Are There Voles in Illinois?
Yes, voles are common throughout Illinois in grasslands, prairies, and fields. Meadow voles live from central Illinois to northeastern marshes, creating characteristic runways through grass. Most residents don't see voles because they are secretive and most active at twilight. These small rodents play an important role in grassland ecosystems by serving as prey for raptors and other predators.

Where Voles Are Found in Illinois
Meadow voles occur across Illinois in suitable habitats. The state's northern regions, including areas around the Skokie Marshes and Illinois Beach State Park in Cook County, support healthy vole populations in wet grasslands. Central Illinois, with its agricultural heartland stretching from Champaign to Macon County, provides extensive meadow and pasture habitat for voles. The Illinois River floodplain wetlands and adjacent grasslands host numerous voles from LaSalle County to Fulton County. Eastern Illinois around the Embarras River and in Clark and Edgar Counties offers productive habitat. The sand prairie remnants in northeastern Illinois and the drained wetland areas that have reverted to grassland all support vole populations. Voles generally avoid heavily wooded areas and forests but thrive wherever grasses and forbs dominate. You can find voles in hayfields, pastures, native prairie restoration areas, and natural wetland margins throughout the state. While they occur in every Illinois county with suitable habitat, their numbers vary by year and season. For more on vole in Illinois, see ourIllinois vole guide.
When Voles Are Most Active in Illinois
Voles are active year-round in Illinois and do not hibernate. Their activity patterns follow a predictable cycle tied to food availability and reproduction. Fall and winter are peak population periods when vole numbers surge across Illinois grasslands. This is when runway systems become most obvious and predator activity increases. Spring brings a second surge in vole activity as females produce multiple litters in April and May. Summer sees some population decline as heat and drier conditions reduce grass quality. Voles are primarily nocturnal and most active during twilight hours and throughout the night. Early morning hours and late afternoon often reveal fresh runway activity in grass. During wet springs, vole populations in Illinois may temporarily decline as flooding affects burrow systems. Conversely, mild winters allow populations to remain high through winter, providing abundant food for predators. Understanding these seasonal patterns helps predict where and when you might encounter vole evidence like runways and burrows. The best time to observe voles or their signs is fall through early spring. You can also browseIllinois wildlife.
How to Identify a Vole
Voles are small rodents resembling mice but with stockier builds and shorter tails. Adult meadow voles in Illinois typically measure 4 to 5 inches long, including a short tail of roughly one inch. Their fur is dense and typically brown, gray, or reddish-brown with darker undertones. The eyes are small and dark. Unlike mice, voles have tiny ears mostly hidden in fur. Their molars are flat and rootless, adapted for grinding plant material. Males and females look similar, though females may appear slightly larger when pregnant. Voles leave distinctive surface runways about one inch wide through grass where they travel regularly. These runways are cleared of vegetation and compacted by repeated use. Droppings are small, oval, and dark, typically found along runways or in burrow entrances. Fresh droppings indicate recent activity. Vole burrows have small openings about one quarter inch in diameter. A hand lens reveals the vole's teeth are bright orange on the outer surfaces. This orange coloration is a key field mark distinguishing voles from similarly sized mice and shrews. See all of ourwildlife guides.
Where Vole Populations Concentrate in Illinois
Voles reach highest densities in Illinois where native grasses remain intact or in secondary grasslands recovering from agriculture. The dry sand prairies of northeastern Illinois, including sites protected by the Illinois Nature Conservancy, host strong vole populations. Wetland margins along the Illinois River support abundant voles, particularly in Cook County, Will County, and Grundy County locations. State natural areas designated for grassland restoration in central Illinois like Springlake Park and Horseshoe Lake support increasing vole populations as grass structure improves. The Kankakee Sands area in Kankakee County has restored prairie with healthy vole populations. Marshy areas around Des Plaines River in the Chicago region provide excellent vole habitat. Talus slopes and rocky areas generally do not support voles. Areas managed specifically for native plant restoration, such as some county forest preserves, develop excellent vole habitat over time. Agricultural hayfields with minimal disturbance and dense grass cover often harbor more voles than frequently tilled cropland. Old field transitions where weeds and native grasses have returned can have surprising vole densities. Visiting local wildlife areas or natural areas in your region provides the best chance to observe vole runways and evidence of their presence.

Typical Vole Behavior and Diet
Voles are herbivores that graze on grasses and eat roots, seeds, and forbs throughout the year. They consume their own weight in vegetation daily, grinding plant material with their flat molars. In winter, voles rely on dry grasses above ground and stored seeds found in their underground chambers. They also gnaw bark from young saplings in winter, sometimes causing damage to seedlings and small trees. Voles create extensive burrow systems and surface runways as they search for food. They are solitary and territorial, with each vole defending its own feeding and nesting area. Females produce multiple litters of 4 to 5 pups each year, with some years seeing three or more litters depending on food availability. Young voles mature quickly and breed within weeks of birth. Voles are crepuscular and nocturnal, meaning they are most active at dawn, dusk, and throughout the night. During daylight hours they remain in burrows or under dense grass cover. They make various ultrasonic calls to communicate with other voles. Despite their secretive nature, their runway systems and burrows reveal their presence. Voles commonly live 3 to 4 months in the wild, though some individuals may live longer. Read more aboutvole in Illinois.
Living with Voles in Illinois
Voles are a natural part of Illinois ecosystems and generally do not pose safety risks to people. Their presence is actually a sign of healthy grassland habitat. Voles serve as a primary food source for hawks, owls, foxes, and snakes, making them crucial to the food web. If vole runways appear in your yard or garden in Illinois, exclusion methods like fencing and vegetation management are effective. Remove tall dense grass near structures to make the area less attractive to voles. Wire fencing buried at least 12 inches below ground can protect young plants. Trapping is rarely necessary and removal from suitable habitat often fails as other voles eventually recolonize the area. Voles are protected from harvest in Illinois and have no hunting season. They are prey animals and their population fluctuations are natural, varying from year to year. Some years Illinois sees population peaks followed by population crashes. Large scale rodent control is generally not recommended and damages the ecosystem balance. Accepting voles as part of the landscape acknowledges their ecological value. Educating children about voles and their role increases appreciation for these often overlooked rodents. Watching for vole runways is an engaging outdoor activity that connects people to grassland ecology. Browsewildlife in Illinoisfor related pages.
Species Confused with Voles
Several other small rodents in Illinois can be mistaken for voles. The house mouse is commonly confused with voles but has a longer tail roughly equal to its head and body length, while voles have short stubby tails. Mice also have large ears visible on the sides of their head, whereas vole ears are tiny and hidden in fur. The white footed mouse is reddish-brown but again has a long tail and large ears. Shrews resemble voles in size and build but have pointed snouts and teeth adapted for eating insects rather than plants. Shrews are also much more aggressive and likely to bite than voles. The star nosed mole, found in northern Illinois, is sometimes confused with voles but has a distinctive star shaped nose and larger front claws for digging. Meadow jumping mice look similar to voles but have longer hind legs adapted for jumping and a longer tail. In winter, distinguishing frozen dead specimens requires careful examination. The vole's orange tinted teeth, small ears, and short tail are the reliable field marks that separate them. If you find a small rodent during /wildlife exploration, these features help with accurate identification.
Frequently Asked Questions About Illinois Voles
What do voles eat and how much do they consume? Voles are strict herbivores eating grasses, clover, seeds, roots, and forbs. An adult vole eats roughly its own body weight daily, consuming vegetation year-round. Can voles damage my garden or landscape? Voles can damage young plants and seedlings by chewing roots or gnawing bark from saplings. Excluding them through burial fencing or removing tall grass that provides cover reduces damage. How long do voles live? Voles typically live 3 to 4 months in nature due to predation. Some individuals in protected settings may live up to 2 years. Why do I see so many vole runways some years but not others? Vole populations follow boom and bust cycles influenced by food availability, weather, and predation rates. Years with abundant seed production and mild winters often see population explosions. Where should I go to see voles or their signs in Illinois? Visit natural areas managed for grassland restoration, state parks with prairie sections, or wildlife refuges. Look for characteristic narrow runway systems through dense grass, particularly in fall and winter.
