eat bark in fall and winter. They occasionally will eat insects but primarily are herbivores.
Remove bird feeders or reduce spillage, remove or limit ground cover like lawn and cultivated areas (not actually practical if you enjoy having a lovely yard or garden), remove mulch 3 feet from trees and till the soil as often as you can.
Rather let Critterex sign you up for a year's maintenance contract (Voles do Not hibernate) or a once off "Blitz" to reduce population to a manageable level. We use CO natural gas fumes blown into their burrows to gently and humanely allow the voles to "rest in peace", best way to go and no need for a burial.
