Identifying Common animals that dig holes in lawns
Before you can stop the digging, you have to know who you are dealing with, as every animal has a unique “fingerprint” left in the soil. Some animals are looking for a snack, while others are trying to build a cozy home right under your feet.
Identifying animals that dig holes in lawns requires a bit of detective work, focusing on the size of the hole, the presence of loose soil, and the time of day the damage appears. Let’s look at the most frequent suspects you might encounter in your neighborhood.
The Subterranean Specialists: Moles
Moles are perhaps the most famous lawn excavators, but they are often misunderstood by homeowners who assume they are eating their plants. In reality, moles are insectivores that primarily hunt for earthworms and grubs deep within the soil profile.
You can identify mole activity by the presence of volcano-shaped mounds of soil, often called molehills, which they push up from their deep tunnels. They also create raised ridges or “runs” just below the surface that feel spongy when you step on them.
While their tunneling can aerate the soil, it also severs grass roots and creates an uneven surface that is difficult to mow. If you see mounds but no open holes, you likely have a mole patrolling your property.
The Tiny Terrors: Voles
Voles, often called meadow mice, are small rodents that can cause a surprising amount of damage in a very short period. Unlike moles, voles are herbivores and will happily munch on your grass blades, flower bulbs, and even the bark of young trees.
Voles create golf-ball-sized holes that are usually clean and clear of mounded soil, often located near the base of shrubs or in tall grass. They also leave behind “runways,” which are narrow paths of clipped grass that connect their various burrow entrances.
If you notice your perennials suddenly wilting or disappearing into the ground, voles are likely the ones responsible for the underground heist. They are active year-round and can be particularly destructive under the cover of winter snow.
The Nighttime Foragers: Skunks and Raccoons
If you wake up to find shallow, cone-shaped “divots” or patches of sod that have been flipped over, you aren’t looking at a burrower. Instead, you are dealing with nocturnal foragers like skunks and raccoons searching for a high-protein meal.
These animals are specifically looking for white grubs, which are the larvae of beetles that live just beneath the grass roots. They use their sharp claws to peel back the turf or dig small, messy holes to reach the tasty treats hidden below.
This type of damage is usually most prevalent in the late summer and early autumn when grubs are largest and closest to the surface. Fixing this issue usually starts with managing the insect population in your soil rather than the animals themselves.
Clues in the Dirt: Reading Your Landscape Like a Pro
To truly understand the behavior of animals that dig holes in lawns, you need to look at the physical evidence left behind. The shape and location of the hole can tell you more than a grainy trail camera photo ever could.
Start by measuring the diameter of the hole; a hole the size of a quarter suggests a large insect or a small rodent like a shrew. Holes that are 2 to 3 inches wide often belong to chipmunks or rats, while anything larger points toward groundhogs or skunks.
Check for the presence of a “plug” of soil, as some animals, like pocket gophers, will carefully seal their entrances to keep out predators. If the hole is wide open and surrounded by a fan-shaped mound of dirt, you are likely looking at a gopher’s back door.
Timing is also a critical clue in your investigation; check your lawn in the early morning to see if the dirt is still moist and fresh. Fresh excavations indicate that the animal is currently active, whereas dry, crusty soil suggests the resident may have moved on.
Natural and Humane Ways to Discourage Diggers
Once you’ve identified your visitor, it’s time to encourage them to find a new neighborhood using methods that are safe for your family and pets. I always recommend starting with habitat modification, which makes your yard less attractive to wildlife.
If skunks and raccoons are your problem, focus on eliminating their food source by applying milky spore or beneficial nematodes to kill lawn grubs. Without a steady supply of larvae to eat, these foragers will quickly move to a more productive hunting ground.
For moles and voles, castor oil-based repellents can be incredibly effective when applied correctly across the entire affected area. The oil coats their food sources and irritates their skin, causing them to seek out untreated soil elsewhere.
You can also use physical barriers, such as burying hardware cloth or fine wire mesh around the perimeter of your prize flower beds. Ensure the mesh extends at least 12 inches underground to prevent burrowers from simply diving under the fence.
Ultrasonic stakes are another popular option, though their effectiveness can vary depending on your soil density and the persistence of the animal. Many gardeners find that a combination of scent-based repellents and physical barriers works best.
Long-Term Prevention: Making Your Yard Less Inviting
Preventing animals that dig holes in lawns from returning is all about consistency and maintaining a healthy ecosystem. A thick, healthy lawn with deep roots is much more resilient to the occasional tunnel or dig than a stressed, thin lawn.
Keep your grass at a slightly higher height, around 3 inches, to discourage voles who prefer the cover of very short or very tall, matted grass. Regularly removing leaf litter and woodpiles also eliminates the hiding spots that chipmunks and shrews love.
If you have bird feeders, make sure to clean up spilled seeds daily, as these are a major attractant for rodents and the predators that follow them. Consider switching to “no-mess” birdseed blends that don’t have shells or fillers that accumulate on the ground.
Ensure your trash cans have tight-fitting lids and avoid leaving pet food outside overnight, which can draw in raccoons from miles away. By removing these easy “snacks,” you force the animals to look for more natural, less disruptive food sources.
Repairing the Damage and Restoring Your Grass
After the animals have vacated the premises, it’s time to roll up your sleeves and get your turf back into shape. Don’t just kick the dirt back into the hole; this often leaves air pockets that can cause future sinkholes.
For deep tunnels, use a long stick or a piece of rebar to collapse the tunnel as much as possible before filling it. Use a mixture of topsoil and sand to fill the void, tamping it down firmly with your foot as you go to ensure stability.
Once the hole is level with the surrounding ground, sprinkle a high-quality grass seed that matches your existing lawn type. Lightly rake the seed into the soil and cover it with a thin layer of peat moss or straw to keep it moist during germination.
Water the newly seeded areas lightly every day until the grass is about two inches tall, then transition back to your regular watering schedule. With a little patience, those unsightly brown patches will blend back into a seamless green carpet.
When to Seek Professional Help for Wildlife Issues
There are times when a DIY approach might not be enough, especially if you are dealing with large, aggressive, or protected species. If you find a massive hole that looks like it could belong to a badger or a groundhog, caution is your best friend.
Groundhogs, also known as woodchucks, can undermine the structural integrity of sheds, decks, and even home foundations with their extensive burrowing. If you suspect a burrow is located near a building, it’s time to call a professional wildlife relocation service.
In some regions, certain animals like armadillos or specific types of ground squirrels are protected by local or state laws. A licensed professional will know the legal requirements for trapping and relocating these animals safely and humanely.
If you feel overwhelmed or if the damage is occurring faster than you can repair it, don’t hesitate to reach out to a local pest control expert. They can provide a comprehensive assessment and offer solutions that might not be available to the general public.
Frequently Asked Questions About animals that dig holes in lawns
Are the holes in my lawn dangerous for my family?
While most holes are just an eyesore, they can present a tripping hazard, especially for children or elderly family members. Deep tunnels can also collapse under the weight of a person or a lawnmower, potentially causing ankle injuries or equipment damage.
Can I use coffee grounds to stop animals from digging?
Some gardeners find success using coffee grounds as a mild repellent due to their strong scent and abrasive texture. While they are a great soil amendment, they are rarely a complete solution on their own and should be used alongside other deterrents.
How do I know if the digging is caused by an insect?
Insect holes, such as those made by cicada killers or earthworms, are typically very small and surrounded by a fine, granular mound of soil. If the hole is less than an inch wide and perfectly round, you are likely looking at a beneficial insect rather than a mammal.
Is it true that chewing gum can kill moles?
This is a common gardening myth that has no scientific basis and can actually harm other wildlife or your pets. It is much more effective to use proven methods like castor oil repellents or professional trapping if the infestation is severe.
Will my lawn recover on its own from digging damage?
Most lawns can recover from minor digging, but the process is much faster if you intervene by filling the holes and overseeding. Leaving holes open allows weeds to take root and can lead to further soil erosion during heavy rainstorms.
Conclusion
Dealing with the various animals that dig holes in lawns is simply part of the journey of being a homeowner and a gardener. While it can be stressful to see your hard work disrupted, remember that your yard is a living ecosystem that supports many forms of life.
By taking a methodical approach—identifying the visitor, removing their motivation to stay, and repairing the damage—you can maintain a stunning landscape. Always prioritize humane and environmentally friendly solutions to keep your garden safe for everyone.
Stay observant, keep your soil healthy, and don’t be afraid to try different strategies until you find what works for your specific patch of earth. You’ve got this, and your lawn will be back to its lush, green self in no time at all!
