1. Understanding Why Animals Dig Holes
Animals dig holes in yards for a variety of reasons, most commonly in search of food, shelter, or nesting sites. Identifying the primary motivation behind the digging can help you determine the specific animal responsible and implement targeted solutions.
1.1. Seeking Food Sources
Many animals dig in search of food, such as insects, grubs, worms, and plant roots. Rodents like moles and gophers are particularly known for their digging habits as they forage for underground food sources.
To check if animals are digging for food, inspect your yard for grub infestations. Cut a 12-inch square of sod and peel it back to reveal the soil underneath. If grubs are present, you’ll see small, light-colored larvae wiggling in the soil. Treating your yard for grubs can significantly reduce the appeal to digging animals.
Earthworm infestations can also attract digging animals. Look for small, granular pellets of soil around pencil-sized holes, which are signs of earthworm activity. Rodents may be drawn to these areas in search of an easy meal.
Additionally, some animals feed directly on vegetation, including ornamental plants and vegetables. Signs of rodent predation, such as gnawing or girdling on plants, indicate that these animals are not only digging but also consuming your garden.
1.2. Creating Shelter
Animals like skunks often dig burrows for shelter, especially in moist, loose soil. These burrows serve as safe havens for living, breeding, and storing food.
If an animal is digging for shelter, you’ll likely find burrows near solid objects like your home’s foundation, patio, or fence lines. These areas provide additional protection and stability for their underground homes.
1.3. Building Nests
Many animals, including ground squirrels, moles, and voles, construct elaborate networks of underground tunnels that include nests for rearing their young.
These animals often establish nests in protected locations, such as under patios, decks, or near building foundations, with exit holes popping up throughout the yard.
2. Identifying Damage Caused by Burrowing Animals
Burrowing animals can cause a range of damage to your yard, from minor aesthetic issues to significant structural problems. Recognizing the specific type of damage can help you identify the responsible animal and implement appropriate control measures.
2.1. Soil Instability and Shifting
The extensive tunnel systems created by burrowing animals can undermine the soil, leading to erosion, instability, and shifting. This is particularly concerning when burrows are located near structures like sheds or your home’s foundation, as it can result in costly damage and repairs.
2.2. Grass Damage
Digging pests like raccoons, gophers, and voles are notorious for damaging grass. Voles create distinctive “runways” in the grass, while gophers tear up the grass, and raccoons pull up entire chunks of sod as they dig.
2.3. Dirt Mounds
Moles, gophers, and even earthworms create unsightly dirt mounds in the yard. These mounds can interfere with lawn mowing equipment and create tripping hazards.
2.4. Garden Damage
In addition to damaging grass and creating dirt mounds, digging animals often destroy flower and vegetable gardens. Young vegetation is especially vulnerable, and some animals may even pull entire plants into their burrows from below.
3. Identifying the Animals Digging Holes: A Comprehensive Guide
Identifying the animal digging holes in your yard is essential for implementing effective control measures. Here’s a detailed guide to help you identify common digging pests based on the size and characteristics of the holes they create.
3.1. Small Holes: Quarter to Softball Size
If you notice small holes ranging in size from a quarter to a softball, the culprit is likely one of the following animals:
3.1.1. Earthworms
Earthworms can create surprisingly large holes in the ground, typically surrounded by granular pellets of soil.
- Identification: Look for 1-inch-high piles of granular soil pellets around pencil-sized holes.
3.1.2. Cicada Killer Wasps
Cicada killer wasps dig small, U-shaped holes in well-drained, light soil, often near sidewalks, patios, or flower beds.
- Identification: Holes smaller than a quarter with a U-shaped entry channel.
3.1.3. Voles
Voles create distinctive runways in the grass, with small, round holes near concrete foundations and walkways.
- Identification: 1-2 inch paths on the surface of the turf, with neat, round holes ¾-2 inches across.
3.1.4. Pocket Gophers
Pocket gophers are known for causing extensive damage to yards, including digging, chewing electric wiring, and destroying sprinkler lines.
- Identification: Mounds of dirt near entry holes about 2-3 inches wide, with horseshoe-shaped fanning of the soil.
3.1.5. Eastern Chipmunks
Eastern chipmunks create holes slightly larger than a golf ball, connected to underground burrows.
- Identification: 2-3 inch diameter holes without mounding.
3.1.6. Ground Squirrels
Ground squirrels dig extensive networks of interconnected burrows, often beneath solid structures.
- Identification: 4-5 inch diameter holes with soil mounding, connected to underground burrows 2.5-4 feet deep and 5-35 feet long.
3.2. Large Holes: Larger Than a Softball
If you notice larger, more noticeable holes marked by large entrances or extensive mounding, the following animals may be responsible:
3.2.1. Moles
Moles create 2-inch diameter holes marked by conical mounds of soil and raised tunnels in the lawn.
- Identification: 2-inch diameter holes with conical mounds of soil and raised tunnels.
3.2.2. Norway Rats
Norway rats dig 2-3 inch diameter holes near foundations, gardens, and sheds, often clustering their holes near buildings or structures.
- Identification: 2-3 inch diameter holes connected to underground burrows, often near foundations and clustered together.
3.2.3. Skunks
Skunks dig cone-shaped holes in search of food, often digging at night.
- Identification: 3-4 inch diameter cone-shaped holes surrounded by a ring of loose soil, often under foundations, buildings, and porches.
3.2.4. Raccoons
Raccoons do not build underground burrows but dig in search of food, leaving behind chunks of sod that have been pulled out and flipped over.
- Identification: Cone-shaped, shallow holes about 3-4 inches in diameter with chunks of sod pulled out and flipped over.
3.2.5. Groundhogs
Groundhog holes are larger than softballs, about 10-12 inches wide, with a crescent-shaped mound of dirt.
- Identification: Holes larger than softballs, about 10-12 inches wide, with a crescent-shaped mound of dirt.
3.2.6. Snakes
Snakes do not dig their own burrows but use old rodent nests, burrows, and holes.
- Identification: Look for droppings with white ends or shed snakeskin near abandoned rodent burrows.
4. Strategies to Stop Animals from Digging Holes
Once you’ve identified the animal responsible for digging holes in your yard, you can implement targeted strategies to stop them. Here are some effective methods for controlling common digging pests:
4.1. Earthworms
Earthworms are generally beneficial for your lawn, providing natural aeration and fertilizer. Therefore, eliminating them is not typically recommended. However, if earthworm activity is bothersome, focus on habitat modification:
- Adjust your watering routine to provide 1-1.5 inches of water per week.
- Use a dethatcher to remove thatch buildup from your lawn.
- Manually remove worms that surface after heavy rainstorms.
- Introduce natural predators like birds.
- Reduce soil amendments like compost topdressing.
4.2. Cicada Killer Wasps
Cicada killer wasps are unlikely to sting, so homeowners can usually remove them safely by applying insecticidal dust around burrow entrances. Choose an insecticide containing Cypermethrin for the most comprehensive results.
4.3. Voles
A combination of approaches is recommended for eliminating voles:
- Remove vegetation and use mesh or plastic tubing to protect the trunks of young trees.
- Use humane, conventional removal methods like chemical vole repellents and traps.
4.4. Pocket Gophers
A comprehensive approach is necessary to stop pocket gophers:
- Install exclusion fencing made from wire mesh with openings of less than ½” x 1” to protect vulnerable areas.
- Remove weeds from the borders of your garden and yard.
- Install gopher wire in the bottom of your garden beds and plant trees and vegetables in wire gopher baskets.
- Use trapping and baiting to suppress gopher populations.
4.5. Eastern Chipmunks
Use the same habitat modification tactics as with gophers and voles. Baiting with treated grain can be effective during the summer and fall, and burrow fumigation is excellent during the spring. Destroy old burrows using a ripping bar to prevent re-infestation.
4.6. Ground Squirrels
Combine cultural and biological control methods:
- Modify the habitat by removing rocks, wood piles, and debris piles, and plow deep lines along the perimeters of your fences.
- Establish a trapping program.
- Use baits effective at eradicating ground squirrels, such as zinc phosphide and anticoagulants.
- Use fumigants in the early spring.
4.7. Moles
Start by removing their food sources:
- Use beneficial nematodes or milky spore to kill grubs without harming your yard.
- Dig trenches 2 feet deep and 6 inches wide around the area you want to protect.
- Avoid over-watering your lawn, limiting watering to about 1 inch per week.
- Employ a trapping program.
- Use mole baits.
4.8. Norway Rats
Modify the habitat by removing debris piles and food sources. Pay special attention to snail populations. Employ a trapping program to kill rats immediately and follow up with a long-term baiting strategy to prevent re-infestation.
4.9. Skunks
Focus on habitat modification. Install a motion-activated flood light to scare skunks away. If that doesn’t work, contact a professional pest management company for a humane trapping program.
4.10. Raccoons
Remove food sources by securing trash cans, installing exclusion fencing around gardens, and removing access to water sources. Treat your yard for grubs and install motion-activated lights and sprinklers.
4.11. Groundhogs
Contact a professional pest management company for help with a humane trapping program. Habitat modification, baiting, and repellents may also help.
4.12. Snakes
Prevent them from inhabiting abandoned rodent burrows by eliminating food sources like rodents, lizards, slugs, and small birds, removing standing water, and eliminating shelter like debris piles, leaf buildup, and wood piles.
