You step into your garden in the morning, ready to enjoy your hard work, only to find chaos. Soil is scattered, plants are uprooted, and small holes pockmark your beds. It’s frustrating and confusing. If you’re wondering what is digging up my plants at night, you’re not alone. Nocturnal disturbances in your garden often point to a few common, hungry creatures.
This guide will help you identify the culprit and take effective action. We’ll cover the telltale signs of each animal, from the holes they leave to the plants they target. You’ll learn practical, humane methods to protect your garden and reclaim your peace.
What Is Digging Up My Plants At Night
Before you can stop the damage, you need to know who’s causing it. Different animals leave distinct evidence. The time of year, the size of the holes, and the type of plant damage are all critical clues. Let’s investigate the most likely suspects.
Common Nocturnal Garden Culprits
Several animals are active under the cover of darkness. Their feeding and foraging habits can disrupt even the most carefully tended garden.
Armadillos
Armadillos are notorious for their digging. They have powerful claws designed for rooting in soil. You’ll often find cone-shaped holes about 1-3 inches deep and 3-5 inches wide. They’re primarily searching for insects, grubs, and earthworms, but their digging can uproot plants and bulbs in the process. Their activity is most common in the southeastern United States.
Skunks
Skunks dig small, shallow holes in lawns and garden beds. They use their long claws to tear up sod or soft soil looking for grubs, their favorite food. The damage often looks like patches of peeled-back turf or small, funnel-shaped divots. While they might not eat your plants directly, their digging can sever roots and destroy seedlings overnight.
Raccoons
Raccoons are clever, dexterous, and messy. They might dig for earthworms or grubs, but they are also known to pull up young corn plants, roll up fresh sod looking for insects, and raid vegetable patches for ripe produce. Their hand-like paws can cause significant, widespread disturbance in a single night.
Moles And Voles
People often confuse these two, but their damage is different. Moles create raised ridges or tunnels in your lawn as they hunt for soil-dwelling insects. They rarely eat plants. Voles, however, are rodents. They create small, clean holes about 1.5 inches wide and leave well-defined surface runways through grass. They gnaw on plant roots, bulbs, and the bark of young trees, often causing plants to wilt and die.
Opossums
Opossums are more likely to be scavengers than dedicated diggers. They might rummage through soft soil for insects, slugs, or fallen fruit. Their digging is usually less destructive than an armadillo’s or skunk’s, but they can still disturb mulch and shallow-rooted plants while foraging.
Squirrels
Though diurnal, squirrels can bury and dig up nuts in garden beds, especially in fall and spring. This behavior creates small, random holes and can dislodge bulbs and small plants. They are also known to dig in potted plants on patios and decks.
How To Identify The Animal By The Damage
Look closely at the evidence left behind. The details will point you to the right pest.
- Large, deep holes (6+ inches wide): Could indicate a groundhog (woodchuck) or the entrance to a burrow. This is less common for simple nightly foraging.
- Cone-shaped holes 1-3 inches deep: Classic sign of an armadillo probing for insects.
- Small, shallow divots in the lawn: Likely a skunk or raccoon peeling back grass for grubs.
- Raised tunnels in the grass: Almost certainly the work of a mole.
- Neat, small holes with gnawed plants: Points to voles or other small rodents.
- Scattered soil and uprooted seedlings: Often raccoons, birds (like crows during the day), or even cats.
- Specific plants eaten: Raccoons love corn, skunks might dig for specific grubs under turf, and voles target root vegetables.
Immediate Steps To Take After Discovering Damage
When you first see the mess, a few quick actions can help you gather clues and prevent further loss.
- Document the Damage: Take photos in the morning light. Note the size and shape of holes, any tracks in soft soil, and which plants are affected.
- Check for Tracks: Smooth out a small area of disturbed soil. Sprinkle a light layer of flour or use sand. Check the next morning for footprints.
- Remove Attractants: Secure compost bins, pick up fallen fruit, and ensure garbage cans are tightly sealed. Eliminate easy food sources.
- Protect Vulnerable Plants: Temporarily cover prized plants with overturned baskets or weighted row covers at night until you implement a long-term solution.
Using A Trail Camera For Definitive Identification
If the culprit remains a mystery, a wildlife trail camera is your best investment. Set it up facing the damaged area at dusk. Modern cameras have night vision and motion sensors. You’ll have a clear photo or video of the animal within a night or two, confirming your suspicions and guiding your control strategy.
Effective, Humane Deterrents And Solutions
Once you know the animal, you can choose targeted methods. The goal is to make your garden less appealing, not to harm wildlife.
Physical Barriers And Fencing
This is often the most permanent solution.
- For Raised Beds: Attach hardware cloth (a stiff wire mesh) to the bottom of the bed frame before filling with soil to prevent digging from below.
- For Ground Beds: Bury hardware cloth or chicken wire at least 6-12 inches deep around the perimeter and bend the bottom outward to form an “L” shape. This stops burrowers.
- For Individual Plants: Use wire cloches or cylinders made of hardware cloth around young trees or valuable shrubs to protect stems and roots.
- Overhead Netting: Use bird netting secured tightly over berry bushes or small plots to deter raccoons and birds.
Repellents: Scent, Taste, And Motion
Repellents work by targeting an animal’s keen senses. They usually need reapplication after rain.
Commercial Repellents
Look for products containing putrescent egg solids, capsaicin (hot pepper), or garlic. These create an odor or taste barrier that mammals find offensive. Follow label instructions carefully and rotate products to prevent animals from becoming accustomed to one type.
Homemade Deterrents
- Spicy Spray: Mix 2 tablespoons of hot pepper sauce or cayenne pepper with a gallon of water and a few drops of dish soap (to help it stick). Spray on plant leaves and soil. Reapply after watering or rain.
- Predator Urine: Granules or liquids containing coyote or fox urine can be effective for deterring smaller prey animals like rabbits and voles. Place them around the garden perimeter.
- Soap and Hair: Some gardeners report success with placing strongly-scented bar soap (like Irish Spring) or bags of human/pet hair around the garden. The scent of humans or predators can be a warning.
Motion-Activated Devices
These startle animals with unexpected movement, light, or sound.
- Motion-activated sprinklers: Highly effective for many animals. The sudden burst of water frightens them without causing harm.
- Ultrasonic repellers: Emit a high-frequency sound unpleasant to pests but inaudible to most humans. Their effectiveness varies.
- Simple visual deterrents: Pinwheels, reflective tape, or old CDs hung on string can create flashes of light and movement that unsettle nocturnal visitors.
Long-Term Garden Management
Changing your garden’s environment can make it less attractive in the first place.
- Reduce Grub Populations: Since skunks and raccoons dig for grubs, treating your lawn with beneficial nematodes or milky spore powder can eliminate this food source over time.
- Keep It Tidy: Remove dense ground cover, piles of wood, or debris near the garden that can provide shelter for animals.
- Install Outdoor Lighting: Strategic, low-voltage solar lights can make a garden less inviting to creatures that prefer darkness.
- Get a Dog: The presence and scent of a dog patrolling the yard is one of the most effective natural deterrents for many garden pests.
Specific Strategies For Each Animal
Dealing With Armadillos
Armadillos are driven by their search for insects. Focus on removing their food supply and creating physical barriers.
- Apply a grub control treatment to your lawn and garden.
- Install a fence that extends at least 12 inches underground and 18 inches above, bending the top outward. They are poor climbers but excellent diggers.
- Use castor oil-based repellents on the soil, which can make insects and the soil itself taste bad to them.
Deterring Skunks
Skunks are relatively timid. The key is to address their grub hunting and use scent deterrents.
- Treat for lawn grubs in late summer or early fall.
- Place ammonia-soaked rags in cans (with holes punched in the lids) near digging sites. The strong smell often drives them away.
- Motion-activated lights or sprinklers are very effective against skunks.
Outsmarting Raccoons
Raccoons are intelligent and persistent. You need secure, physical solutions.
- Use secure, locking lids on all garbage and compost bins.
- Install electric fencing around sweet corn or vegetable patches. A single strand 6-8 inches off the ground can be very effective.
- Harvest ripe vegetables promptly, and pick up fallen fruit every evening.
Controlling Moles And Voles
For moles, reduce their food. For voles, use barriers and traps.
- For Moles: Apply insecticide for grubs and worms. Use castor oil granules as a repellent. Flooding or collapsing active tunnels can encourage them to move elsewhere.
- For Voles: Protect young trees with plastic or wire mesh guards. Set mouse traps baited with apple or peanut butter along their runways. Keep grass mowed short and remove mulch from directly around tree trunks to eliminate cover.
When To Call A Professional
Sometimes, the situation requires expert help. Consider calling a licensed wildlife control professional if:
- The animal has gotten into your home, attic, or under a structure.
- You suspect a large infestation, like a colony of voles.
- The animal appears sick or behaves aggressively (which is rare but possible, especially with raccoons).
- Your own efforts have failed, and the damage is severe or costly.
- Local laws protect the animal, and you need guidance on legal relocation methods.
A professional can offer safe, legal, and often more permanent exclusion techniques.
Preventing Future Nighttime Garden Raids
Consistency is crucial. A layered defense works best. Combine a few methods for reliable protection.
- Start with habitat modification each season: clean up, manage insects, and remove attractants.
- Install permanent barriers for high-value areas like vegetable gardens or new lawns.
- Use temporary repellents or deterrents during peak problem seasons, like when young animals are foraging in spring or when grubs are near the surface in fall.
- Be observant. Check your garden regularly for early signs of new activity so you can act quickly.
FAQ: What Is Digging Up My Plants At Night
What Animal Is Digging Small Holes In My Yard At Night?
The most common animals digging small holes at night are skunks, armadillos, and raccoons. Skunks make small, shallow divots for grubs. Armadillos create cone-shaped holes. Raccoons leave messy, scattered holes often near the base of plants.
How Do I Stop Animals From Digging Up My Plants?
Use a combination of methods. First, identify the animal. Then, employ physical barriers like buried fencing, use scent or taste repellents consistently, and consider motion-activated sprinklers. Reducing food sources like grubs is also a key long-term strategy.
Do Coffee Grounds Deter Animals From Digging?
Some gardeners find used coffee grounds can help deter slugs and cats due to their texture and scent. However, they are not a reliable deterrent for larger, determined pests like raccoons or armadillos. They are better used as a mild supplement to other, more robust methods.
What Makes Small Round Holes In The Soil Overnight?
Small, round holes are often made by squirrels digging for buried nuts or by birds like robins hunting for worms. Insects, such as solitary bees, can also create neat, round holes but they are typically very small and rarely damage plants significantly.
Will Vinegar Keep Animals From Digging?
Vinegar’s strong smell may temporarily repel some animals, but it dissipates quickly and washes away easily with rain or dew. It is not a long-lasting or highly effective solution compared to commercial repellents or physical barriers. It can also harm plant leaves if sprayed directly on them.
Figuring out what is digging up your plants at night takes a bit of detective work, but it’s a solvable problem. By carefully observing the damage, identifying the culprit, and implementing a persistent, multi-layered approach, you can protect your garden. Remember, the goal is coexistence—deterring animals humanely while enjoying the fruits (and vegetables) of your labor. With patience and the right tactics, you can restore order to your garden and sleep soundly knowing your plants are safe.
