Burrowing Pests are animals and insects that dig, tunnel, nest, or feed beneath the soil, lawns, gardens, foundations, agricultural fields, and landscaped areas. This broad pest group includes moles, gophers, ground squirrels, voles, chipmunks, prairie dogs, ants, termites, ground-nesting wasps, mole crickets, and soil-dwelling beetle larvae. While underground activity is natural and often beneficial to soil ecosystems, excessive burrowing can damage turf, destroy plant roots, undermine hardscaping, create livestock hazards, and occasionally threaten structures.

Because many burrowing pests remain hidden for most of their lives, homeowners often notice the damage before they see the animal or insect responsible. Correct identification is especially important because a raised mole tunnel requires a completely different management strategy from a pocket gopher mound, fire ant colony, termite infestation, or lawn damaged by white grubs.

What Are Burrowing Pests?

Burrowing pests include species that spend all or a significant portion of their life cycle underground. Some construct permanent tunnel systems containing nesting and food-storage chambers, while others temporarily enter the soil to feed, reproduce, pupate, or escape predators and extreme temperatures.

Common burrowing pests found around homes, landscapes, farms, and commercial properties include:

Moles – insect-eating mammals that create raised surface tunnels while searching for earthworms and soil insects.
Pocket Gophers – plant-feeding rodents that construct extensive underground tunnel systems and characteristic soil mounds.
Voles – small rodents that create shallow burrows and surface runways while feeding on grasses, roots, bulbs, and bark.
Chipmunks – small striped rodents capable of digging burrows beneath patios, porches, retaining walls, and landscaping.
Ground Squirrels – colonial rodents whose extensive burrows can damage landscapes, fields, embankments, and structures.
Prairie Dogs – social rodents that construct large underground colonies containing interconnected tunnels and chambers.
Fire Ants – aggressive ants that establish extensive underground colonies beneath distinctive soil mounds.
Subterranean Termites – soil-dwelling insects that establish underground colonies and travel through concealed tunnels to reach structural wood.
Ground-Nesting Wasps and Yellowjackets – stinging insects that may occupy abandoned rodent burrows or excavate underground nests.
Mole Crickets – soil-dwelling insects that tunnel beneath turf while feeding on roots and other plant material.
White Grubs – scarab beetle larvae that live underground and consume turfgrass roots.

How to Identify Burrowing Pest Damage

The appearance of the soil disturbance is one of the best clues for identifying an underground pest. Tunnel shape, mound configuration, entrance-hole size, plant damage, and time of activity can help narrow down the culprit.

Raised Surface Ridges: Long, winding ridges across a lawn are strongly associated with mole activity.
Fan- or Crescent-Shaped Mounds: These commonly indicate pocket gophers, especially when no obvious open entrance is visible.
Open Burrow Holes: Larger entrances may indicate ground squirrels, chipmunks, rats, prairie dogs, or other burrowing rodents.
Loose Soil Mounds: Ants and some ground-nesting insects push excavated soil around their nest entrances.
Spongy Turf: Grass that pulls away easily from the soil may indicate root feeding by white grubs.
Collapsing or Yellow Turf: Mole crickets can loosen soil and damage roots beneath lawns.
Missing Plants or Bulbs: Pocket gophers, voles, chipmunks, and other rodents may consume underground plant material.
Mud Tubes on Foundations: Pencil-width earthen tubes traveling from soil toward structural wood can indicate subterranean termites.

Moles

Moles are among the most recognizable burrowing animals because their shallow feeding tunnels produce visible ridges across lawns. Contrary to a common misconception, moles are not rodents and generally do not eat grass roots. Their diet consists largely of earthworms, insects, and other soil invertebrates.

The primary problem is mechanical. Tunneling can separate turf roots from surrounding soil, disturb newly seeded areas, create uneven surfaces, and produce unsightly mounds. Moles may also indirectly damage gardens when their tunnels expose roots or provide pathways that other animals use.

Pocket Gophers

Pocket Gophers are considerably more destructive to plants because they are herbivorous rodents. They feed on roots, tubers, bulbs, and underground plant parts and may pull entire plants into their tunnels from below.

A single gopher can construct a surprisingly extensive burrow system. Their characteristic mounds are often fan-shaped or crescent-shaped, with the main entrance plugged with soil. Orchards, vegetable gardens, lawns, irrigation systems, and agricultural fields can all suffer damage.

Ground Squirrels, Chipmunks, and Prairie Dogs

Larger burrowing rodents can create problems extending beyond damaged vegetation. Ground squirrels, chipmunks, and prairie dogs excavate tunnels containing nesting chambers, escape routes, and food-storage areas.

Burrows located beneath patios, sidewalks, retaining walls, sheds, landscaping, and other improvements can contribute to soil displacement and settlement. Large colonies can also create holes hazardous to people, livestock, horses, and equipment.

Burrowing Insect Pests

Not every underground pest is a mammal. Some of the most economically important pests in the United States spend much of their lives beneath the soil.

Subterranean termites establish colonies underground and construct protective mud tubes that allow workers to travel between the soil and cellulose food sources. Unlike rodents, termites may cause serious structural damage without creating obvious surface burrows.

Fire ants create underground colonies containing extensive chambers and tunnels. Their mounds can interfere with lawns and agricultural operations, but their painful stings are generally a greater concern.

Mole crickets are specialized underground insects with enlarged front legs adapted for digging. Their tunneling loosens soil beneath turf, while feeding can damage grass roots and shoots. Heavy infestations may leave lawns thin, brown, and uneven.

Damage Caused by Burrowing Pests

Damage varies considerably according to species. Some burrowing animals are primarily nuisance pests, while others can cause substantial agricultural, landscape, or structural losses.

Lawn Damage: Tunnels and mounds create uneven turf and can interfere with mowing.
Root Feeding: Gophers, voles, white grubs, mole crickets, and other pests can damage plant root systems.
Crop Loss: Burrowing rodents may consume seeds, roots, bulbs, vegetables, and other crops.
Irrigation Damage: Rodents may damage buried irrigation tubing or interfere with drainage systems.
Hardscape Problems: Soil excavation beneath patios, walkways, retaining walls, and slabs can contribute to settling.
Stinging Hazards: Underground yellowjacket and fire ant colonies can create serious hazards in yards and recreational areas.
Structural Damage: Subterranean termites can attack wood components of homes and other buildings.

Management and Control

There is no universal treatment for Burrowing Pests. Effective control begins with identifying the species responsible before selecting a management method. Treating an unidentified burrow can waste time, harm beneficial wildlife, or create unnecessary pesticide exposure.

Inspect the Property

Examine mound shape, tunnel patterns, entrance size, droppings, tracks, damaged vegetation, and other signs. Monitoring with cameras can be useful when the animal is active at night or disappears whenever people approach.

Habitat Modification

Remove unnecessary brush, debris, spilled birdseed, accessible pet food, dense ground cover, and other resources that encourage rodents. Maintain vegetation around structures and repair locations where burrowing animals repeatedly gain shelter.

Physical Exclusion

Buried hardware cloth or other appropriate barriers can protect gardens, raised beds, sheds, and selected landscape features from certain burrowing animals. Barriers must extend sufficiently below ground to prevent pests from simply digging underneath them.

Trapping

Species-appropriate trapping can be effective for certain rodents and moles when permitted by state and local regulations. Correct placement is essential because traps generally need to intercept active tunnels or regular travel routes.

Professional Pest Control

Professional assistance may be appropriate when burrowing activity threatens a building, occurs across a large property, involves potentially dangerous stinging insects, or continues despite preventive measures. Suspected subterranean termite activity should receive particular attention because concealed structural damage can progress without obvious surface symptoms.

Beneficial Burrowing Animals

Burrowing does not automatically make an animal a pest. Many underground organisms provide important ecological benefits. Earthworms aerate soil and recycle organic matter, while numerous native insects and small mammals contribute to soil turnover, nutrient cycling, seed dispersal, and food webs.

Even animals considered pests in managed landscapes can play valuable ecological roles in natural environments. Management should therefore focus on situations where burrowing creates unacceptable property damage, agricultural losses, safety hazards, or structural risks rather than eliminating underground wildlife simply because it is present.

Preventing Burrowing Pest Problems

Regular property inspections can reveal developing problems before extensive tunnel systems become established. Watch for fresh soil, new holes, raised turf, disappearing plants, damaged irrigation components, and activity around foundations. Reducing food and shelter, protecting vulnerable garden areas, maintaining healthy turf, and addressing infestations early can substantially reduce long-term damage.

The most important rule is to identify before treating. Similar-looking holes can belong to completely different animals, and some burrows may even shelter beneficial or protected wildlife. Understanding what is living underground allows homeowners, landscapers, farmers, and pest professionals to choose a targeted Integrated Pest Management (IPM) strategy while avoiding unnecessary control.
