Identifying Mole Damage
Mole damage can be very frustrating for gardeners, but before you can figure out how to prevent it, you need to make sure that the damage is actually caused by moles. Here are some signs that you have a mole problem:
|Signs of Mole Damage
|Mounds of soil:
|When moles dig tunnels, they push up mounds of soil as they go. These mounds can be larger than those made by other burrowing animals.
|Moles dig tunnels just below the surface of the soil, so if you see shallow grooves or ridges in your lawn or garden bed, it could be a sign of mole activity.
|Moles eat insects and grubs, but they can also damage plants by digging up their roots as they tunnel through the soil.
|If you see plants that are wilting for no apparent reason, it could be because their roots have been damaged by moles.
If you see any of these signs, it’s a good idea to take action to prevent further mole damage.

Understanding Mole Behavior
To create an effective mole barrier, it’s important to understand mole behavior and why they may be attracted to your garden. Moles are small burrowing mammals that typically live in underground tunnels. They are known for creating raised ridges or mounds in lawns and gardens, which can be unsightly and damage plant roots.
Here is a table outlining some key behaviors and preferences of moles:
|Have poor eyesight and rely on their sense of touch and smell to navigate and find food
|Feed primarily on insects, earthworms, and other small invertebrates found in soil
|Create complex networks of tunnels to forage and nest in, which can span large areas and cause damage to plant roots
|Prefer loose, moist soil with abundant prey, but can also live in sandy or heavy clay soils with less food availability
|May be deterred by certain plants, such as daffodils, alliums, and marigolds, that have natural pest-repelling properties (learn more about companion planting for mole prevention)
|May be deterred by certain ultrasonic sound frequencies, emitted by devices such as sonic mole repellents
By understanding mole behavior and preferences, you can better choose a mole barrier that will effectively keep them out of your garden. Depending on your specific situation, you may choose to use natural, chemical, or physical barriers (learn more about some options in the following section).

Protecting your garden from mole damage is essential to keep your outdoor space healthy and aesthetically pleasing. While there are various natural remedies and products that claim to deter moles, creating a physical barrier is often the most effective way to prevent their intrusion. In this section of the article, we’ll explore different mole barrier options that you can use to ensure your garden remains a lush paradise. Whether your garden is situated in clay soil or sandy loam soil type, or you want to keep the maintenance low with a simple physical barrier, we have you covered. So, let’s move on and find which type of barrier works best for your garden’s specific needs. Don’t forget to check our previous post on preventing mole damage tips to learn more about mole behavior and damage identification.
One way to create a mole barrier is to make use of natural barriers. Natural barriers are materials that are readily available in nature and are often more environmentally friendly than other options.
Here are some examples of natural barriers that can be used:
|Gravel or stones
|Allows for water drainage, can be attractive in landscaping
|May require frequent maintenance to keep moles from tunneling underneath
|Sharp objects like pine cones, holly leaves, or acorns
|Repels moles without harming them
|May get displaced by wind or rain
|Plants with strong scents, like alliums, marigolds, or daffodils
|Repels moles and adds to the beauty of the landscaping
|May not be as effective as other barriers if the plants are not in sufficient quantity
It is important to note that different soil types may require different natural barrier options. For example, clay soil may require a different approach than sandy soil. It is also important to monitor the effectiveness of the barrier and make changes as necessary.
Chemical barriers can be an effective way to deter moles from your garden. These types of barriers work by producing an unpleasant odor or taste that will keep moles away. But it is important to note that chemical barriers can also be harmful to other animals and the environment if not used properly.
Before using any type of chemical barrier, it is important to research and follow the instructions carefully. Here are some commonly used chemical barriers and how they work:
|How it Works
|Tip for Use
|Castor oil is a natural mole repellent that works by making the soil taste and smell unpleasant to moles.
|Apply castor oil directly to the soil and water it in. Reapply every few weeks or after heavy rain.
|Mothballs contain naphthalene, which is toxic to moles. The strong odor will also deter them from the area.
|Place mothballs in mole tunnels or near mole activity areas. Keep away from children and pets.
|Blood meal is a natural fertilizer made from dried animal blood. The high nitrogen content is attractive to moles, but the smell can be overwhelming and deter them from the area.
|Apply blood meal directly to the soil and water it in. Use gloves when handling and keep away from children and pets.
It is important to note that while chemical barriers can be effective, they should be used as a last resort and with caution. Always follow the instructions carefully and keep away from children and pets. Additionally, it is important to consider the potential harm to other animals and the environment before using any type of chemical solution.
Physical barriers are one of the most effective ways to keep moles out of your garden. They work by physically blocking the tunneling that moles use to move through your yard. There are a few different physical barrier options to choose from, including:
|Wire Mesh Fencing
|Easy to install
|Can be unsightly
May require maintenance
May not be effective against all types of moles
|Burying Hardware Cloth
|Effective at preventing moles from tunneling
Can be hidden underground
|May be difficult to install
Can be time-consuming
Can be expensive depending on the size of your yard
|Easy to install
Effective in small areas
|May not be effective for all types of moles
May need to be replaced frequently
Not practical for larger areas
When choosing a physical barrier, it’s important to consider the size of your yard, the type of soil you have, and the type of mole activity you are dealing with. Wire mesh fencing is a popular choice because it is affordable and easy to install, but it may not be effective against all types of moles. Burying hardware cloth is more effective but can be time-consuming and expensive depending on the size of your yard. Barrier tape is a good option for small areas, but may need to be replaced frequently and is not practical for larger areas.
Tip: No matter which physical barrier option you choose, it’s important to make sure the barrier extends deep enough into the ground to prevent moles from tunneling underneath it.
How to Create a Physical Mole Barrier
Protecting your garden from moles can be a daunting task, but creating a physical mole barrier can be an effective solution to keep these troublesome critters away. By digging a trench and installing the right materials, you can create a barrier that prevents moles from burrowing into your garden. In this section, we will guide you through the steps needed to create a physical mole barrier and maintain its efficacy over time. Read on to learn more.
Step 1: Dig a Trench
To create a physical mole barrier for your garden, the first step is to dig a trench. This trench should be about 8 inches wide and 24 inches deep so that it can accommodate the barrier material and fence.
Here are some detailed steps to follow while digging the trench:
|Mark the perimeter of the area where you want to put the barrier using stakes and string. This will give you a clear guide on where to dig the trench.
|Using a garden shovel or a trenching tool, dig the trench along the marked perimeter. Ensure that you create a uniform depth and width throughout the trench.
|As you dig, pile the soil neatly on one side or in a wheelbarrow for easy filling in later.
|Remove any weeds or roots that may get in the way of the barrier installation.
Take your time while digging the trench to ensure you get it right. Ensure that the walls and bottom of the trench are smooth without any protrusions, which would interfere with the installation of the barrier material.
Once you have completed digging the trench, you will be ready to move on to the next step in creating your physical mole barrier – installing the barrier material.
Step 2: Install Barrier Material
To install the barrier material for your mole barrier, you will need the following materials:
- Barrier Fabric: Choose a barrier fabric that is at least 18 inches wide so that it extends well into the sides of the trench.
- Staples: Use heavy-duty staples to secure the barrier fabric to the trench walls.
- Gloves: Wear gloves to protect your hands from any sharp objects or debris you may encounter during installation.
To install the barrier material, follow these steps:
- Unroll the barrier fabric and align it along the trench walls. Make sure the fabric extends at least 6 inches above the surface to prevent any moles from burrowing under the fabric.
- Using the heavy-duty staples, secure the barrier fabric to the trench walls. Make sure to pull the fabric tight and overlap any seams or joints to prevent any gaps where a mole could potentially tunnel through.
- Continue securing the barrier fabric around the perimeter of the trench until the entire area is covered.
Note: If you encounter any rocks or roots, make sure that the barrier fabric is placed over them and not underneath. Any gaps or openings in the barrier fabric will allow moles to tunnel through, so it’s important to ensure a tight, secure fit.
Step 3: Install Fence
To install a fence as part of your physical mole barrier, follow the below steps:
- Step 1: Choose a suitable fencing material that is sturdy and rust-resistant. Some popular options are galvanized steel or welded wire mesh.
- Step 2: Measure the length and height of the trench to determine the length and height of the fence you will need.
- Step 3: Cut the fence material to the appropriate length and height using wire cutters or tin snips.
- Step 4: Attach the fence material to the wooden stakes with staples or u-shaped nails. Make sure the fence is taut and secured properly to prevent any gaps.
- Step 5: Place the wooden stakes with attached fence into the trench, making sure the fence is facing inward towards the garden. Space the stakes evenly along the length of the trench.
- Step 6: Fill in the trench with the excavated soil, packing it tightly around the fence to ensure it is secure in place.
By following these steps, you will have successfully installed a fence as part of your physical mole barrier. The fence serves as a barrier that the moles cannot burrow through or climb over, protecting your garden from their destructive behavior. It’s important to monitor your barrier regularly for any signs of wear or damage and make necessary repairs to ensure its effectiveness in keeping moles at bay.
Maintaining Your Mole Barrier
Ensuring that your mole barrier remains effective over time requires ongoing maintenance and monitoring. Without proper care, your barrier may become damaged or ineffective, allowing moles to enter your garden once again. In this section, we will discuss the importance of maintaining your mole barrier and provide tips for monitoring and repairing it as needed. By staying diligent and proactive in your efforts, you can keep your garden protected against mole infestations for years to come.
Monitoring for Mole Activity
After creating a mole barrier around your garden, it is important to monitor for any mole activity in the area. This will help you detect and address any issues early, before they cause significant damage to your plants and lawn.
One way to monitor for mole activity is to visually inspect the ground for signs of mole hills or tunnels. Check the area around your garden regularly and look for raised, volcano-shaped piles of earth, as well as raised or sunken portions of the ground that may indicate the presence of tunnels.
Another method is to use mole traps to capture and remove moles from the area. Place traps along the perimeter of your garden and check them regularly for any captures. When using traps, it is important to follow the manufacturer’s instructions for proper placement and disposal.
You can also use baited tunnels to monitor for mole activity. Baited tunnels are tubes of PVC or other material that are placed along the mole barrier line and filled with bait. Check these tunnels regularly to see if any bait has been disturbed or taken, which may indicate mole activity in the area.
To effectively monitor for mole activity, use a journal or logbook to record any signs of mole hills or tunnels, captures, or bait consumption. This will help you keep track of any patterns or changes over time and make it easier to detect any issues before they become major problems.
Regular and consistent monitoring is key to maintaining the effectiveness of your mole barrier and protecting your garden from mole damage. By following these monitoring techniques, you can ensure that your barrier remains intact and your garden stays protected.
|Regularly checking the area around your garden for signs of mole hills or tunnels
