How to Manage Vole and Mole Problems in Your Yard and Food Forest Garden Beds
When it comes to maintaining a healthy yard or food forest garden, pests like voles and moles can quickly disrupt your hard work. These often-misunderstood animals might seem small and insignificant, but their damage to plants, soil, and roots can escalate if left unchecked. That said, managing vole and mole populations effectively doesn’t mean disrupting the surrounding ecosystem. A balanced approach allows you to protect your garden while supporting the broader environment.
This guide will walk you through everything you need to know about identifying, preventing, and controlling vole and mole problems. Let’s dig in.

Understanding the Difference: Voles vs. Moles
Before tackling the issue, it’s important to understand what you’re dealing with. While voles and moles both burrow and cause disruption, their behaviors and diets differ significantly. Misidentifying them could lead to ineffective management strategies.
Voles
Voles are small rodents (similar to field mice) that wreak havoc by chewing on plant roots, bulbs, and bark. Here’s how to identify vole activity in your yard:
- Vole trails: Look for shallow, visible paths in grass or mulch that create a “runway” system.
- Chewed bark: Evidence of chewing on the base of trees or shrubs.
- Missing plants: Plants may disappear altogether, often pulled underground by hungry voles.
Moles
Contrary to popular belief, moles aren’t rodents—they’re insectivores. They feed primarily on earthworms, grubs, and other soil-dwelling insects. Though they don’t eat plants, their tunneling behavior can inadvertently disturb plant roots and soil structure. Signs of mole activity include:
- Tunnels: Raised ridges or mounds of soil indicate mole digging.
- Uneven ground: Soil feels loose or spongy when you walk on it.
By distinguishing between these two pests, you’ll be better equipped to implement strategies that address their specific behaviors.
Preventative Strategies to Deter Voles and Moles
Taking preventative measures can help fend off voles and moles before they become a major issue. Here are three effective methods to keep them at bay:
1. Habitat Modification
Creating an unwelcoming environment is one of the simplest ways to deter voles and moles. Start by adjusting their surroundings.
- Reduce mulch depth around garden beds and trees, as voles love to nest in thick mulch.
- Keep the grass trimmed and remove dense vegetation where voles often hide.
- Avoid overwatering, as moist soil attracts earthworms, a primary food source for moles.
2. Physical Barriers & Exclusion Methods
Barriers can prevent voles and moles from accessing vulnerable areas.
- Surround young trees with hardware cloth or wire mesh (¼-inch openings). Ensure that the barrier extends at least 6 inches above ground and a few inches below.
- For garden beds, install raised beds with wire mesh bottoms to block burrowing.
- Bury perimeter fencing (at least 12 inches deep) to keep moles out of specific zones.
3. Encouraging Natural Predators
Nature can be your ally. By attracting predators, you can naturally manage vole populations.
- Install owl boxes to encourage barn owls or kestrels in your area.
- Allow snakes to roam your garden (only if they’re non-venomous and safe for your area).
- Keep a cat, which can help significantly with vole control (though consider potential environmental impacts of outdoor cats).
Control Methods for an Active Infestation
If preventative measures weren’t enough, it’s time to take direct action against voles and moles. Here are four effective control strategies:
1. Trapping for Voles and Moles
Trapping is one of the most humane and effective ways to reduce active populations.
- For voles, use snap traps baited with peanut butter, apple slices, or other appealing foods. Place traps directly in vole runways or burrow entrances.
- For moles, scissor-jaw or harpoon-style traps placed in active tunnels are effective. Check traps frequently and reposition if necessary.
2. Repellents and Deterrents
Repellents drive moles and voles away without harming them.
- Use castor oil-based repellents to humanely deter moles. Mix castor oil concentrate with dish soap and apply it using a hose-end sprayer. Work in sections, gradually driving the moles away from the area you want to protect. A few well-placed sprays can effectively and safely guide them out away from your property.
- Use natural scents like garlic, peppermint oil, or hot pepper spray to deter voles from specific areas.
- Predator urine (such as fox or coyote) can be placed near vole infestation zones.
3. Companion Planting & Repellent Plants
Strategic planting around your food forest beds can help deter pests naturally.
- Daffodils, marigolds, and alliums repel voles with their strong scents.
- Mole plant (Euphorbia lathyris) acts as a natural deterrent for moles.
4. DIY & Home Remedies
Some simple, homegrown solutions can keep small infestations from growing.
- Flood mole tunnels with water (though this offers only temporary relief).
- Spread coffee grounds, crushed oyster shells, or sharp sand near plants to discourage voles.
- Install vibrating stakes or ultrasonic repellents (with mixed success rates depending on soil conditions).
Protect Your Garden While Preserving Nature
The key to managing voles and moles is striking a balance between protecting your garden and maintaining its natural ecosystem. With prevention, strategic barriers, and effective control measures, you can create a healthy and productive yard or food forest.
