A row of seedlings disappears overnight. Fresh soil suddenly appears beside the lawn. A young tree has tooth marks around its trunk, or a vegetable plant seems to have been pulled straight underground. Garden damage like this is often blamed on “moles,” but moles are only one of many animals that dig, tunnel, burrow, or feed close to the soil.

Correct identification matters because the solution that works for a rabbit will do very little against a pocket gopher, and treating a lawn for insects will not solve a vole problem. Some animals are primarily eating plants, while others are searching for earthworms, grubs, rodents, or insects. A few may simply be using an existing burrow for shelter.

The most reliable approach is to identify the animal from its damage, protect the plants that matter most, remove unnecessary food and shelter, and use exclusion or legal control methods only where they are actually needed. Extension wildlife guidance consistently identifies barriers and exclusion as some of the most dependable long-term tools for protecting gardens.

Start With the Evidence: What Is Digging in Your Garden?

Before filling holes or buying repellents, look carefully at what has changed.

Raised ridges running just below the lawn usually point toward moles. Narrow trails through grass accompanied by gnawing on plants suggest voles. Fresh fan- or crescent-shaped soil mounds are more characteristic of pocket gophers. A large burrow entrance near a shed or garden with substantial vegetation missing may indicate a groundhog.

Cleanly clipped seedlings often indicate rabbits. Small holes near stone walls, foundations, or woodpiles may belong to chipmunks. Cone-shaped divots scattered through turf can result from animals such as armadillos or skunks searching for invertebrates.

Identifying the culprit first prevents a great deal of wasted effort.

1. Moles

Moles are frequently blamed for damaged vegetables, but they are insectivorous mammals rather than plant-eating rodents. They spend much of their time searching underground for earthworms and other soil invertebrates.

Their most recognizable signs are raised surface ridges and occasional mounds of loose soil. Tunneling can disturb roots or lift young plants, but moles generally are not eating the carrots, potatoes, bulbs, or tree bark that disappear from a garden.

The University of Minnesota Extension identifies trapping in active tunnels as the most effective direct method of mole control. Simply killing lawn grubs is not necessarily a solution because moles eat a variety of soil organisms, including earthworms.

A useful first step is to press down a short section of a raised tunnel and check it later. If the ridge is rebuilt, the run is probably active and is a better location for any control method permitted in your area.

2. Voles

Voles create very different damage even though homeowners often confuse them with moles.

These small rodents eat vegetation. They may feed on roots, grasses and garden plants and can gnaw bark around the base of trees and shrubs. Their activity is often revealed by narrow surface runways through grass rather than large piles of excavated soil.

Winter can be particularly troublesome because snow and dense vegetation give voles protected access to bark near ground level. Population numbers can also fluctuate considerably from year to year.

Good management starts with reducing heavy ground cover around vulnerable plants, keeping weeds and grass controlled, and protecting trunks with appropriately sized guards. Trapping is another option where legal and practical.

Do not pile thick mulch directly against young tree trunks. Dense cover around the base of a tree can give voles a protected feeding area.

3. Pocket Gophers

Pocket gophers are true underground plant eaters and can be among the most destructive animals in vegetable gardens.

They feed on roots and other vegetation, sometimes clipping plants from below. Their tunnels can also interfere with irrigation and create mounds that bury desirable plants.

Fresh soil mounds are one of the easiest clues. Pocket gophers generally maintain their own tunnel systems, so significant visible damage does not necessarily mean that dozens of animals are present. Utah State University Extension notes that, outside breeding periods and females with young, there is commonly one gopher occupying a tunnel system.

For raised beds and valuable garden areas, underground mesh is particularly useful. UC Integrated Pest Management and other extension guidance also identify trapping as a standard control option for active gopher systems.

4. Groundhogs, or Woodchucks

A groundhog is capable of eating far more garden vegetation than a mole or vole simply because it is a much larger animal.

Beans, leafy crops and other tender vegetation can attract groundhogs, and an established burrow may have a conspicuous entrance with excavated soil nearby. They can also climb surprisingly well, so a short, rigid fence may not be enough.

Penn State Extension identifies fencing as the most permanent method for reducing woodchuck damage. A commonly recommended design uses fencing at least about three feet high, with measures at ground level to prevent the animal from simply digging underneath.

Securing compost, harvesting ripe produce and removing easy food can help, but a hungry groundhog living next to a vegetable bed is unlikely to leave simply because a scent repellent has been applied.

5. Rabbits

Not every animal in this article spends most of its life underground. Rabbits are included because they use nests or burrows depending on the species and are among the most common garden raiders.

Typical rabbit damage appears above ground. Seedlings may be clipped, young growth disappears, and bark can be gnawed during periods when other food is scarce.

For gardens, exclusion is much more dependable than relying on supposedly rabbit-repellent flowers. Penn State Extension describes fencing as the most effective way to reduce cottontail damage, while Colorado State University notes that relatively low fencing with small openings and a buried lower edge can be effective.

Wire cages can also protect individual shrubs, young trees and prized plants without requiring the entire property to be enclosed.

6. Chipmunks

Chipmunks look harmless compared with groundhogs, but they can become persistent garden visitors.

They may dig up newly planted material, eat seeds, bulbs and fruit, and establish burrows near stone walls, patios, foundations, woodpiles and other sheltered locations. Penn State Extension specifically notes that chipmunks can dig up and nibble newly planted garden plants.

Removing spilled birdseed is often an overlooked step. A feeder that constantly scatters sunflower seeds around the garden can provide a reliable food source for chipmunks and other rodents.

For small plantings, physical protection is usually more realistic than trying to make an entire yard unattractive to them. Mesh around vulnerable beds and secure containers for bulbs, seed and animal food can substantially reduce opportunities.

7. Ground Squirrels

Ground squirrels are primarily a concern in regions where local species naturally occur, particularly open and relatively dry landscapes.

Unlike tree squirrels, they spend considerable time on or beneath the ground and create burrow systems. They can consume seedlings, seeds, vegetables and other vegetation while also digging around landscaped areas.

Damage can resemble that of chipmunks or pocket gophers, making identification from a single hole difficult. Look at the entire pattern: visible animals, burrow openings, tracks, chewed plants and the presence or absence of large soil mounds.

For small gardens, exclusion is usually the most practical starting point. If a large colony is involved, contact a local Cooperative Extension office or wildlife agency because legal control options vary considerably among species and locations.

8. Prairie Dogs

Prairie dogs are not a typical suburban backyard pest throughout North America. They are mainly relevant to parts of the Great Plains and western North America, particularly on larger rural or semi-rural properties.

Where colonies occur, the problem is much bigger than an occasional hole in a flower bed. Prairie dogs live in social colonies containing numerous burrows and can alter vegetation across a substantial area.

Because prairie dog management can involve wildlife regulations, land-use considerations and risks to other species, it should not be approached with random poison, smoke, or homemade treatments. Some control products are restricted, and local requirements can be significant. Extension guidance from Colorado, for example, emphasizes the need to check applicable wildlife and pesticide rules before control.

A large established colony is a situation where professional or agency guidance makes far more sense than general garden advice.

9. Armadillos

Gardeners in parts of the southern United States may wake up to multiple small excavations scattered across lawns and beds. The culprit can be a nine-banded armadillo.

Armadillos use powerful forefeet to dig for insects and other invertebrates near the soil surface. University of Georgia Extension describes the resulting holes as commonly several inches across and tapered downward. They can damage turf, flower beds and vegetable gardens despite not deliberately targeting most garden plants.

One common mistake is treating every insect in the lawn just to eliminate armadillo food. Oklahoma State University Extension cautions that this can also harm beneficial insects and may not solve an established armadillo problem.

For small beds, exclusion can work. Persistent animals may require wildlife-control assistance or locally permitted trapping.

10. Skunks

Skunks do not usually construct elaborate tunnel networks throughout a vegetable garden, but they may den underground and can produce extensive digging damage while searching for food.

Small pits appearing across turf can be caused by skunks feeding on grubs and other soil organisms. Their damage may therefore look similar to armadillo activity in areas where both animals occur.

If lawn digging coincides with a genuine white-grub infestation, treating the underlying turf problem with an appropriately labeled control can reduce the food attracting the animal. The important word is genuine: do not apply insecticides merely because an animal has dug a hole. Check the turf first. Penn State Extension lists skunks, moles and some birds among the animals whose feeding can indicate the presence of white grubs.

Secure garbage, pet food and accessible compost as well, since these can provide additional reasons for skunks to visit.

11. Badgers

Badgers are uncommon visitors to ordinary residential gardens, but they deserve mention on rural and large properties in regions where they naturally occur.

They are powerful digging predators. Instead of entering a garden primarily to eat lettuce or bulbs, a badger may excavate soil while pursuing rodents such as pocket gophers. Utah State University Extension notes that badger digging associated with gopher hunting can add to the damage caused by the gophers themselves.

This is not an animal to corner or attempt to capture casually.

If a large burrowing animal that may be a badger is repeatedly using an area near a home, livestock enclosure or garden, keep pets away and contact the appropriate local wildlife authority or qualified wildlife-control professional for guidance.

14 Ways to Protect a Garden From Burrowing and Digging Animals

There is no single treatment that works against every animal. The strongest strategy is usually a combination of identification, exclusion and changes to the conditions that are attracting the species.

1. Identify the Animal Before Treating Anything

This is the most valuable step.

Look at:

• hole diameter and shape
• whether loose soil is present
• whether tunnels create raised ridges
• tooth marks on bark
• clipped versus uprooted plants
• tracks and droppings
• time of day when damage appears
• nearby food, water and shelter

A trail camera can also be helpful when the damage occurs overnight.

Treating “something underground” without identifying it can easily make the problem worse or waste money.

2. Fence the Vegetable Garden

For above-ground feeders such as rabbits and groundhogs, fencing is one of the most consistently useful defenses.

The exact design should match the animal. Rabbits require relatively small mesh openings and protection against squeezing or digging beneath the bottom. Groundhogs require a stronger and taller barrier and may need additional protection at the bottom and top.

Do not assume one fence design works for every species.

3. Line Raised Beds With Wire Mesh

If pocket gophers or voles are entering beds from underneath, line the bottom of a new raised bed with durable, appropriately sized hardware cloth before adding soil.

This does not eliminate animals from the rest of the property, but it protects the part that matters most: the root zone of your crops.

Underground mesh barriers are specifically recommended for valuable plantings in pocket-gopher country.

Inspect the material periodically because buried metal eventually deteriorates.

4. Protect Young Trees Individually

A few dollars spent on a trunk guard can prevent serious vole or rabbit damage.

Use a suitable wire or commercial guard around vulnerable trees and shrubs while leaving room for growth. Check it regularly so it does not rub against or constrict the trunk.

In snowy climates, remember that animals may feed from the top of accumulated snow, effectively raising the height they can reach.

5. Reduce Dense Cover

Voles, rabbits, chipmunks and other small mammals benefit from vegetation and debris that allows them to move while remaining concealed.

Keep weeds under control around valuable beds. Avoid allowing thick grass to grow directly against tree trunks. Remove unnecessary boards, debris and abandoned piles near the garden.

Penn State and University of Minnesota Extension both recommend reducing vegetation and ground cover as part of vole management.

The goal is not to strip the landscape bare but to avoid creating protected highways directly into your crops.

6. Manage Mulch Carefully

Mulch is valuable for moisture conservation and weed suppression, but excessive mulch piled against plant stems and trunks creates sheltered space.

Leave breathing room around tree trunks and monitor heavily mulched areas for runways or burrow openings.

A moderate layer that serves the plants is preferable to a deep pile that inadvertently shelters rodents.

7. Remove Easy Food

Harvest vegetables instead of leaving overripe produce in the bed. Pick up fallen fruit. Secure garbage and compost containing food scraps. Bring pet food indoors.

Pay particular attention to bird feeders.

Birdseed scattered beneath a feeder can support chipmunks, mice, rats, squirrels and other animals you may not have intended to feed.

8. Use Barriers Around Individual Plants

You do not always need to fence an entire property.

Small wire cages can protect:

• seedlings
• berry bushes
• young fruit trees
• newly planted shrubs
• bulbs
• lettuce and other vulnerable greens

This is often cheaper and easier than attempting to eliminate every wild animal from a yard.

9. Confirm Active Tunnels Before Setting Controls

Old tunnels can remain visible long after an animal stops using them.

For moles, flattening a section of a surface run and later checking whether it has been repaired can help identify active travel routes.

For gophers, fresh mounds are better targets for investigation than old, weathered soil piles.

Targeting current activity makes any permitted trapping or exclusion work far more efficient.

10. Use Repellents Realistically

Wildlife repellents can sometimes reduce feeding, but they are not invisible fences.

Weather, hunger, available alternative foods and the animal itself all influence performance. Colorado State University notes that rabbit repellents can be inconsistent, and a product effective for one species should not automatically be assumed to work for another.

Use only products labeled for the animal and application you have in mind. Follow label directions rather than creating stronger homemade mixtures.

Extension pesticide guidance also cautions that repellents should be used only for their registered purposes and according to the label.

11. Try Motion-Activated Sprinklers for Surface Visitors

A motion-activated sprinkler can be useful against animals that repeatedly walk into the same garden entrance.

It provides an immediate disturbance without requiring poison or permanent noise.

Move the unit occasionally and combine it with exclusion whenever possible. Animals may become accustomed to deterrents if nothing actually prevents access to the food.

These devices are much more relevant to rabbits, groundhogs and similar surface visitors than to an animal living almost entirely underground.

12. Support Natural Predators Without Depending on Them

Owls, hawks, foxes, snakes and other predators naturally consume rodents, and healthy predator populations are an important part of the ecosystem.

Providing suitable habitat for native wildlife can contribute to natural population control, but it should not be treated as a guaranteed cure for an established infestation.

An owl box, for example, will not necessarily result in an owl moving in, nor will one owl eliminate every vole or gopher.

Avoid casually using rodenticides when predator protection is one of your goals, since poison can create risks for non-target wildlife.

13. Trap Only Where It Is Legal and Appropriate

Trapping can be highly effective for certain animals, particularly moles and pocket gophers.

But trapping laws, allowable devices, relocation rules and protected-species regulations vary.

Relocation is not automatically the humane option people assume it is. It may be illegal, and moving an animal into unfamiliar habitat can create welfare or disease-management problems.

Check state, provincial or local regulations before capturing or moving wildlife.

14. Call a Wildlife Professional When the Problem Is Beyond a Garden Fix

Some situations are not good DIY projects.

Get professional or wildlife-agency advice if:

• burrows are affecting a building or foundation
• a large animal has established a den beneath a structure
• you suspect a protected species
• a prairie dog colony covers a substantial property
• repeated exclusion has failed
• you cannot confidently identify the animal
• control would require restricted pesticides or fumigants
• an aggressive or potentially dangerous animal is involved

A qualified professional can identify the species and recommend methods that comply with local regulations.

Popular Burrowing-Animal Tricks That Often Disappoint

A surprising number of traditional garden remedies sound more reliable than they really are.

Ultrasonic stakes

Electronic and vibrating stakes are heavily marketed for moles and gophers, but consistent, dependable control should not be assumed. Established animals may tolerate or avoid the affected area temporarily without leaving the property.

Repellent plants

Daffodils, marigolds, garlic and other plants are frequently promoted as living barriers against everything from rabbits to moles. Plant preferences certainly vary, but a border of strongly scented flowers is not a substitute for physical exclusion around a valuable vegetable garden.

Flooding burrows

Putting a hose down a hole can waste large amounts of water, damage soil and simply send an animal to another entrance. Extensive tunnel systems may contain multiple exits and chambers.

It also creates a serious problem if you do not know what species occupies the burrow.

Filling every hole immediately

Never automatically seal an occupied den.

Young animals may be inside, and some burrows can be used by wildlife other than the species that originally dug them.

Removing all grubs to eliminate moles

Moles do eat soil insects, but they also eat earthworms and other invertebrates. University of Minnesota Extension recommends trapping active moles rather than treating grub control as the main solution.

Only treat lawn insects when those insects themselves have been identified as a pest requiring treatment.

A Special Case: Burrowing Owls Are Not Ordinary Garden Pests

Burrowing owls occasionally appear in discussions of “burrowing animals,” but they should not be handled like gophers or groundhogs.

These small owls often use burrows created by other animals and consume insects and small vertebrates. In the United States, burrowing owls are protected under the Migratory Bird Treaty Act. The U.S. Fish and Wildlife Service states that killing, capturing or otherwise taking protected migratory birds without authorization is prohibited.

If you discover what appears to be an occupied burrowing-owl nest, do not fill the entrance, trap the birds or attempt to move them yourself. Contact the appropriate wildlife agency for guidance.

The same principle applies to any wildlife you cannot confidently identify.

The Best Defense Is Usually a Layered One

A garden does not need to become a fortress, and eliminating every animal from a property is rarely realistic.

Instead, concentrate protection where the potential damage is greatest.

A vegetable garden may need a well-designed fence. A raised bed in gopher country may need wire mesh beneath it. Young trees may need trunk guards. Vole-prone areas benefit from vegetation management. A recurring groundhog may justify stronger exclusion, while a large or regulated wildlife problem may require professional help.

Start with the evidence instead of the animal you happen to suspect. Identify what is making the tunnels, mounds, clipped stems or shallow holes, then match the solution to that species.

That simple change—from fighting “burrowing pests” in general to solving a specific wildlife problem—is usually what makes garden protection more effective, safer and far less frustrating.
