Getting rid of ants can be tricky, especially when they infiltrate your yard and garden. According to the National Wildlife Federation, there are over 12,000 different species of ants throughout the world.

Certain species of ants can devour ornamental plants and destroy vegetable gardens or fruit trees. Worse, ants in your garden can mean that ants are that much closer to getting into your home.

In today’s article, we are going to discuss how to deal with ants in the garden the natural way! Join us as we take a look at 10 plants that repel ants.

Companion planting can repel ants by disrupting their sense of smell.

There are quite a few plants that ants, and many other insects for that matter, are attracted to. Equally as important, there are several types of plants that ants and other insects are repelled by.

The secret is in the scent.

Like most insects, ants rely heavily on their sense of smell. They use this sense of smell to not only navigate the world around them and detect dangers, food, and environmental changes, but they also use it to communicate.

Ants in particular are expert communicators via scent. In fact, ants leave behind a scent trail to help lead other ants in their colony to food, safety, and shelter.

Disrupting this sense of smell disrupts one of the ant’s most important senses, so it comes as no surprise that strong-smelling plants can deter these pests.

Some of the best plants that repel ants include mint, rosemary, thyme, lavender, common yarrow, tansy, pennyroyal, basil, onions, and garlic.

Of course, it’s one thing to know which plants deter ants, but it’s another thing to know exactly how to use them appropriately to get rid of these pesky pests.

Because mint is both beautiful and easy to grow, it is one of the most highly recommended plants that repel ants on our list.

To use mint as a repellent plant in your garden, it’s best to plant the herb in moist soil that has good drainage and is not too wet. If you are planning on growing mint in your garden, you won’t need to plant more than one or two plants.

Rosemary is not as easy to grow as mint, but it is still a highly recommended plant when it comes to plants that repel ants.

To successfully use rosemary in companion planting for pest control, plant it in sun-rich areas in well-drained soil. Plant the herb at least two to three feet apart from other plants. Rosemary is an evergreen plant, and it blooms with lovely blue, white, or pink flowers during late spring and early summer.

Though rosemary is one of our plants that repel ants, you should note that it can attract honeybees.

Tips And Tricks For Keeping Ants At Bay In The Garden

Removing aphids can help reduce ants, as can a number of other steps.

Ants are certainly a nuisance, and they can even be costly if they get into your home. Taking care of ants in your garden is one way to help ensure ants don’t make their way inside, but getting rid of them in the garden can be just as tricky as getting rid of them in your home.

Using companion planting as a method to get rid of ants is an effective and natural method we love for pest control, especially when used in conjunction with some of our listed products above.

Of course, we always like to say that prevention is key to any pest control regimen, and the same is true for keeping ants out of your garden.

Here are a few tips and tricks you can use to keep ants from becoming a nuisance in the future.

Remove Pests Like Aphids

Ants and aphids have a symbiotic relationship in which the aphids help provide the sweet secretion of honeydew that ants love. In turn, ants protect the aphids. Unfortunately, this relationship can mean more aphids in your garden, which can be harmful to your plants.

Getting rid of aphids can reduce the attraction your garden has to ants, and it can also help prevent damage to your plants.

Utilize Companion Planting

As we’ve covered, utilizing companion planting is a common way to not only repel ants but also to prevent them. The more you can work to make your garden less attractive to ants, the better off your garden will be.

Invite The Predators

A great way to get rid of ants is to invite their predators to your garden. Ants have a number of natural predators you might consider allowing to move in, including spiders, snakes, lizards, and birds.

Last, Consider Letting Them Stay!

Yes, this does seem counterproductive to the entire article, but in smaller numbers ants can actually be beneficial to your garden. Ants can help your garden thrive by aerating the soil when they dig tunnels below the earth.

However, not all species of ants are beneficial to gardens, and large numbers of ants can do more harm than good.

If you’re struggling with ants in your garden, we highly recommend utilizing the methods listed above to control them.
