Check the feet and face first, then look at the pattern of tracks or plant damage. A mole has broad, clawed digging forefeet and usually works underground; a shrew is tiny, with a pointed snout and small feet; a vole looks mouse-like, with visible eyes and prominent front incisors. Yard signs can help, but tunnels alone do not identify the animal.
Quick differences between moles, shrews, and voles
These small mammals can share tunnels and turn up in the same yard, but their bodies, feeding habits, and signs differ. Moles are specialized diggers that mainly eat insects and other soil invertebrates. Shrews are small predators with pointed snouts and small feet. Voles are rodents that eat vegetation and leave mouse-like gnawing evidence. Compare several clues rather than relying on a hole, tunnel, or pointed nose by itself.
| Clue | Mole | Shrew | Vole |
|---|---|---|---|
| Overall appearance | Compact, velvety body; tiny eyes and ear openings concealed in fur | Very small body, long pointed snout, tiny eyes | Mouse-like body, blunt face, noticeable eyes, small ears |
| Feet and teeth | Broad, powerful forefeet with long claws for digging | Small front feet; no broad digging paddles | Prominent front incisors for gnawing |
| Typical food | Insects and other soil invertebrates, including worms | Insects and other small prey | Grasses, seeds, roots, bulbs, and other plant material |
| Common yard sign | Raised subsurface ridges and loosened-soil mounds | May travel through another mammal’s tunnel or runway | Surface trails through grass, gnawing, or plant damage |
| Important caution | Tunneling can disrupt roots even though plant material is not its main food | A tunnel may belong to or be reused from another animal | Voles may use mole runways, so a tunnel does not prove a mole caused nearby plant damage |
This is a general comparison, not a species-level field key. The Penn State Extension guide, updated December 15, 2025, is Pennsylvania-based, and species and size can vary by location.

The fastest decision path
When you have only a few seconds to observe an animal, use this order: feet, face, eyes and ears, teeth, then surroundings. Broad forefeet that turn outward and carry long claws are a strong mole clue. Small feet on a very small, pointed-snouted animal are more consistent with a shrew. A blunt face, visible eyes, small ears, and conspicuous front incisors indicate a vole. If the animal disappears before you can see those details, do not force an identification from a single feature.

- Ask whether the animal is built to dig. Look for wide, paddle-like forefeet. These are the most distinctive external feature of a mole.
- Check the snout and head. A shrew has a notably long, pointed snout. A vole has a relatively blunt, mouse-like face. A mole’s small eyes and ear openings are concealed in its fur.
- Look for eyes, ears, and teeth. Noticeable eyes and small ears support a vole identification. Prominent front incisors are another vole clue.
- Match the animal to the sign. Subsurface ridges and loosened soil fit mole digging; surface trails and gnawing fit voles. A tunnel or runway by itself remains inconclusive.
How to identify one when you can see it
Start with the forefeet
Broad, outward-facing forefeet with long claws are the strongest visual clue for a mole. Those powerful paddles are built for moving soil. A shrew’s front feet are much smaller, while a vole has ordinary-looking feet rather than the mole’s digging equipment. If you can safely observe the animal, feet are often more useful than a quick impression of its face.
Try to see the whole front half of the body rather than relying on a fleeting glimpse. A mole’s compact body and concealed facial openings can make it look like a dark, featureless shape at first. The forefeet reveal its specialization. Conversely, a tiny animal with a pointed snout but no broad digging feet should not automatically be labeled a mole or a shrew until its body shape and eyes are compared.
Compare the face, eyes, and body shape
A mole’s eyes and ear openings are small and concealed in fur; that does not mean it is accurate to call moles blind. A shrew has a very pointed snout, tiny eyes, and a small body. A vole has a blunter face, noticeable eyes, and small ears, giving it a mouse-like appearance. Voles also have prominent front incisors, the teeth they use to gnaw plants.

A pointed nose by itself is not enough to identify a shrew. Check the animal’s overall size and feet as well: a tiny, pointed-snouted animal with small feet is consistent with a shrew, while a mole’s digging forefeet are distinctive. A visible-eyed, blunt-faced animal with obvious incisors points toward a vole. This whole-body comparison is safer than treating one silhouette feature as a definitive field mark.
Use size only as a supporting clue
Penn State Extension gives approximate body lengths of 3–4 inches for shrews and 4–6 inches for voles in its guide updated December 15, 2025. These are general descriptions in a Pennsylvania-focused source, not universal ranges for every species or region. Body length should support an identification, not replace the more distinctive clues of feet, face, and teeth.
Estimate body length without counting the tail unless a local guide specifies otherwise. A photograph beside a ruler, coin, or other familiar object is more useful than memory. Do not reject an otherwise convincing identification because an individual appears slightly outside a general range; local species and age can affect apparent size.
How to identify them from tunnels, ridges, and plant damage
Raised ridges and mounds suggest mole digging
Raised ridges in a lawn or mounds of loosened soil are consistent with underground digging by moles. A ridge is evidence of activity below the surface, not proof that the animal is eating plants. Moles primarily feed on insects and other invertebrates, including worms. Their tunnels can nevertheless disturb roots as they pass through soil.

Describe the sign precisely. A long, raised line under turf indicates soil has been displaced below the surface. A mound of loose soil indicates excavation or soil pushed upward. These observations establish digging activity, but they do not tell you whether a vole later used the passage or whether a shrew is hunting in it. Photograph the ridge and the surrounding vegetation before filling, flattening, or mowing it away.
Surface trails and gnawing point toward voles
Voles make or use narrow surface trails through grass and low vegetation. Look for those trails alongside gnawed bark or damage to roots, bulbs, and other plant material. Voles eat grasses, seeds, roots, bulbs, and other vegetation directly, so plant feeding paired with surface trails is more suggestive of voles than a mound alone.
Inspect more than one plant. Repeated damage along a runway is stronger evidence than a single wilted plant beside a tunnel. Examine stems, bark, exposed roots, bulbs, and the soil surface for signs of gnawing. If the only evidence is a displaced ridge, keep the conclusion limited to “digging is occurring” rather than “a mole ate the roots.”
A tunnel by itself is inconclusive
Shrews often use tunnels made by moles or voles instead of creating conspicuous surface tunnels of their own. Voles may also travel through mole runways. As a result, finding a tunnel does not establish which animal made it, used it, or caused nearby damage. The National Institute of Environmental Health Sciences overview and Penn State Extension’s vole guide describe these overlapping signs and habits.

This is why a tunnel should be treated as context, not a diagnosis. Combine it with the animal’s visible anatomy, the location of the runway, and the type of plant damage. A shrew can be present in a mole- or vole-made passage without being responsible for the mound or gnawed plant. Likewise, a vole can use a mole runway and leave feeding evidence nearby.
Reading the habitat without overinterpreting it
Location helps you organize clues, but it cannot replace them. An underground ridge in a lawn, a narrow path through low vegetation, and damage to a planted bulb each tell a different part of the story. Record whether the sign is above or below ground, whether soil has been pushed up, and whether vegetation has been clipped or gnawed. Note the habitat—lawn, garden bed, wooded edge, or another setting—when you contact a local authority.
Do not assume that the animal nearest the damage made every visible feature. Small mammals can share space and reuse passages. A mole may create the runway, a vole may travel it and feed on bulbs, and a shrew may hunt within it. The most reliable conclusion may be that more than one animal is using the same area.
Rank #3
What to do when plants are damaged
Separate the evidence of digging from evidence of feeding. Moles can affect roots by tunneling, but the available descriptions identify invertebrates—not roots or bulbs—as their primary food. Voles directly consume roots, bulbs, bark, seeds, grasses, and other plant material. A mound near a damaged plant does not, on its own, show that a mole ate it or even establish which animal caused the damage.
- Look for surface trails. Check the grass or low vegetation around the affected plant for a narrow runway. Trails combined with gnawing or plant feeding make a vole a more plausible explanation.
- Inspect the damage itself. Note whether there is evidence of gnawing or damage to roots, bulbs, or bark. These are consistent with vole feeding; subsurface ridges or loosened-soil mounds instead indicate digging activity.
- Keep tunnel evidence in context. A tunnel can be shared or reused. Do not assign responsibility from a runway alone.
- Photograph before disturbing the site. Include a scale, such as a ruler or coin, and take wider images showing how the damage relates to nearby ridges, trails, and vegetation.
- Record location and habitat. Write down where the sign occurred and what plants or ground cover were present. Regional species differences matter.
- Seek local identification if the clues disagree. A local extension office or wildlife agency can interpret evidence in light of the species found in your area.
Management depends on identifying the animal first. Oregon State University Extension wildlife specialist Dana Sanchez put it this way: “How you deal with them depends on what you have.” The statement appears in the university’s Oregon-focused guide to identifying and managing moles, voles, and gophers in gardens; it is a useful reminder that a management response should not be chosen from a tunnel or mound alone. See Oregon State University Extension’s guide.
A practical photo and observation checklist
If the animal is visible, observe from a safe distance and avoid handling it. Try to capture the side of the head, the front feet, the whole body, and the surrounding ground. A single close-up of a pointed snout may not show the traits needed for identification. Include a familiar object for scale and, if possible, take a second photograph of the sign in its wider setting.
- Is the body compact and velvety, very small with a pointed snout, or mouse-like with a blunt face?
- Are the forefeet broad and clawed, or small and ordinary-looking?
- Are the eyes and ears concealed, tiny, or clearly visible?
- Can you see prominent front incisors?
- Is the sign a subsurface ridge, a loose-soil mound, a surface runway, gnawed bark, or damaged roots and bulbs?
- Could another animal have made or reused the tunnel?
Send the notes and images to a local extension office or wildlife agency when you need a species-level answer. Mention the date, general location, habitat, and whether the animal was seen above or below ground. Regional experts can account for local species that a general comparison cannot distinguish.
Common identification mistakes
- Calling every small, pointed-nosed mammal a shrew: Check feet, body shape, and eyes as well as the snout.
- Calling a mole blind: Its eyes are small and concealed in fur; that is the useful field clue.
- Assuming a mole eats roots because a plant wilted: Moles mainly eat soil invertebrates. Their tunneling may physically disturb roots, which is different from feeding on them.
- Identifying the maker from a hole or tunnel alone: Several small mammals can share or reuse tunnels.
- Treating a general size range as a universal rule: The cited shrew and vole lengths are approximate descriptions from a Pennsylvania-focused guide, and local species differ.
- Confusing a runway user with a runway maker: A vole or shrew may use a passage first made by a mole.
- Choosing a control method before confirming the animal: Signs overlap, and management depends on what species is present and what damage is occurring.
- Relying on one damaged plant: Look for a repeated pattern of trails, gnawing, or root and bulb damage before drawing a conclusion.
When you need a species-level answer
The clues here distinguish the general groups; they do not identify every species. Penn State Extension’s guide is written for Pennsylvania, and the Oregon State Extension article is about Oregon gardens. Outside those regions, consult an extension office or wildlife agency serving your location, especially when the animal is not visible or signs conflict. Provide the location and habitat, a description of the feet and face if seen, and photos of the animal or damage when safely available.
A regional mammal field guide can be a useful optional aid when you cannot obtain a clear view, provided it covers the area where the animal was found. Use it to compare whole-body shape, feet, eyes, ears, and teeth rather than matching a single photograph. If the guide and the yard signs disagree, defer to local wildlife or extension personnel.

What is the simplest difference between a mole, shrew, and vole?
A mole is a digging specialist with broad, clawed forefeet. A shrew is a tiny pointed-snouted predator with small feet. A vole is a mouse-like plant-eating rodent with visible eyes and prominent front incisors.
Does a pointed nose prove that an animal is a shrew?
No. A pointed snout is an important shrew clue, but compare body size, feet, eyes, and overall shape. A single feature is not a reliable identification.
Are moles blind?
That wording is too categorical for field identification. The useful observation is that a mole’s eyes and ear openings are small and concealed in fur.

Moles primarily eat insects and other soil invertebrates, including worms. Their tunnels can disturb roots physically, but root disturbance is not the same as eating roots.
Can a shrew make the tunnel I found?
A shrew may travel through a tunnel made by a mole or vole rather than creating a conspicuous surface tunnel of its own. A tunnel alone cannot establish the maker or the user.
What does vole damage look like?
Look for narrow surface trails through grass or low vegetation combined with gnawing or feeding damage to bark, roots, bulbs, seeds, grasses, or other plant material. Those signs are more suggestive of voles than a soil mound alone.
Why is there a mole ridge beside a damaged bulb?
The ridge indicates digging, while the bulb damage indicates feeding or physical disturbance. A vole may be using a mole runway and eating the bulb, or tunneling may have disrupted roots. Inspect for surface trails and gnaw marks before assigning responsibility.
How can I tell the size ranges?
Penn State Extension gives approximate body lengths of 3–4 inches for shrews and 4–6 inches for voles in its December 15, 2025 guide. Treat those figures as general Pennsylvania descriptions, not universal limits for every species.

What should I do if the clues conflict?
Photograph the animal or sign with a scale if safe, record the location and habitat, and contact a local extension office or wildlife agency. Avoid selecting a management method until the animal and the type of damage are clearer.
Frequently Asked Questions
What is the quickest way to tell them apart?
Look at the forefeet first. Broad, clawed digging feet indicate a mole; small feet on a tiny pointed-snouted animal suggest a shrew; ordinary feet, a blunt face, visible eyes, and incisors suggest a vole.
Can I identify one from a tunnel alone?
No. Shrews and voles can use tunnels made by moles, and voles may use mole runways. Combine tunnel evidence with anatomy, surface trails, and feeding damage.

Voles directly eat roots, bulbs, bark, seeds, grasses, and other plant material. Moles mainly eat invertebrates, although their digging can disturb roots.
What should I send to an expert for identification?
Send photos with a scale, notes on the feet, face, eyes, ears, and teeth, plus the location, habitat, and details of any ridges, trails, gnawing, or plant damage.
The Bottom Line
Broad, clawed forefeet and underground ridges point to a mole; a tiny pointed snout with small feet points to a shrew; a mouse-like, blunt-faced animal with visible eyes and incisors points to a vole. Use several clues, because shared tunnels and overlapping yard signs make a single hole or ridge unreliable.
