How To Get Rid Of Voles In My Lawn: Effective Control & Prevention

Can you get rid of voles in your lawn permanently? While complete eradication can be challenging, you can significantly reduce vole populations and prevent future infestations through a combination of control methods and proactive preventative measures. What is a vole? Voles are small, rodent-like mammals, often mistaken for mice or even moles, but they have distinct characteristics and cause different types of lawn damage.

Deciphering the Vole Problem: Identifying Vole Damage

Before you can effectively combat a vole issue, you need to be sure you’re dealing with voles and not another common garden pest. Identifying voles and the signs of their presence is the crucial first step in any successful vole control strategy.

Distinguishing Between Moles and Voles

It’s a common point of confusion: mole vs vole. While both can tunnel under your lawn, their motives and damage are different.

• Moles: Moles are insectivores. They tunnel in search of grubs, worms, and other invertebrates. Their tunnels are typically raised ridges of soil on the surface of your lawn, and they often create conical mounds of excavated soil, much like small volcanoes. Moles don’t typically eat plants.
• Voles: Voles, on the other hand, are herbivores. They feed on grasses, roots, bulbs, stems, and bark. Their activity is characterized by shallow, surface-level runways or pathways through the grass, often about 1-2 inches wide. These runways look like well-worn trails, especially in thicker grass. You’ll also see small, golf-ball-sized holes leading to their underground burrows. Vole damage often appears as chewed-off plants at or near ground level, girdled tree trunks (bark stripped around the base), and damaged bulbs.

Signs of Vole Infestation

Look for these telltale signs to confirm a vole infestation:

• Runways: These are the most common indicators. You’ll see distinct, matted-down pathways through your grass, especially in areas where the grass is longer or thicker.
• Small Holes: Scattered throughout the lawn and along the runways, you’ll find small, golf-ball-sized openings, which are the entrances to their burrow systems.
• Chewed Vegetation: Plants, flowers, and vegetables may appear nibbled or completely cut off at the base. They have a preference for tender new growth.
• Girdled Trees and Shrubs: Voles gnaw on the bark at the base of young trees and shrubs, often all the way around. This girdling can kill the plant by cutting off its nutrient and water supply.
• Bulb Damage: If you’ve planted bulbs, voles are notorious for digging them up and eating them. You might find evidence of tunnels near your bulb plantings.
• Droppings: Vole droppings are small, oval, and greenish-brown, often found near their runways or burrow entrances.

Effective Vole Control Methods

Once you’ve confirmed a vole infestation, it’s time to implement strategies for vole control. A multi-pronged approach is usually the most effective for tackling a vole infestation.

Trapping Voles

Vole traps are a direct and often effective method for reducing vole populations. The key is to place them correctly.

• Types of Vole Traps:
  • Snap Traps: These are similar to mouse traps but may need to be slightly larger or more sensitive for voles. They work by snapping shut on the vole when it triggers the bait.
  • Live Traps: These traps capture voles without harming them, allowing for relocation. However, relocation can be problematic, as you may just be moving the problem elsewhere, and relocated voles often don’t survive in unfamiliar territory.
• Placement is Key:
  • Along Runways: Place traps directly in the active vole runways. If you see a well-worn path, that’s a prime location.
  • Near Burrow Entrances: Position traps near the small holes that lead into their burrow systems.
  • Camouflage: Cover the traps with grass clippings, leaves, or soil to make them look like a natural part of the environment. Voles are naturally cautious.
• Baiting:
  • Preferred Foods: Voles are herbivores, so use baits that mimic their diet. Peanut butter, apple slices, oats, or sunflower seeds are good options.
  • Bait Placement: Place a small amount of bait on the trigger plate and a little bit leading up to the trap to lure the vole inside.
• Check Traps Regularly: Check your traps at least once or twice a day. Dispose of captured voles humanely and promptly.

Vole Extermination and Repellents

When traps alone aren’t enough, or for a broader approach to vole extermination, consider other methods.

• Repellents:
  • Castor Oil-Based Repellents: Many commercial repellents use castor oil as their active ingredient. These are designed to make the soil and vegetation unpalatable and irritating to voles. They work by disrupting their digestive systems.
  • Predator Urine: Repellents containing the scent of natural predators like foxes or coyotes can deter voles.
  • Natural Vole Repellent Options:
    • Mothballs (Naphthalene): While sometimes suggested, mothballs are toxic and can be harmful to pets, children, and beneficial soil organisms. Their effectiveness is also debated. Use with extreme caution and consider safer alternatives.
    • Peppermint Oil: Some anecdotal evidence suggests that the strong scent of peppermint oil can deter voles. You can soak cotton balls in peppermint oil and place them in and around runways and burrows.
    • Garlic and Chili Powder: Similar to peppermint oil, the strong smell and taste of garlic and chili powder might deter voles. Sprinkle them around affected areas.
• Rodenticides (Use with Caution): Rodenticides, or poison baits, are available for vole control. However, they come with significant risks:
  • Secondary Poisoning: Pets or wildlife that consume a poisoned vole can also be poisoned.
  • Environmental Impact: Rodenticides can contaminate soil and water.
  • Non-Target Species: They can harm beneficial insects and other wildlife.
  • Always follow label instructions precisely and consider them a last resort, especially if you have pets or children.

Habitat Modification for Vole Control

Making your lawn less appealing to voles can be a powerful long-term strategy for vole control.

• Mow Regularly: Keep your grass mowed to a shorter length. Voles prefer tall grass for cover and nesting.
• Remove Debris: Clear away fallen leaves, grass clippings, mulch piles, and other debris where voles can hide and build nests.
• Trim Vegetation: Keep the edges of your lawn and garden beds trimmed. Voles often use dense vegetation as a highway and a place to conceal their activity.
• Protect Trees and Shrubs: Install hardware cloth or plastic guards around the base of young trees and shrubs. Bury the guards at least a few inches into the ground and extend them up the trunk to at least 1-2 feet.

Introducing Natural Predators

Encouraging natural predators is a sustainable way to manage vole populations.

• Birds of Prey: Owls, hawks, and kestrels are natural predators of voles. Installing owl boxes or perching platforms can attract these birds to your yard.
• Snakes: While some may find them unwelcome, snakes are excellent vole predators.
• Domestic Cats and Dogs: While not always the most efficient hunters, some cats and dogs can help keep vole numbers down. Ensure your pets are safe and supervised.

Preventing Voles from Invading Your Lawn

Prevention is always better than cure. Implementing preventative measures can save you a lot of hassle and damage down the line.

Creating Barriers

Physical barriers are an excellent way to keep voles out of specific areas.

• Hardware Cloth Fencing: For garden beds or areas you want to protect, you can install a barrier of ½-inch or ¼-inch hardware cloth (wire mesh). Bury the cloth at least 6-12 inches deep and extend it 6-12 inches above ground level. Ensure there are no gaps where voles can enter.
• Root Protection: When planting bulbs or vulnerable plants, consider placing them inside a cage made of hardware cloth.

Maintaining a Healthy Lawn

A healthy, well-maintained lawn is less attractive to voles.

• Proper Mowing: As mentioned, keeping the grass short reduces cover.
• Weed Control: Remove weeds, especially those that voles favor.
• Proper Watering and Fertilization: A healthy lawn is more resilient to minor damage.

Sealing Burrow Entrances

Once you’ve dealt with an active vole infestation, it’s important to close up their burrows to prevent new ones from moving in. This is part of effective vole burrow removal.

• Fill Holes: Use soil, gravel, or even small rocks to fill in all the visible burrow entrances and runways.
• Compact the Soil: Pack the soil firmly to discourage re-excavation.

Vole Damage Repair

After you’ve managed the vole population, you’ll likely need to repair the damage they’ve caused.

• Repairing Runways: Simply rake over the damaged areas to level them out and encourage grass to grow back.
• Replacing Damaged Plants: If plants were completely destroyed, you’ll need to replace them.
• Treating Girdled Trees: For trees with minor bark damage, you can try applying a tree wound dressing. However, severe girdling often leads to the tree’s death. You may need to consider replacing severely damaged trees or shrubs.

Vole Control: A Seasonal Approach

The effectiveness of certain vole control methods can vary depending on the season.

• Spring: This is when voles are most active after winter and begin to reproduce. Early spring is a good time to set traps and apply repellents before populations surge.
• Summer: Voles continue to be active, but dense vegetation can make it harder to locate runways and place traps effectively. Focus on habitat modification.
• Fall: As temperatures cool, voles may become more aggressive in seeking food and shelter, potentially damaging plants and trees before winter. Fall is a critical time for preventative measures and clearing away leaf litter.
• Winter: While less active, voles may still tunnel under snow cover, damaging evergreen plants and tree bark. Keep protective barriers in place.

Frequently Asked Questions About Vole Control

Q1: How do I know if I have voles or moles?
A: Moles create raised tunnels and mounds of soil, feeding on insects. Voles create shallow, surface-level runways through grass and feed on plants, roots, and bark, leaving small, golf-ball-sized holes.

Q2: Are voles dangerous to humans or pets?
A: Voles are generally not aggressive towards humans or pets. However, like any wild rodent, they can potentially carry diseases. It’s best to avoid direct contact and keep pets supervised, as some pets might try to hunt them.

Q3: How long does it take to get rid of voles?
A: The time it takes to get rid of voles depends on the severity of the infestation and the methods used. With consistent trapping and habitat modification, you can see a significant reduction in population within a few weeks. Prevention is an ongoing effort.

Q4: Can I use ultrasonic repellers for voles?
A: The effectiveness of ultrasonic repellers for voles is highly debated and generally considered to be minimal. Voles are burrowing creatures and may not be significantly affected by sound waves transmitted through the soil.

Q5: What is the best time of year to deal with voles?
A: Early spring and late fall are generally the best times for active vole control measures like trapping and applying repellents, as populations are more manageable and their activity is often more apparent.

By combining identification, effective control methods, and consistent prevention, you can successfully manage and minimize vole damage in your lawn, restoring its health and beauty.
