Natural Repellents

Natural Repellents
Natural repellents can be a great alternative to chemical repellents when it comes to controlling mole infestations. These repellents are made from natural ingredients and are usually safer for the environment and pets. However, there are many natural repellents available and it can be difficult to determine which ones are actually effective. In this section, we will explore some of the most widely used natural repellents for moles and examine their effectiveness in deterring these pests.

1. Castor Oil

Castor oil is a popular natural repellent for moles. It is considered one of the most effective ways to deter moles from digging up your lawn. Castor oil is derived from castor beans and is safe for use around children and pets, making it an environmentally friendly option.

To use castor oil as a mole repellent, mix it with water and spray it over the affected area. The mixture will penetrate the soil and create an unpleasant environment for the moles, causing them to move elsewhere. One of the advantages of using castor oil is that it not only repels moles but also other pests such as voles and gophers.

Another way to use castor oil is by creating a castor oil barrier around your garden or lawn. To do this, dilute the castor oil with water and apply it to an area surrounding your garden or lawn. The smell will keep the moles away, as they do not like the scent of castor oil.

However, one drawback of using castor oil is that it may take longer to see results compared to chemical repellents. It may take several applications before the moles are completely deterred from your garden or lawn. Additionally, castor oil may not be effective in areas with heavy rainfall, as the rain may wash the oil away.

Castor oil is an effective natural repellent for moles that is safe for use around children and pets. It may take longer to see results compared to chemical repellents, but it is a great eco-friendly alternative.

2. Garlic

Garlic has been known as a natural repellent for many insects and animals, including moles. The strong odor of garlic is the main reason why moles tend to avoid areas where it is used.

How to use garlic as a mole repellent:

One way to use garlic as a mole repellent is by making a garlic spray. To do this, you will need to:

  1. Finely chop several garlic cloves and add them to boiling water.
  2. Let the mixture cool and strain out the garlic pieces.
  3. Pour the liquid into a spray bottle and apply it to areas where moles are present.
  4. Reapply after rain or every few days to maintain its effectiveness.

It’s important to note that the strong odor of garlic may also be unpleasant for humans, so it’s best to only use garlic spray in areas away from outdoor seating or living areas.

Pros of using garlic as a mole repellent:

  • Garlic is a natural and safe alternative to chemical repellents.
  • Garlic is easily accessible and can be found in most grocery stores and gardens.
  • Garlic can be used to repel other pests, such as mosquitoes and aphids.

Cons of using garlic as a mole repellent:

  • The odor of garlic may not be effective for all moles, and some may become accustomed to it over time.
  • Garlic spray needs to be reapplied frequently, especially after rain, to maintain its effectiveness.
  • The strong odor of garlic may be unpleasant for humans as well.

While garlic has been known to repel moles, it may not be the most effective natural option. Other natural remedies such as using plants that moles dislike or castor oil may be more effective. If natural remedies do not work, chemical repellents may be necessary for effective mole control.

3. Eucalyptus Oil

Eucalyptus oil is another natural repellent that has shown some effectiveness in deterring moles. It works by emitting a strong odor that the moles find unpleasant, causing them to stay away from the treated area. Eucalyptus oil is also known to have antiseptic and anti-inflammatory properties, making it a safe and natural choice for pest control.

To use eucalyptus oil as a mole repellent, mix a few drops of the oil with water and apply it to the soil in the areas where moles are present. One of the benefits of using eucalyptus oil is that it can also repel other pests such as mosquitoes and flies.

However, it’s important to note that eucalyptus oil may not be as effective as other natural or chemical repellents, and it may require more frequent reapplication to maintain its effectiveness. Additionally, the strong odor may not be desirable for some people.

Pros Cons
Eucalyptus oil is a natural and safe option for pest control. May not be as effective as other natural or chemical repellents.
Has antiseptic and anti-inflammatory properties. Requires more frequent reapplication to maintain effectiveness.
Repels other pests such as mosquitoes and flies. The strong odor may not be pleasant for some people.

4. Plants

Plants are another natural way to prevent moles from invading your yard. Certain plants have a strong odor that moles find repulsive. By planting these around the perimeter of your yard or near areas where moles have been active, you can deter them from coming any closer.

Some plants that are known to repel moles include:

  • Castor bean plants
  • Daffodils
  • Alliums (such as garlic and onions)
  • Fritillaries
  • Mole plant

Castor bean plants contain ricin, which is toxic if ingested, so precautions should be taken if you have children or pets. Daffodils and fritillaries are toxic if ingested by pets, but they are safe for humans. Alliums, such as garlic and onions, have a strong smell that moles dislike and are safe for both humans and pets. Mole plant, also known as euphorbia lathyris, has a strong odor and produces a milky sap that is toxic to moles.

Planting any of these around your yard may help deter moles from entering. However, it’s important to note that using plants as a repellent may not be as effective as other methods, as moles may simply dig deeper to avoid the odor. Additionally, planting these plants in your yard may not be enough to completely rid your yard of moles.

Proper precautions should also be taken when planting these plants in order to avoid any potential harm to you or your pets.

Chemical Repellents

Chemical Repellents
Chemical repellents can be an effective way of deterring moles from your property. These products contain powerful chemicals that are designed to be harmful to moles, making them an attractive option for those who want a speedy solution to their mole problem.

Pros and Cons of Natural Repellents

Pros And Cons Of Natural Repellents
When it comes to repelling moles from your garden or yard, there are numerous options available, including various natural and chemical repellents. While both types of repellents have their benefits and drawbacks, understanding the pros and cons of each can help you make an informed decision on which one to use. In this section, we will discuss the advantages and disadvantages of natural mole repellents, so you can determine which method of mole control is the right one for you.


When it comes to chemical repellents, there are certainly some pros to consider. Here are some advantages of using chemical mole repellents:

  • Efficiency: Chemical repellents are known to be highly effective at getting rid of moles. They are specifically designed to eliminate or deter these pests, often through means that are not found in natural repellents.
  • Convenience: Using chemical repellents is often very convenient. Many can be purchased as sprays, meaning that you can simply apply them whenever you need to without extensive preparation or work on your part.
  • Long-lasting: Unlike natural repellents, which may need to be reapplied frequently in order to be effective, many chemical mole repellents have a long-lasting formula that can continue to work for weeks or even months at a time.
  • Strong formula: Chemicals are often more potent than natural ingredients, which can make them more effective and faster acting than their natural counterparts. They also might work better in soil than natural repellents.

It’s important to keep in mind that while there are some benefits to using chemical repellents, there are also some downsides to consider.


While natural repellents have their benefits, there are also some drawbacks to using them. Here are some of the potential cons to keep in mind:

  • Inconsistent Results: Natural repellents may not work as effectively or consistently as chemical repellents. The effectiveness of the repellent can depend on various factors, such as the concentration used, the type of soil or vegetation in the area, and the weather conditions. This unpredictability can be frustrating if you’re hoping for a quick and guaranteed solution.
  • Shorter Lifespan: Natural repellents can also have a shorter lifespan compared to chemical repellents. Because these products are made from natural ingredients, they can break down more quickly due to exposure to sunlight, rain, and other elements. This means you may need to reapply the repellent more frequently to keep moles at bay.
  • Odor: Some natural repellents, such as garlic and castor oil, can have a strong odor that may not be pleasant for everyone. Additionally, the odor may not dissipate quickly, which can be a problem if you’re using the repellent in an area where you’d like to spend time outside.
  • Attract Other Pests: Finally, it’s worth noting that some natural repellents may not only repel moles but also attract other pests. For example, some plants that are known to repel moles, like marigolds, may also attract aphids, a type of insect that feeds on plants. This could ultimately create a new problem that you’ll need to address.

Ultimately, you’ll need to weigh the pros and cons of natural repellents to decide if they’re the right solution for your mole problem. While they may be a gentler and more eco-friendly option, they may also require more effort and may not provide the same level of reliability as chemical repellents.

Pros and Cons of Chemical Repellents

Pros And Cons Of Chemical Repellents

However, it’s important to weigh the pros and cons of using chemical repellents before making a decision. On one hand, chemical repellents can be fast-acting and provide long-lasting results. On the other hand, they can also be harmful to the environment and potentially risky to use around children and pets.

  • Long-lasting: Many chemical repellents can last for several months before needing to be reapplied, which means less maintenance for the homeowner.
  • Versatile: There are several different types of chemical repellents available, each with their own unique active ingredients and modes of action, which means you can choose the one that works best for your specific mole problem.
  • Large Coverage Area: Chemical repellents can cover a larger area, which is useful if you have a large property or just want to ensure that you are taking care of the mole problem in one go.

Chemical repellents can be a great option for those who need to quickly and effectively get rid of moles in their yard. However, it’s important to weigh the pros and cons to decide if it is the right choice for you, as using chemical repellents does have some potential drawbacks as well.


When it comes to natural repellents, there are some cons to consider. These include:

Expense: Natural repellents can be more expensive than chemical ones because they require more frequent applications.
Effectiveness: Natural repellents may not be as effective as chemical ones, especially in severe mole infestations.
Time-consuming: Natural repellents may need to be reapplied frequently and require more preparation time, such as brewing garlic spray or planting specific plants.
Odor: Some natural repellents can give off strong odors that may not be appealing to some people.

It’s important to weigh these cons against the potential benefits of using natural repellents. While they may require more effort, they also offer a safer and more eco-friendly option. Ultimately, the choice between natural and chemical repellents will depend on your individual needs and preferences.

How to Choose the Best Repellent for Your Needs

When it comes to choosing the best repellent for your needs, there are several factors to consider. Firstly, you need to think about the severity of the mole problem you are facing. If you only have a few moles in your yard, then a natural repellent may be sufficient. However, if you are dealing with a large infestation, a chemical repellent may be necessary.

You should consider the safety of the repellent. If you have children or pets who roam around your yard, you will want to choose a repellent that is safe for them. Natural repellents are generally considered to be safer than chemical ones, but it’s still important to follow the instructions carefully and keep them out of reach of children and pets.

Another factor to consider is the effectiveness of the repellent. While natural repellents can be effective, they may not work as quickly or as thoroughly as chemical repellents. If you need results fast, a chemical repellent may be your best bet.

Cost is also a consideration. Natural repellents are often less expensive than chemical ones, but you may need to apply them more frequently to achieve the same results. On the other hand, chemical repellents can be more expensive upfront, but they may last longer and require less frequent application.

Ultimately, the best repellent for your needs will depend on your specific situation. Natural repellents may be a good choice for those who are dealing with a mild mole problem and are concerned about safety and cost. Chemical repellents may be a better choice for those who have a more severe mole problem and need quick and effective results.

It’s important to carefully read the instructions on any repellent you choose and follow them closely to ensure the best results. Additionally, it’s always a good idea to consult with a professional pest control expert to get their recommendations on the best repellent for your specific situation.


After comparing natural and chemical repellents for moles, it is evident that both have their pros and cons. Natural repellents are environmentally friendly and pose no harm to pets or humans. Castor oil, garlic, eucalyptus oil, and plants have been found to be effective in repelling moles. However, their effectiveness may vary depending on factors such as location, soil texture, and weather conditions. Additionally, natural repellents require frequent reapplication to ensure continuous protection.

Chemical repellents, on the other hand, offer quick and long-lasting protection against moles. Mole poison, repellent spray, and smoke bombs have been found to be effective in getting rid of moles. However, chemical repellents may contain harmful chemicals that pose a danger to pets, humans, and the environment. Some of them may also kill beneficial animals like earthworms, which help to improve soil quality.

When choosing the best repellent for your needs, it is essential to consider factors such as safety, effectiveness, and environmental impact. If you have pets or children playing in the yard, it is wise to choose a natural repellent that poses no danger to them. If you want a quick and long-lasting solution, chemical repellents may be the best option for you. However, before using any chemical repellents, it is crucial to read the label carefully and follow the instructions to avoid any harm.

In conclusion, both natural and chemical repellents have their advantages and disadvantages. It is up to you to decide which option fits your needs best. As a reminder, it is always recommended to take precautions and safety measures when using any repellents.
