The Benefits and Drawbacks of Moles Migration

As homeowners, we always strive to keep our lawns and gardens looking their best. However, when moles migrate into our properties, they can wreak havoc on our carefully crafted outdoor spaces, causing damage and frustration. But before we rush to get rid of the moles, we should also consider the benefits they offer. In this article, we will explore both the advantages and disadvantages of moles migration, and discuss some effective ways to control them.

The Benefits of Moles Migration

The Benefits Of Moles Migration
As perplexing as it may sound, the migration of moles comes with its benefits. These tiny creatures are often misunderstood as pests, but they actually play a vital role in maintaining healthy soil. From increasing soil aeration to providing natural pest control, moles have positive impacts on the environment. Understanding these benefits is necessary to strike a balance between moles’ presence and maintaining your lawn or garden. For more information on mole migration patterns, take a look at our article /understanding-moles-migration-patterns/.

Increased Soil Aeration

When moles migrate into an area, one of the benefits is an increase in soil aeration. This is because moles burrow through soil, creating small tunnels and air pockets. These air pockets allow for better circulation of air, water, and nutrients through the soil. As a result, plant roots are better able to absorb these vital resources, leading to healthier and more robust growth.

Moles also help to break up compacted soil, which can be a challenge for gardeners and landscapers. Compacted soil can make it difficult for water to penetrate, which can make it hard for plants to grow properly. By burrowing through the soil, moles create channels that allow water and nutrients to penetrate more deeply, leading to healthier plants.

Moles’ burrowing activities can help to improve soil drainage, which can be beneficial in areas with heavy rainfall. By creating small channels for water to flow through, moles can help to prevent water from pooling on the surface and causing damage to plants and structures.

While there are benefits to increased soil aeration from moles, it’s important to note that excessive tunneling can also have drawbacks. For example, if moles burrow too close to the surface, they can create unsightly mole hills and damage to lawns and gardens. Additionally, their tunneling can create pathways for other pests, such as gophers and voles, to enter an area and cause damage.

Natural Pest Control

Natural pest control is one of the benefits of moles migration. Moles feed on grubs, insects, and worms that can cause damage to crops and gardens. By controlling these pests, moles help maintain a balanced ecosystem. They do not typically prey on beneficial insects, such as ladybugs, which are essential for controlling harmful pests.

Here are some of the pests that moles help control:

  • Japanese beetles
  • Grubs
  • Slugs
  • Moles also feed on earthworms, which are useful for aerating the soil. However, their impact on earthworm population may be less positive in some circumstances.

While moles may cause damage to lawns and gardens, they also help keep insect populations in check. The key is to find a balance between the benefits and drawbacks of moles migration.

If you have a pest problem, it is important to identify the pests before taking any action. This is because moles may not be the only pest that is causing damage. For example, if your plants are being damaged by slugs, you may need to take additional measures to control slug population.

Despite their benefits, moles can become a nuisance if left uncontrolled. In the next section, we’ll discuss some of the ways to control moles migration, including mechanical traps, repellents, and natural methods.

Improved Soil Health

Improved Soil Health: Moles are often beneficial for soil health as their digging and tunneling activities help to aerate the soil. By loosening the soil, they promote root growth, which in turn helps to support plant growth. Additionally, their burrowing creates channels for water and other nutrients to penetrate deeper into the soil, which can be especially important in compacted soils. Moles also help to mix soil layers, bringing nutrients from deeper layers up to the surface, and excreting waste materials that can further enhance soil quality.

According to a study conducted by the University of Massachusetts, the soil in areas with mole activity had improved texture, better drainage, higher levels of organic matter, and improved nutrient availability compared to soil in areas without mole activity. The study found that the presence of moles led to a decrease in soil compaction, which can inhibit plant growth.

However, it is important to note that the benefits of mole activity on soil health can vary depending on factors such as soil type, climate, and the severity of mole infestations.

Damage to Lawn and Garden

Moles migration may bring many benefits to the soil and the ecosystem, but they can also cause some harm to the lawn and garden. The presence of moles can lead to damage above and below the ground, which can be costly and frustrating for homeowners.

Above-Ground Damage: Moles create tunnels and molehills as they burrow underground, which can be unsightly and make mowing difficult. The tunnels made by moles can scar the ground and create uneven areas in the lawn. Also, as moles push up little mounds of dirt to the surface, it can make the lawn look bumpy and rough. Any new growth is vulnerable to damage, as the roots of the plants can be broken as the moles tunnel through the ground. This can cause the plants to lose nutrients and wilt.

Below-Ground Damage: While moles primarily eat insects and grubs, their burrowing can also damage plant roots, bulbs, and tubers. With enough time, a mole infestation can cause significant damage to the garden or the foundation of the home. Also, when the soil is soft and wet, the tunnels created by moles can lead to soil erosion and cause structural damage to the property.

To prevent any potential mole damage, homeowners should take necessary precautions, such as using mole repellents, installing underground barriers, or reaching out to pest control professionals. It’s essential to address the problem promptly as large-scale infestations can be difficult and costly to manage.

Creation of Visible Mole Hills

One of the drawbacks of moles migration is the creation of visible mole hills. These mounds are formed as moles dig tunnels underground, pushing excess dirt to the surface. Mole hills can be unsightly and make lawn maintenance difficult. They can also be dangerous if not seen and tripped over.

Mole hills can vary in size and shape, but generally range from 4 to 8 inches in diameter and 2 to 4 inches in height. They are typically conical or dome-shaped, with a depression or hole at the top where the mole entered or exited the tunnel.

While mole hills can be a nuisance for homeowners, they are also a sign that moles are present and actively tunneling. This can be helpful information for those who want to control mole populations on their property.

Secondary Pest Infestations

One of the drawbacks of moles migration is the possibility of secondary pest infestations in the lawn or garden. Moles are known to feed on insects, worms, and grubs, which are considered pests to lawns and gardens. However, when they migrate, they also leave behind a trail of disturbed soil that can attract other pests.

Ants, in particular, are known to take advantage of the tunnels that moles create. The tunnels provide a pathway for ants to access the surface of the soil and the roots of plants. Once they discover the tunnels, they may create colonies within them, which can result in an ant infestation. Additionally, the soil that moles migrate through can become churned up, providing an ideal breeding ground for other pests, like flies and mosquitoes.

To prevent secondary pest infestations, it’s important to address any mole activity as soon as possible. This can involve using traps or repellents to remove the moles from the area. In some cases, additional measures may be needed, like the application of insecticides or the use of natural pest control methods. If secondary pest infestations do occur, they will also need to be addressed in order to prevent damage to the lawn or garden.

While moles migration can provide numerous benefits to the soil and ecosystem, there are also drawbacks that must be considered, such as the possibility of secondary pest infestations. By being proactive in addressing any mole activity or signs of secondary pest infestations, property owners can help to prevent damage and maintain a healthy lawn or garden.

How to Control Moles

Controlling moles can be a challenging task for homeowners who wish to maintain the beauty of their lawns and gardens. However, there are various techniques available to prevent and eliminate these pesky creatures from causing further damage. From mechanical traps to natural control methods, the options are plentiful, but choosing the right method can be perplexing for some. In this section, we will take a closer look at some effective ways of controlling moles and keeping them at bay. Don’t miss out on tracking moles migration using technology to enhance your control methods.

Mechanical Traps

Mechanical traps are an effective means of controlling mole populations. There are various types of mechanical traps available on the market, each with its own unique design and function. These traps function through either impaling or asphyxiating the mole.

One popular type of trap is the scissor-jaw trap. This type of trap features two interlocking metal jaws that are triggered to close when a mole passes through them. Once triggered, the mole is caught and killed instantaneously. Another popular trap is the harpoon trap, which impales the mole when triggered. Both types of traps are designed to be placed in active mole tunnels for optimal effectiveness.

When using mechanical traps, it is important to place them properly to ensure that they are effective. It is recommended to place the traps in active tunnels, which can be identified by the presence of fresh mole activity such as raised ridges or fresh soil that has been pushed up. It is also important to handle the traps with caution and to follow the manufacturer’s instructions carefully to avoid injury.

While mechanical traps can be an effective solution for controlling moles, they do require regular monitoring to ensure that they are still active and properly placed. It is also important to note that mechanical traps do not prevent moles from entering a property, so it may be necessary to use other methods in conjunction with traps for optimal results.


One of the methods for controlling moles is to use repellents. There are several types of repellents that can be used, each with varying degrees of effectiveness.

Repellent Type Effectiveness Pros Cons
Castor Oil Low to Medium Safe for pets and children May take several applications to be effective
Ultrasonic Low Safe for pets and children May not be effective as a sole method of control
Plants Low Natural and non-toxic May not be effective in heavily infested areas

Castor oil based repellents have been shown to be moderately effective in controlling moles. They work by coating the moles’ food sources, making them unappetizing and pushing the moles to move to a new area. However, multiple applications may be necessary for it to be effective.

Ultrasonic repellents emit a high-frequency sound that is supposed to be unpleasant for moles and other pests. However, their effectiveness is questionable as they may not work in all soil types and may not be sufficient as a sole method of control.

Plants like daffodils, alliums, and marigolds are known to repel moles due to their strong odor. While this method is natural and non-toxic, it may not be effective in heavily infested areas.

Natural Control Methods

When it comes to controlling moles, natural control methods can be effective and environmentally friendly alternatives to mechanical traps and repellents. Some natural control methods to consider include:

  • Planting natural deterrents: Certain plants, such as marigolds, castor bean plants, and daffodils, are known to repel moles due to their strong scents or toxic properties. By planting these natural deterrents in your yard or garden, you can help discourage moles from making a home there.
  • Encouraging natural predators: Natural predators of moles, including snakes, owls, and hawks, can help keep mole populations under control. By creating a welcoming habitat for these predators in your yard, such as by adding a birdhouse or bat box, you can encourage them to frequent your property and hunt moles.
  • Improving soil drainage: One reason moles may seek out your yard or garden is because of poorly-draining soil. By improving soil drainage through methods such as adding compost, aerating the soil, or creating raised beds, you can make your yard less hospitable to moles and other burrowing pests.
  • Removing their food source: Moles feed on insects and other small creatures, so reducing the populations of these pests in your yard can help make it less appealing to moles. Consider using natural pest control methods, such as introducing beneficial nematodes or planting insect-repelling herbs like basil or mint, to discourage pests from living in your yard.

By utilizing natural control methods, you can help keep mole populations in check while also maintaining a healthy and eco-friendly yard or garden. However, it’s important to note that natural control methods may take longer to show results and may not be as effective as other control options. Experiment with different methods to find what works best for your situation.


In conclusion, while the migration of moles can bring some benefits to your lawn and garden such as increased soil aeration, natural pest control, and improved soil health, there are also drawbacks to consider such as damage to the lawn and garden, the creation of visible mole hills, and the potential for secondary pest infestations.

It’s important to weigh the pros and cons of mole migration and determine if their presence is worth the potential damage. If you do decide to take action to control moles, there are several options available. Mechanical traps can be effective, but they require skill and patience. Repellents may work for a short time, but they need to be applied frequently. Natural control methods such as companion planting and encouraging predators like birds and snakes can also be effective.

Ultimately, the best approach will depend on your individual situation and preferences. If the benefits of moles outweigh the drawbacks, then it may be best to simply tolerate their presence. However, if the damage is too great, taking action to control their population may be necessary. Whatever you decide, it’s important to consider the impact on both the moles and your lawn and garden ecosystem.
