Know Why Moles Invade Your Yard

Moles are small burrowing mammals that can cause significant damage to your yard and garden in winter. It’s important to understand why moles invade your yard so that you can take the necessary steps to prevent them from doing so. Here are some reasons why moles may be attracted to your yard:

  • Food: One of the most common reasons moles invade yards is in search of food. They typically feed on insects and grubs that live in the soil, and if your yard has a large population of these creatures, moles will be naturally drawn to it.
  • Shelter: Moles need shelter from harsh winter weather, and your yard may provide the perfect space for them to burrow and stay warm. They prefer areas with loose or moist soil, which makes it easier for them to dig tunnels and construct their burrows.
  • Mating and Colonization: During winter, moles search for potential mates and areas to colonize, and your yard might be a suitable habitat for them to do so. If they are able to find a safe and secure place to settle, they may remain in your yard even after winter passes.

Paying attention to the reasons why moles might be invading your yard can help you take the necessary measures to prevent their presence. By addressing these factors, you can reduce the chances of attracting moles and keep your lawn and garden healthy and mole-free.

Learn How Moles Spend Winter

During winter, moles tend to burrow deeper underground in search of food and warmth. They slow down their metabolic rate and reduce their activity level by up to 90%, conserving energy in order to survive the cold winter months.

Here is a table that highlights some of the ways moles spend their winter:

Activity Level Reduced by up to 90%
Movement Slower, but still active underground
Burrowing Deeper underground to access food and warmth
Diet Primarily earthworms and insect larvae
Reproduction Generally dormant during winter
Behavior May move closer to buildings or structures for warmth

It is important to understand how moles spend their winter in order to effectively prevent and control infestations in your lawn or garden. By providing alternative sources of food and warmth, alongside implementing preventative measures, it is possible to discourage moles from invading your outdoor space during the colder months.

Identify the Signs of Mole Infestation

Identify The Signs Of Mole Infestation
Have you noticed unusual signs of damage in your lawn or garden lately? Are you wondering if moles may have invaded your yard? It’s important to be able to identify the signs of mole infestation early on, so you can take action to prevent further damage. By inspecting your yard regularly and knowing what to look for, you can catch mole infestations before they become a bigger problem. Keep an eye out for mounds, burrows, and surface tunnels–these are all common signs that moles may be present. Let’s take a closer look at how to identify mole infestations in your yard.

Inspect Your Yard Regularly

Regular inspection of your yard is crucial in identifying the signs of mole infestation. Here are some steps to follow when inspecting your yard:

1. Walk around your yard: Take a walk around your yard and look for signs of mole activity. Be sure to inspect all areas of your lawn, including areas that are not highly trafficked.

2. Look for raised areas: Moles create raised areas called molehills or mole mounds in your lawn. These mounds are created as moles burrow beneath the ground and push up dirt as they move.

3. Check for surface tunnels: Moles also create surface tunnels that run along the top of your lawn. These tunnels can be identified by looking for raised strips of soil with no visible entrance or exit.

4. Inspect plant roots: Moles feed on earthworms and grubs in the soil, so their presence can also be identified by inspecting the roots of your plants. Look for root systems that have been damaged or appear to have tunnels underneath them.

5. Look for irregularities: Finally, watch for any irregularities in your lawn, such as sinking ground or unusual amounts of soil on the surface. These can be signs of extensive mole activity.

By regularly inspecting your yard and looking out for the above signs, you can quickly identify a mole infestation and take steps to eliminate the problem before it gets out of control.

Identify Mole Mounds, Burrows and Surface Tunnels

One of the key steps in preventing mole infestations in winter is to identify the signs of their presence in your yard. Here are some of the things that you should look out for:

Signs of Mole Infestation How to Identify
Mole Mounds These are raised, volcano-shaped piles of soil that are often found in the middle of your lawn or garden. They are created when moles dig tunnels and push the soil up to the surface. You may notice that the soil in the mounds is loose and contains no vegetation.
Burrows Moles create a network of underground tunnels as they search for food. You may notice small openings in the ground with no obvious mound of soil. These are the entrances to the tunnels.
Surface Tunnels These are shallow tunnels just below the surface of your lawn or garden. They can be identified by raised ridges of soil that run across your lawn in a squiggly pattern.

It’s important to regularly inspect your yard for these signs of mole activity, as catching infestations early can save you a lot of time and effort in the long run.

Eliminate Moles with Simple DIY Techniques

Eliminate Moles With Simple Diy Techniques
Are moles ruining your beautiful yard and garden? Trying to get rid of them can be a daunting task. However, there are ways to eliminate moles without having to spend a lot of money on professional services. By using simple DIY techniques, you can take matters into your own hands and get rid of these burrowing rodents once and for all. Let’s take a look at some effective methods that you can try out today.

Use Castor Oil-Based Mole Repellents

When it comes to getting rid of moles in your yard, using castor oil-based mole repellents can prove to be an effective and eco-friendly solution. Castor oil is derived from the seeds of the castor bean plant and contains a compound called ricinoleic acid, which has natural repellent properties that can deter moles from invading your yard. Here are some ways to use castor oil-based mole repellents:

Method Description
1. Castor oil spray Mix 6 ounces of castor oil with 2 tablespoons of dish soap in a gallon of water. Spray the mixture on your lawn and in areas with mole activity. Repeat the process every 3-4 weeks until moles are gone.
2. Castor oil granules Spread castor oil granules on your lawn and around mole activity. The granules will dissolve when it rains, spreading the castor oil and creating an unpleasant environment for moles. Repeat the process every 2-3 months.
3. Castor oil repellent plants Plant castor oil plants, also known as Ricinus communis, around the perimeter of your yard. The plants’ strong scent can act as a natural mole repellent.

It’s important to note that while castor oil-based repellents are generally safe for pets and wildlife, it’s recommended to keep them away from the treated areas until the product has dried. Additionally, it’s important to follow the instructions carefully and to be patient. Castor oil-based mole repellents may take some time to fully eliminate mole activity in your yard, but with persistence and consistency, it can be an effective solution.

Set up Live Traps

If you prefer a humane approach to getting rid of moles, then setting up live traps might be a viable option for you. Follow these steps to correctly set up live traps:

  • Step 1: Choose an appropriate trap – There are various types of live traps available. Choose one that is specifically designed for mole control.
  • Step 2: Identify active mole tunnels – Use a probe or shovel to locate active mole tunnels. These are the tunnels that are currently in use by the moles.
  • Step 3: Place the trap – Place the trap in the active tunnel. Ensure that the trap is placed in a straight line along the tunnel.
  • Step 4: Cover the trap – Cover the trap and the tunnel with soil, leaves or grass. You want to make sure that there are no air pockets or gaps that can reveal the trap to the moles.
  • Step 5: Check the trap frequently – Check the trap frequently to see if it has caught any moles. If so, release the moles at least five miles away from your property.
  • Step 6: Repeat the process – Repeat the process in other active mole tunnels until the infestation has been successfully eliminated.

Remember that while live traps may be a humane option, they may not always be effective in eliminating the infestation. In some cases, it may be necessary to combine live traps with other DIY techniques or seek professional help.

Prevent Moles from Coming Back in Winter

As winter brings the cold, it may seem like moles disappear entirely, but unfortunately, that is not the case. In fact, moles can be more damaging in the winter months as they search for warmth and food. To prevent these pesky critters from coming back to invade your yard, there are several techniques and methods you can use. In this section, we will explore some ways to keep your yard mole-free during the winter months.

Water Your Lawn and Garden Adequately

Keeping your lawn and garden adequately hydrated is an essential step in preventing moles in winter. Moles prefer to burrow and feed in areas with moist soil. If you maintain proper hydration levels, you are less likely to experience a mole infestation. Here are some tips for ensuring that your lawn and garden stay adequately hydrated:

1. Water Deeply When you water your lawn and garden, make sure to water deeply. This means giving your lawn and garden a good soak, so the water penetrates deep into the soil. This will encourage grass roots to grow deep, making it harder for moles to tunnel through.
2. Water in the Morning Watering in the morning is the best time to water your lawn and garden. This is because the temperature is cooler, and winds are usually calmer, allowing the water to penetrate the soil more efficiently. Additionally, watering in the morning will prevent the soil from staying too wet overnight, which can lead to fungal diseases.
3. Use a Sprinkler System Using a sprinkler system is an easy way to ensure that your lawn and garden are getting enough water. Most systems are programmable, allowing you to water your lawn and garden at specific times, so you don’t have to worry about forgetting to water. This will also ensure that your lawn and garden are getting enough water even if you are away from home.
4. Consider Mulching Mulching helps to retain moisture in the soil, which can be particularly helpful during dry spells. This is because mulch acts as a barrier, preventing evaporation and keeping the soil moist for longer. Additionally, mulch helps to regulate soil temperatures, which can be particularly helpful during the winter months.

By following these tips, you can ensure that your lawn and garden stay adequately hydrated, reducing the likelihood of a mole infestation.

Employ Companion Planting Techniques

Companion planting is an age-old technique that has been successfully used to promote plant growth, enhance soil fertility, and deter pests. By planting certain plants next to each other, you can create a natural pest control system that can help prevent moles from taking over your garden in the winter.

Plant Marigolds: Marigolds are known to repel moles as they emit a strong odor that the rodents do not like. You can plant them around the perimeter of your garden, or interplant them with your other flowers or vegetables.

Plant Alliums: Alliums, including onions, garlic, and chives, are also effective in keeping moles away. These plants have a strong scent that moles don’t like, so you can plant them near the plants that are susceptible to mole damage.

Plant Daffodils: Daffodils are another plant that moles don’t like. They contain a toxic chemical that moles avoid, making them an effective deterrent. Plant them in the fall for the best results.

Plant Castor Beans: Castor beans contain a substance called ricin, which is poisonous to moles. You can plant them around the perimeter of your garden, but be careful as the seeds of the castor bean plant are highly toxic to humans and animals.

Plant Fritillaries: Fritillaries are a group of plants that are known to repel moles. They contain a substance called verticillium that is toxic to moles and other rodents. Plant them in the fall together with daffodils for best results.

By using companion planting techniques, you can create a natural and effective way to deter moles from coming back to your garden in the winter. When you plant the right combination of plants, you create a natural barrier that is inhospitable to these rodents.

Install Barriers to Keep Moles Out

One effective way to prevent moles from invading your yard in the winter is to install barriers that will keep them out. There are a variety of materials that you can use to create these barriers. Here are some options:

Barrier Material Pros Cons
Hardware cloth – Durable– Allows for air and water flow – Can be expensive– Time consuming to install
Bird netting – Inexpensive– Easy to install– Flexible – May not be as durable– Can entangle wildlife
Chicken wire – Inexpensive– Easily shaped to fit the area – May not be as durable– Can rust over time

No matter what type of barrier material you choose, it is important to make sure that it is tall enough, at least 2 feet, to prevent moles from burrowing underneath. Additionally, bury the barrier into the ground at least 6 inches to prevent the moles from digging under it. By installing barriers, you can effectively keep moles out of your yard and prevent them from damaging your lawn and garden in the winter.


In conclusion, mole infestations can be a frustrating problem for homeowners, especially during the winter months. However, with a little understanding of mole biology and some proven prevention techniques, you can successfully manage and control their invasion. Inspecting your yard regularly is key to identifying mole activity early on, allowing you to take action before significant damage occurs. Techniques such as using castor oil-based mole repellents and setting up live traps can be effective in eliminating moles in your yard.

To prevent moles from coming back, ensure you water your lawn and garden adequately and employ companion planting techniques to keep soil disturbance to a minimum. Installing barriers such as fences or mesh can also help keep moles out of your yard. Don’t forget, it’s important to act quickly as soon as you notice signs of mole activity to prevent the problem from getting out of hand.

Overall, preventing moles in winter may require a bit of effort, but with persistence, you can keep your lawn and garden healthy and mole-free.
