Look at what the damage does. If the lawn has raised, rope-like ridges and the occasional pile of loose dirt, you are looking at a mole. If the grass is clipped along narrow lanes, there are small open holes at the surface, and plants, bulbs or the bark at the base of young trees are being chewed, you are looking at voles. The two animals get mixed up all the time, and in Overland Park yards it is common to have the wrong one blamed for months before anyone checks.
The difference matters because they eat different things, so they need different handling. A mole is a hunter of earthworms and grubs and never eats your plants. A vole is a small rodent that lives on the plants themselves. Putting out the wrong kind of treatment for the wrong animal is the single most common reason a lawn plan does not work.
The rest of this page is a field guide you can use in your own yard in about fifteen minutes, followed by what to do once you know which animal you have.
The eastern mole is not a rodent. The Missouri Department of Conservation describes it as chipmunk-sized, with slate gray fur, a nearly hairless tail, huge palm-like front feet, and eyes that can barely do more than tell light from dark. It weighs between one and five ounces and spends its life underground in its own tunnel system. Its food is grubs, earthworms and other soil creatures.
Voles are a different family altogether. Kansas State University extension describes them as compact rodents, sometimes called meadow mice, with stocky bodies, big heads, short legs, small eyes, partly hidden ears and a tail only about an inch long. Adults weigh one to two ounces. Three species live in Kansas, the woodland, meadow and prairie vole, and the extension publication points out that you usually do not need to tell them apart to deal with the damage.
So one is an insect and worm eater that tunnels, and the other is a plant eater that runs through the grass. That one distinction predicts nearly everything about what you will see.
Take a walk with a flag or two and look for these signs in order.
Moles push soil up as they tunnel just under the turf, which makes the soft, raised ridge you can feel when you step on it. Voles do not dig that way. Meadow and prairie voles build surface runways, and the extension describes them as recognizable by closely clipped vegetation, travel lanes tucked under a layer of grass or dense ground cover. You may only notice them when you part the blades and see a worn, narrow path.
A mole leaves mounds of fresh soil where it pushes dirt up from a deeper tunnel. A vole leaves small open holes that lead down to runways and nesting areas. If you are seeing little holes but not piles of soil, your suspect list changes.
This is the most reliable clue. Kansas State staff list the vole menu as grass stems, roots, flower bulbs, and the stems of woody plants, which they sometimes girdle. In late summer and fall they store seeds, tubers and bulbs. In winter they may gnaw bark. A mole will never touch a tulip bulb on purpose, though its tunnel can lift a bulb out of position. If you have lost bulbs, root systems or the bottom of a young tree trunk, voles are the likelier explanation.
Voles leave tiny, closely spaced gnaw marks on woody plants. The extension publication gives the size as about an eighth of an inch wide and three-eighths of an inch long. That is small enough that people confuse it with rabbit damage. The same publication notes that rabbit girdling starts several inches above the soil, while vole damage sits at or below ground level.
Moles lift turf and make it spongy. Voles thin it. A patch where the grass has been cropped down to bare earth along a lane is a vole sign. A patch where the grass is intact but the ground feels hollow underfoot is a mole sign.
If you think you have a mole, test whether the ridge is in use. Step down on a short stretch of one until it is flat, mark it, and look again after a day or two. A mole that is still using that run will rebuild it. This is also how Titan’s technicians separate active runs from old ones before treating, and the mole control page describes the same repair check, with a window of a day or two.
Voles do not repair collapsed ridges because they are not tunneling a ridge in the first place. If you flatten a stretch and nothing happens, you have not ruled out voles. You have only ruled out that particular run as a mole route.
A word of caution. Some yards have both animals, and a vole can use an old mole tunnel as a convenient road. That is one reason a professional look is useful, because the damage on top does not always match what is underneath.
The city’s Wikipedia entry lists several creeks running through the city, including Turkey Creek, Indian Creek, Tomahawk Creek, Coffee Creek and Wolf Creek, plus tributaries of the Blue River. It also reports more than 1,800 acres of park land and open space, with the Overland Park Arboretum and Botanical Gardens covering 300 acres. That is a lot of green corridor running through a city of residential lots.
Corridors like these matter for lawns because ground cover next to a yard is exactly the shelter voles want, and soft, moist soil near creeks and drainage swales is where earthworms and grubs concentrate. The city also grew mostly through suburban development on open ground after it incorporated in 1960, which means plenty of lots with fresh sod laid over older farmland and a thick edge of ornamental beds.
The average yearly precipitation in the city is about 40 inches, according to the same source. Moist ground, mature landscaping and nearby green space together describe the conditions that suit both animals. It does not mean every lot has them. It means that a lawn that backs up to a greenbelt or a creek drainage should be watched more closely.
The first move is to take away the cover. Kansas State’s extension says that vegetation taller than six inches, snow cover, brush piles, leaves and low-hanging limbs all give voles protection, and that voles do not hibernate and stay active all year. Keeping turf mowed short, clearing leaf litter and dead branch piles, and pulling mulch back from the base of trees reduce what they can hide in. The publication also notes that sawdust and wood chip mulch provides good vole habitat, and it suggests keeping a vegetation-free ring about four feet across at the base of young trees.
The same publication points out that prevention beats cleanup after the damage is done, and that voles breed quickly for most of the year with litters nearly every month for the common species. That is why the animal can seem to appear overnight and why one clearing job rarely stays finished unless the cover stays gone.
Voles are a rodent, so we treat them with a rodent bait placed in active burrows, alongside changes that make the yard less inviting. We select and apply products according to label directions and explain preparation, re-entry and any household-specific precautions before service. If you have pets that roam the yard, tell the technician before anything is placed so the plan can account for them.
Mole damage is mostly cosmetic. The Missouri Department of Conservation says that in most cases moles do not need to be managed, and that they also aerate soil and eat insects that hurt lawns. If the damage is intolerable, the agency lists trapping as the most effective way to remove them and notes that no repellents are known to be effective. Our technicians skip kill traps because of the risk to pets and other non-target animals, and place bait only in tunnels confirmed as active.
One thing mole homeowners often do not realize is that grub killer alone seldom fixes it. Moles also eat earthworms, so removing grubs does not remove their food. That is a good reason to confirm the species before spending money on a lawn treatment, since the chemistry that helps with one problem does nothing for the other.
Timing can fool you. Kansas State’s extension says the voles in this region breed through most of the year, with peaks in spring and fall, and that their numbers swing from year to year, with a high point roughly every three to four years. A yard that had no trouble last year can have a lot of it this year without anything about your lawn changing.
Moles follow a more compact calendar. Missouri conservation staff report young born in March, April or May, which means fresh tunneling by young animals as the weather warms. Because voles stay active under snow cover and moles dig below the frost line in their permanent tunnels, a winter thaw can reveal damage that built up all winter without anyone seeing it.
That is why spring is the time most people finally notice. The turf is greening, the damage is exposed, and it is easy to assume everything started last week. A few photos taken in March, with a coin or a tape measure in frame, give you something to compare against in May.
Whether you call a company or handle it yourself, a short list of observations saves time and gets you a better answer. Write down where on the lot the damage is, how long you think it has been there, whether any plants are being chewed, and whether the ridges rebuild after you flatten them. Note whether the yard backs onto a creek, a park or an open field. Mention pets, play areas and any vegetable beds, because those change what is practical.
A good provider will want to walk the damage with you and will tell you which animal they think it is and why. If the answer is vague, or if someone proposes the same treatment before looking, it is worth asking again.
Treating a vole problem like a mole problem leaves the plants being eaten while you watch ridges that were never the issue. Treating a mole problem like a vole problem means putting rodent bait where there is no rodent at all. Both mistakes cost a season. A short inspection that identifies the animal before anything is placed is the step that keeps the rest of the job pointed the right way.
If you want that inspection, our mole control page explains how the visit works, and the Overland Park pest control page lists everything else we do in the city. Voles are rodents, so our rodent control in Overland Park page may also be relevant if you are seeing activity near the house. For general yard habits, see how to stop pests from moving into a yard, and for repeat trouble ask about Titan Yard Defense.
This is general information and not legal advice. Rules on controlling wildlife on your own property can differ, so confirm current guidance with the Kansas Department of Wildlife and Parks or the Missouri Department of Conservation before trapping or shooting any animal.
How can I tell moles from voles fast?
Moles make raised ridges and soil mounds and never eat plants. Voles make small open holes and clipped lanes and chew roots, bulbs and bark. Chewed plants point to voles.
Do moles eat my plant roots?
No. Moles feed on grubs, earthworms and other soil creatures. If roots or bulbs are missing, the likelier cause is voles, though a mole tunnel can loosen a plant so it looks damaged.
Can I have both at once?
Yes. Voles will sometimes use old mole tunnels, and a yard backing onto green space can host both. That is why checking what is being eaten, and not only what the ridges look like, helps.
Will mowing short help with voles?
It helps remove the cover voles use. K-State’s extension says vegetation above six inches is good habitat for them, so keeping grass lower and clearing leaves and brush piles is a sensible first step.
Do voles come into the house?
Kansas State’s extension says voles do not commonly invade homes. If you hear scratching inside a wall or attic, that is more likely mice or another rodent, and rodent control is a better place to start.
Should I pick up a mole or vole?
Wild animals should not be handled. If anyone is bitten or scratched, that is a question for your doctor, and a pet that caught one should see a veterinarian.
