They do not feed on grass but can ruin your plants in different ways. The mounds of soil that ants create can smother and kill grass plants. The land that surrounds the mound can dry out, which can also kill the plants. 

Ants also feed on newly planted grass seeds, and sometimes they store seeds in their homes. Having these mounds on your lawn may be a nuisance because it can also ruin the look of your lawn. It may also be hard to mow it because of the mounds you may encounter along the way.

Carpenter ants are the number one ant species that can damage your home. When ants are eating away in your home, it can get gruesome as time passes by. Carpenter ants do not usually travel far from their nests to find food.

How to Control Ants in Your Garden

There are a lot of ways on how you can prevent ants from ruining your plants.

Inorganic Mulch

One example is using inorganic mulch such as crushed rocks, ground-up tires, or synthetic landscape fabric to avoid attracting ants to your plants.

Insect Repellent

You can also create your insect repellent at home. Ants are sensitive when it comes to odors. Just like they are attracted to sweet, certain smells can repel them. They hate the smell of mint, camphor, and clove oil. 

Ant Repellant Plants

You can test these smells in a small cotton ball and see which one is the most effective. Another great way is to plant ant repellant plants in your garden, which will be mentioned below. You can also blend some hot peppers and place them on a towel and wipe the affected areas.

Cover the Mound

Fire Ants are probably the most destructive species. They do not only hurt your plants, but their bites can be very painful. To destroy a Fire Ant mound, cover the mound with a container and pour boiling water around the container. 

  • Once you have done that, wait one minute. Turn over the container with a stick and pour another gallon of boiling water into the ants seeking refuge. Repeat this process until all of the ants are completely removed.

Plant Flowers

Another plant that ants are attracted to are flowers that are rich with nectar as well as sweet fruits. Although ants do not hurt plants, gardeners would not want a lot of ants swarming on their plants. 

Sticky Traps

One thing that you can do to repel ants on your flowers and fruits is to use sticky traps. This would prevent the ants from climbing on the plants. You buy these sticky products in the market such as Tanglefoot or create them yourself. 

Borax Powder

Ant colonies are another significant problem that you would need to face when you have a garden. Baits laden with insecticides are more likely to target ants instead of your plants. You can mix a cup of borax and a cup of honey near the ant activity.

  • The ants will feed on this toxic and will bring it back to the queen ant. Thus, this will result in the death of the colony. This method may take a lot of patience for you to see the results. It takes time for the ants to distribute the toxic in their homes.

Now, if the homemade solution is too much work or a bit too messy for you, it is always a great idea to purchase a ready-made boric acid ant bait.

Plants That Ants Avoid

As mentioned above, ants are very attracted to anything sweet. However, there are also those plants that ants avoid. This is because of the smell that these plants have. The ant’s least favorite scent is mint.

Here are a couple of plants that you can place in your garden so that you do not have to worry about ants infesting your flowers or fruits.


This herbal plant is part of the mint herb family and can grow up to three feet high. You should place dried catnip on the location where you think ants can enter, such as windows and doors. Putting dried catnip works like a charm, and you do not need to worry about your ants ruining your plants or entering your home.

On your plants, however, it is excellent to plant catnip with your flowers, vegetables, and fruits. This will prevent the ants from climbing your crops.


Pennyroyal has leaves that are slightly hairy and narrow, while mauve or white flowers grow in tiers of clusters. It has a strong peppermint scent and does best in moist soils. This plant is known to deter mosquitoes and fleas, which is why it is best to grow in damp places. 

Just like catnip, it is best to place dried pennyroyal inside your home where you think ants can get in. Due to its strong mint smell, it can repel any ant species that may get in your home or your plants.


If you already used all of the insecticides and pesticides available, and the ants keep coming, sage is your answer. The strong smell that sage possesses repels the ants that may be a harm to your plants. You can grow sage in your garden to protect your other plants. 

Unlike the pennyroyal and catnip, it is best to place fresh sage in your home instead of it dried up. You can place this herbal plant in different places in your home as well.


Ants can be a curse and a blessing at the same time. They can be a great help to your plants by getting rid of any insects that may ruin them.

However, there are other species where they can destroy your plants by building their colony near them. Mounds on your lawn can kill the grass by having dried soil around the entrance of the ant’s home. This would prevent the grass from growing. Some ants feed on seeds, or they will bring the seeds in their nests. Using home remedies and planting plants that repel ants are the best solution in case of infestation. Ants can damage your plants, homes, and lawns, but this is a part of their daily lives. Knowing the right prevention and solution is the best way to avoid any infestations that you may face.
