What Are Moles and Why Do They Invade Lawns?
Moles are small burrowing mammals that can cause significant damage to lawns and gardens. They are commonly found throughout North America and Europe, and their feeding and tunneling activity can leave unsightly mounds of earth on the surface of lawns. Moles typically feed on insects and earthworms, which they locate using their highly sensitive sense of touch and smell.
Mole invasions can be frustrating for homeowners, as these creatures can quickly become a nuisance if not dealt with swiftly. One reason moles may invade lawns is due to the presence of their preferred food source: earthworms. Lawns with a high population of earthworms are likely to attract moles. Additionally, moist soil and thick grass provide an ideal environment for moles to tunnel and burrow.
It’s important to note that not all mole activity is detrimental to lawns and gardens. In fact, moles play an important role in ecosystem health, as their burrowing activity helps to aerate soil and distribute organic matter. However, when their activity becomes excessive, it can cause significant damage to lawn and plant roots.
There are several key signs that indicate mole activity on your lawn. These include raised mounds of earth, which indicate the location of burrows, as well as surface tunnels that may be visible on the surface of the lawn. It is important to monitor mole activity regularly in order to take preventative measures before damage occurs.
If you are dealing with a mole invasion, there are several natural methods for deterring moles that can help keep your lawn healthy and beautiful. These include using natural repellent plants such as garlic and marigolds, constructing underground fences, or using coffee grounds to exclude moles from your yard.

How Do Moles Damage Lawns?
Moles are burrowing rodents that live underground, feeding on insects and grubs in the soil. While they may not intentionally target your lawn and garden, their activities can cause serious damage to your outdoor space. Let’s take a look at how moles damage lawns:
| Type of Damage | Description |
|---|---|
| Tunnels | Moles dig tunnels just below the surface of the soil. This damages the roots of grass and plants and upends the soil, making it difficult for plants to grow properly. The tunnels can also create tripping hazards for people and pets. |
| Mounds | As moles dig their tunnels, they push up mounds of dirt that can be unsightly and get in the way of lawn maintenance. These mounds can also interfere with mowing and other activities on your lawn. |
| Drying Out of Soil | As moles dig tunnels and upend soil, they can cause soil to dry out more quickly, especially during hot and dry weather. The drying out of the soil can lead to plant damage and wilting. |
| Root Damage | Moles feed on insects and grubs that live in the soil, but they may also damage the roots of your lawn and garden plants in their quest for food. This can cause plants to die or become weakened. |
Preventing moles from invading your lawn is essential for maintaining a healthy outdoor space. In the next section, we will explore some proven methods for creating a mole barrier. You can also try using natural repellents such as garlic, marigolds, or coffee grounds to keep moles at bay.
Mole Barriers: Approaches and Best Practices
When it comes to protecting your lawn from mole damage, various approaches and best practices can be adopted to create mole barriers. These methods can range from physical barriers to landscaping techniques, chemical repellents, and natural deterrents. In this section, we will explore different strategies for deterring moles from invading your lawn, as well as the most effective practices for each approach. By implementing these methods, you can keep your lawn healthy and beautiful all year round. You can also use natural repellent plants, like those discussed in our previous section (using plant bulbs to make your lawn mole-free), as one of the mole barrier approaches.
Fencing and Netting Techniques for Keeping Moles Out
Fencing and Netting Techniques for Keeping Moles Out:
Fencing and netting techniques can be effective in keeping moles from invading and damaging lawns. Here are some strategies you can implement:
- Underground Fencing: One effective technique is installing an underground fence around problematic areas of the lawn. Dig a trench around the perimeter of the area and insert a metal barrier that extends at least two feet below the surface. This can be made from materials like galvanized hardware cloth or mesh wire. Cover the trench and you have a barrier that keeps moles out. For a step-by-step guide for an electric fencing system, consult with a professional.
- Netting: Netting is another effective technique that prevents moles from burrowing into the soil. However, it should be noted that netting needs to be installed prior to planting, as it can inhibit root growth. Simply cover the soil with a layer of netting and anchor it in place. The netting should be buried two inches below the surface and extend above the ground by at least a foot.
- Aluminum Foil: Some gardeners also swear by lining the perimeter of their gardens with aluminum foil to deter moles. To do this, simply attach sheets of foil to stakes and place them in the ground. The light will reflect off of the foil, confusing and scaring the moles away from the area. An additional benefit to this technique is that it will also ward off other pests like birds and rodents.
Remember to plan carefully where to place your barriers and take the time to install them correctly. This will help ensure their long-term effectiveness in keeping pesky moles from harming your lawn.
Landscaping and Garden Design Strategies for Preventing Mole Damage
Creating a mole barrier can be done through various approaches including landscaping and garden design strategies. These strategies can be implemented in a number of ways to prevent mole damage and keep them away from your lawn. Here are some tips on how to create a mole-resistant environment through landscaping and garden design:
| Tip | Description |
| Use Raised Beds | One of the best ways to keep moles out of your garden is to use raised beds. This method is highly effective as it creates an above-ground barrier that moles cannot dig through. |
| Plant Deep-Rooted Plants | Deep-rooted plants are more difficult for moles to displace as they have a more substantial root system. By planting such plants in your garden, you can create a more stable and lasting environment that will be less attractive to moles. |
| Install Pathways | Another effective way to prevent mole damage is to install pathways throughout your garden. Moles prefer to burrow in dark and undisturbed areas, and a well-lit area with foot traffic will discourage them from creating burrows in your garden. |
| Use Dense Ground Cover | Dense ground cover such as creeping phlox, ajuga, or potentilla can help to keep moles away by making it more difficult for them to dig through the soil. By covering the soil in your garden with such plants, you can deter moles from burrowing in your lawn. |
| Keep Soil Moist | Moist soil is more difficult for moles to dig through as it is denser and sticks together better. By keeping your soil moderately moist, you can make it harder for moles to create unsightly burrows throughout your lawn. |
| Remove Food Sources | Finally, it’s important to remove any food sources that may encourage moles to burrow in your lawn. This includes grubs, earthworms, and other small insects that moles feed on. By removing these food sources, you can make your lawn less appealing to moles. |
By incorporating these landscaping and garden design strategies, you can create a more mole-resistant lawn that requires less maintenance and is less prone to damage. Additionally, by taking a more preventative approach, you may be able to avoid the need for more invasive solutions such as chemical barriers or fencing.
