Why Marigolds Are Effective Against Moles
If you are tired of moles creating tunnels and mounds in your garden, you might be interested in using natural mole deterrents to fix the problem. Marigolds is one of the popular organic solutions that have proven to be effective in keeping these pests at bay. But have you ever wondered why marigolds are a potent mole repellent?

What Makes Marigolds a Powerful Mole Repellent

Marigolds are a powerful mole repellent and are an excellent tool for keeping moles away from gardens and lawns. There are several factors that make them a great natural deterrent for moles.

Strong Odor: One of the reasons that marigolds are effective against moles is their strong odor, which is unpleasant to moles. Moles rely heavily on their sense of smell to locate food sources, and the pungent scent of marigolds disrupts their ability to find prey.

Indigestible: Another reason marigolds are effective is that they are toxic or at least indigestible to moles. Moles are insectivores and can be expected to munch on most plants, but marigolds are frequently left untouched.

Root Exudates: Certain compounds released by marigold roots, such as alpha-terthienyl and methylisothiocyanate, are also known to be toxic to moles, affecting the quality of soil they rely upon to live.

The above reasons makes marigolds a powerful mole repellent. Additionally, when used in combination with other natural deterrents, marigolds will make sure that pesky moles will stay away from the lawn or garden.

How Marigolds Work in Deterring Moles

Marigolds are a powerful natural **mole repellent** due to the strong scent they emit, which moles find unpleasant. These flowers produce a distinctive odor that overwhelms and confuses the mole’s sense of smell, making it difficult for them to locate their prey or move around their environment. Additionally, marigolds’ roots secrete a substance that is toxic to many pests, including moles.

Marigolds trigger the mole’s instinct to avoid danger, and this makes these flowers an effective tool in deterring moles from damaging gardens and lawns. When planting marigolds, it is essential to do so strategically so that they work to their fullest potential.

To experience their full effectiveness, marigolds also need to be healthy and free of wilting or drying out. When they are well maintained, it is less likely that moles will get near marigolds.

While marigolds are known for their effectiveness against moles, it is important to note that they should not be the only method used to deter moles. Combining several different repellents can significantly increase their efficacy, especially when used in conjunction with the preventative measures.

Choose the Right Type of Marigolds

Choosing the Right Type of Marigolds

Not all marigolds are equally effective in repelling moles. When choosing marigolds to deter moles, it’s essential to select the appropriate species. There are primarily two marigold species that gardeners use for mole control, the Mexican Marigold (Tagetes lucida) and the French Marigold (Tagetes patula). Both types are excellent in repelling moles, but the Mexican marigold is slightly more effective.

The Mexican marigold, also called sweet mace or winter tarragon, is a strong-scented herb that can repel a wide range of pests, including moles. It has small yellow flowers and is widely cultivated in Mexico as a spice and medicinal herb.

French marigold has a pungent odor that repels not only moles but other pests as well. This annual plant features bright and large orange or yellow flowers that bloom throughout the summer.

It’s necessary to look for marigold varieties that are known to be effective in repelling moles. One common example is the Tangerine Gem variety of French marigold, which has been used as a natural mole repellent for years.

Here is a table that summarizes the different features of the two most common marigold species for mole control:

Species Appearance Scent
Mexican Marigold Small yellow flowers Strong-scented
French Marigold Bright and large orange or yellow flowers Pungent odor

Remember to choose the right species of marigolds based on the characteristics mentioned above to effectively ward off moles. In the next section, we will discuss essential factors to consider when planting marigolds in mole-prone areas.

Plant Marigolds Where Moles are Likely to Infest

Plant Marigolds in Areas Where Moles are Commonly Found

One of the most effective ways to use marigolds as a natural mole deterrent is to plant them in areas where moles are likely to infest. Moles prefer loose, moist soil and are commonly found in garden beds, under shrubs, or along the edges of lawns.

Before planting marigolds, it is important to identify the areas where moles are commonly active in your garden. This may be determined by searching for raised tunnels or mounds of soil, which are telltale signs of mole activity. Once identified, these areas should be prioritized for marigold planting.

It is recommended to plant marigolds around the perimeter of your garden beds, or along the edges of your lawn, as these areas are highly susceptible to mole activity. Additionally, marigolds can be planted under trees or shrubs, which are also common areas for moles to infest.

In order to maximize the effectiveness of marigolds as a natural mole deterrent, it is important to plant them in high density. This means planting marigolds in tight clusters, rather than spaced out individually. This will create a stronger scent barrier, which can effectively deter moles from entering the area.

Planting marigolds in areas where moles are commonly found is a highly effective and simple way to naturally deter moles from your garden. By using marigolds in combination with other natural mole repellents, such as castor oil or garlic, you can effectively create a mole-free environment in your lawn and garden.

Complement Marigolds with Other Natural Mole Repellents

One way to increase the effectiveness of using marigolds as a natural mole deterrent is to complement them with other natural repellents. This can help improve the chances of deterring moles and keep them from infesting your lawn or garden.

Garlic Mole Repellent: Garlic contains sulfur and other compounds that are known to repel moles. You can make a garlic spray by blending garlic bulbs and mixing them with water. Spray the mixture around your lawn and garden to keep moles away.

DIY Solar Mole Repellent: Solar mole repellents emit a high-frequency sound that moles find irritating. These devices are usually made with solar panels and metal spikes that you can place in the ground. They are powered by the sun, so they don’t require any batteries or electricity.

Aluminum Foil: Aluminum foil can be used as a physical barrier to keep moles from burrowing in your lawn or garden. You can place strips of foil around your plants or create a full barrier around the area you want to protect. The foil will reflect light and create noise when moles try to dig, which can deter them from entering.

Plant Bulbs: Certain types of bulbs, like daffodils and alliums, are known to deter moles. They contain compounds that are toxic to moles and other rodents, making them an effective natural repellent. Planting these bulbs in areas where moles are likely to infest can help keep them at bay.

Coffee Grounds: Moles are not fond of the smell of coffee grounds, so scattering coffee grounds around your lawn and garden can help repel them. You can also mix coffee grounds with water and spray the mixture around your plants to keep moles away.

By combining marigolds with other natural mole repellents, you can create a more effective defense against mole infestation. However, it’s important to note that no natural method is foolproof, and you may need to experiment with different repellents to find what works best for your situation.

Use Marigolds as Barriers

Marigolds not only have a strong aroma that can repel moles, but they can also serve as barriers or borders that moles are less likely to cross. To use marigolds as barriers, plant them in a line around the perimeter of your garden or lawn where you want to deter moles. This works especially well if you have noticed a particular area where moles tend to enter or exit your yard.

By planting marigolds in these areas, you can help deter moles and prevent them from coming any further into your lawn or garden. One of the benefits of using marigolds as barriers is that they are easy to plant and maintain, and they can add a pop of color to your garden as well.

It is important to note, however, that while marigolds can be effective as barriers for moles, they may not work in all situations. Some moles may be more determined to cross a line of marigolds if they are really hungry or if they are looking for a specific type of soil or habitat.

For best results, use marigolds as barriers in conjunction with other natural mole repellents, such as castor oil, spicy plants like garlic or cayenne pepper, sound devices, or physical barriers like aluminum foil or wire mesh.

Using marigolds as barriers can be a simple and effective way to help keep moles out of your lawn and garden. Just be sure to consider the other factors that could be attracting moles to your yard, and try to address those issues as well. With a combination of natural deterrents and proper lawn and garden maintenance, you can help create a space that moles won’t want to call home.

Renew Marigolds Every Year

One important tip in using marigolds as a natural mole deterrent is to renew them every year. While marigolds are effective in repelling moles, the effectiveness of the plant diminishes over time. Hence, it is important to regularly replace the old marigold plants with new ones in order to maintain their efficacy.

To ensure that you have a steady supply of marigolds every year, it is recommended to save the seeds from the mature marigold plants and store them in a cool and dry place. When the planting season comes, you can sow the seeds and grow new marigold plants.

Additionally, when renewing your marigolds, it is also a good idea to rotate their placement in your garden. This is because the soil may become infested with moles over time, making it less effective in repelling them. By rotating the placement of the marigolds, you can prevent the moles from getting too accustomed to their presence.

It is also important to note that while marigolds are effective in repelling moles, they should not be used as the sole method of mole control. It is still best to use them in conjunction with other natural mole repellents such as garlic, solar devices, aluminum foil, bulbs, or coffee grounds in order to increase their overall effectiveness.

Avoid Planting Marigolds in Large Tracts

To maximize the effectiveness of using marigolds as a natural mole deterrent, it is recommended to avoid planting them in large tracts. This is because moles may eventually develop a tolerance to the smell of marigolds if they are exposed to them consistently over time. Additionally, planting too many marigolds in one area may also attract other pests that feed on the plant, such as aphids.

Here are some tips for avoiding planting marigolds in large tracts:

  • Interplant marigolds with other flowers or herbs to create a diverse garden landscape. This will spread out the marigolds and prevent them from being concentrated in one area.
  • Plant marigolds in small clusters instead of planting a large block of them. This will create an attractive visual display and also prevent overexposure of moles to the plant’s smell.
  • Consider using marigolds in conjunction with other natural mole repellents, such as castor oil or spicy plants. This will provide multiple layers of defense against moles and reduce the need for a large quantity of marigolds.
  • Rotate the placement of marigolds each year to prevent moles from becoming too familiar with their smell. This will also help to maintain the health of the marigolds by preventing soil depletion.

By following these simple tips, you can effectively use marigolds as a natural mole deterrent without risking overexposure or pests. Remember, a diverse garden landscape is not only aesthetically pleasing but also promotes a healthy and balanced ecosystem.

Keep Your Lawn and Garden Healthy

Maintaining a healthy and vibrant lawn and garden is essential to deter moles and other pests. Here are some tips for keeping your lawn and garden healthy:

Tip Description
Regular watering Proper irrigation and watering will help your plants grow strong and resist damage from pests.
Appropriate fertilization Feeding your lawn and garden with the appropriate nutrients will help them grow robustly, so they are more resistant to pest damage.
Regular mowing Cutting your lawn regularly to a recommended height will keep it uniform and healthy, which will help to deter pests from infesting it.
Prune regularly Trimming back overgrown shrubs and trees will improve air circulation and light penetration, which will help your plants grow stronger and resist pest infestations.
Remove debris Clean up any debris that accumulates in your lawn and garden as it can provide shelter and hiding spots for pests like moles.

By following these tips, you’ll be able to cultivate a healthy and sturdy lawn and garden that is more likely to resist damage from pests. Combining this approach with using natural mole deterrents like marigolds is an effective way to eliminate moles from your yard and garden.

Other Effective Natural Mole Deterrents

Finding the ideal natural mole deterrent is crucial to maintain a healthy garden. While marigolds are a potent solution, some situations may require a more comprehensive approach to rid your lawn of pesky moles. Luckily there are other tried-and-tested alternatives to repel moles from your garden that can complement or replace the use of marigolds. Let’s explore some of the most effective natural mole deterrent solutions.

Castor Oil

One effective natural mole deterrent is castor oil, which has been used for many years to repel moles and other pests. The oil is extracted from the seeds of the castor plant, and it works by smothering the pests and making the soil less appealing. Here are some tips on how to use castor oil as a mole repellant:

  • Mix castor oil with water – The most effective way to use castor oil is to mix it with water to create a spray solution. In a one-gallon container, mix 1/2 gallon of water with 1/2 gallon of castor oil. Stir the mixture well to combine the ingredients.
  • Spray the solution on mole-infested areas – Once you’ve created your castor oil spray, apply it to areas where moles are likely to infest. Spray the solution on your lawn, flower beds, and other areas where you’ve seen signs of mole activity. Be sure to spray a generous amount of the solution on these areas, as moles can be quite persistent.
  • Apply the solution regularly – Castor oil works best when it’s applied regularly. You may need to spray the solution every few days or even every day to keep moles at bay. Be patient, as it may take several weeks before you start to see results.
  • Use commercial castor oil products – If you don’t want to make your own castor oil spray, you can also find commercial products that contain castor oil. These products are often easier to use, as they come in ready-to-spray containers or granular form.

While castor oil is a safe and natural way to repel moles, it’s important to use it properly to avoid unwanted side effects. Be sure to wear gloves and protective clothing when handling castor oil, and avoid getting it in your eyes or mouth. It may be best to avoid using castor oil in areas where pets or children play, as it can be harmful if ingested.

Spicy Plants

Another effective natural mole deterrent is planting spicy plants in your lawn or garden. Moles have a strong sense of smell and don’t like the aroma of spicy plants. Here are some examples of plants that have been known to deter moles:

  • Peppers: Hot peppers like cayenne or jalapeño can be effective in deterring moles. Plant them near mole infested areas or sprinkle some chili powder around the area.
  • Ginger: Planting ginger near the entrance of mole tunnels can also help repel them. You can also sprinkle some ground ginger in and around the tunnel entrances.
  • Garlic: Similar to ginger, planting garlic near the entrance of mole tunnels can help deter them. Garlic can also be grated and mixed with water to make a liquid deterrent that can be sprayed on the affected areas.
  • Onions: Planting onions around your garden or sprinkling onion powder around mole infested areas can also repel moles.

It’s important to note that while these plants can be effective in deterring moles, they should be used in conjunction with other natural mole repellents for best results. Additionally, be careful not to overuse spicy plants as this can have negative effects on other plants and animals in your lawn or garden.

Sound Devices

One other effective natural mole deterrent is utilizing sound devices. These devices work by emitting high-frequency sounds that are uncomfortable for moles, and they are designed to mimic the sounds of predators or other dangers. As a result, moles will often flee the area to avoid the perceived threat.

Here are some popular sound devices for mole deterrence:

Device Type Pros Cons
Solar-Powered Sonic Spikes Easy to install, powered by sunlight, and emit a variety of frequencies to confuse moles Can be ineffective if the mole has already established a burrow system, and may not work well in areas with heavy rain or cloud coverage
Battery-Powered Ultrasonic Repellers Emit high-frequency sound waves that are effective in deterring not just moles, but other pests too May not work well in larger areas and can be costly to maintain due to the need to replace batteries frequently
Wind-Operated Sonic Repellers Efficient and eco-friendly as they do not require any source of power May not be as effective in areas with inconsistent airflow, and the sound may not travel as far as with other devices
Sonic Mole Chasers Generate sound waves that travel through the soil and scare away moles May only be effective for moles in close proximity, and can be noisy to use

It is important to note that sound devices may not be effective if the mole infestation is severe or if the device is not used properly. It is also important to switch up the type and location of the sound devices periodically to avoid moles becoming accustomed to the sound.

Sound devices can be a useful addition to other natural mole deterrents, but should not be relied on solely to solve a mole problem.

Physical Barriers

One effective way to keep moles out of your yard is by creating physical barriers that they cannot cross. This method is especially useful if you have a small garden or lawn. Here are a few ways to create physical barriers:

  • Bury mesh wire: Dig a trench around your garden or lawn and bury mesh wire. Make sure the wire extends above ground by a few inches to prevent the moles from digging under it.
  • Add rocks: Place rocks or stones around the edges of your garden. The moles will not be able to move them or dig through them.
  • Install a fence: Installing a fence around your garden is a great way to prevent moles from entering. Make sure to bury the fence several inches below the ground to prevent the moles from digging under it.

Keep in mind that physical barriers may not be the most aesthetically pleasing solution, but they can be effective in keeping moles out of your yard. It’s important to choose a method that will not harm the moles or other wildlife in your yard.


In conclusion, marigolds are a great natural mole deterrent. They can help keep your lawn and garden free from the unsightly and damaging tunnels that moles can create. Marigolds work by emitting a strong odor that moles find unappealing, thereby driving them away. However, it’s important to note that marigolds alone may not completely solve your mole problem. You may need to use them in combination with other natural deterrents, such as castor oil or sound devices.

When using marigolds as a natural mole deterrent, it’s important to choose the right type of marigold and plant them strategically in areas where moles are likely to infest. You can also use marigolds as barriers and renew them every year. It’s best to avoid planting marigolds in large tracts and to keep your lawn and garden healthy to make it less attractive to moles.

Overall, using natural mole deterrents is a great way to keep your lawn and garden in top shape without harming the environment. By incorporating marigolds and other natural methods, you can successfully keep moles at bay and enjoy a beautiful outdoor space. Take the time to research and experiment with different natural deterrents to find the right solution for your specific needs. Your lawn, garden, and local ecosystem will thank you for it.
