23 Natural Ways to Get Rid of Ants in Garden

Insects that serve a useful purpose in some cases; in forests and parks, ants can keep all kinds of harmful pests under control.

However, they can quickly become a nuisance, as they can kill other useful insects in your garden and wreak havoc on your plants. Ants can also attract other harmful insects like aphids.

The use of traditional insecticides might kill them, but they can pose serious health risks and other bugs and plants.

Read on to learn how to get rid of ants in the garden naturally.

Most of these remedies use natural and organic ingredients you likely have in your kitchen already!

1. Lemon juice

The acidic qualities in lemon juice will mask the natural odors ants love, which makes it hard for them to navigate their surroundings.

Spray lemon juice on around your garden beds to throw them off track or leave cotton balls soaked in lemon juice in ant-infested spots.

2. Cinnamon

Cinnamon powder is an easy and effective way to deter the critters from coming into your garden and house. They despise the smell and will avoid coming near it.

Sprinkle cinnamon around beds and nursery areas or place the sticks around your plants.

3. Peppermint Oil

Like other strong smells, peppermint interferes with their ability to communicate.

If it cannot communicate, it loses track of its surroundings and cannot find its way back to the colony, and will die.

Spray a peppermint oil solution around plants or plant a few peppermint trees nearby.

4. Borax and Sugar

This is a highly sought-after remedy for those seeking how to kill ants in garden soil. Borax is safe for use in the lawn, your home, and garden but toxic to the critters.

Mix some borax with a bit of sugar or honey.

The sugary scent will attract them and the solution acts as a poison that they will carry back to the colony, wiping it out entirely.

5. Boiling Water

One of the simplest ways to destroy their colony is to pour boiling water directly onto the mound.

Boiling water will also kill the surrounding grass and plants, so try to avoid spilling the water on your crops.

6. Diatomaceous Earth

Food-grade diatomaceous earth acts as a natural abrasive to crawling insects.

Pour it directly onto nests or wherever there is a trail.

Just be careful not to apply it to flower petals (flower beds are fine), especially where bees might land.

7. Cucumber Peels

Another cool method to remove ants from the garden is with the use of cucumber peels.

They are naturally averse to the taste of cucumber, especially bitter ones.

Sprinkle a few peels around your orchard, replacing them every couple of days until the army disappears.

8. Baking Soda and Powdered Sugar

This is an effective and harmless solution that you can also sprinkle on ant nests.

The powdered sugar will lure them, while the baking soda will interfere with their digestive systems.

9. Cornmeal

The pests will happily eat cornmeal, even though their bodies cannot digest it.

Their bodies will swell and they will eventually die as a result.

Sprinkle it in nests if your garden is overrun with ants.

10. Coffee Grounds

Coffee grounds also act as a protective barrier for plants or flower beds, as the scent of coffee prevents ants from following their own scent trail.

Next time you make coffee, sprinkle the remaining grounds around your plant beds.

11. Cream of Wheat

Cream of wheat has a similar effect that cornmeal does. Their bodies cannot digest it and they will die after ingesting it.

Place small pieces of the cereal around areas they’ll likely show up to attract and kill them.

12. Vinegar

This is not only a simple and effective natural pest control remedy for everyday nuisances, but it is also an effective method for repelling these ones.

Spray vinegar directly on the hills. They detest the smell of vinegar and will avoid anything that is sprayed with it.

13. Cayenne Pepper

Sprinkle cayenne pepper around your garden. The strong smell interferes with the ants’ ability to communicate.

This means that they will not be able to find their way home, and therefore will not survive.

14. Citrus Peels

The critters are naturally repelled by the smell of citrus.

Allow the peels of oranges, grapefruits, or lemons to dry out for a couple of days, then grind them into a fine powder in your food processor.

Sprinkle the powder around plants to act as a protective barrier.

15. Tea Tree Oil

This is another effective remedy to fix an ant problem.

Simply place a few drops of oil on their trails leading to your farm, and they will avoid that area.

16. Clove Oil

Clove oil is one of the most effective ant control remedies as it kills them on contact.

Make your own natural insecticide by mixing a few drops of clove oil with a quart of water.

Spray the solution on nests or on areas where they will have contact.

17. Bay Leaves

Will bay leaves get rid of ants? Certainly. The strong smell of bay leaves keeps them away but it will not kill them.

Crush and sprinkle a few leaves around and they will not come near them.

18. Garlic

Use garlic to drive away all kinds of pests and insects, but particularly ants.

They do not like the smell and will not go near it.

Just place a couple of raw garlic cloves wherever they are most active.

19. Red Chili Powder

This spicy powder acts as a natural ant killer that will burn or suffocate them.

Sprinkle chili powder around plants or directly onto the hill.

20. Flour

They do not like anything dry and powdery.

Sprinkle flour around your vegetable beds or plants and they will keep away from that area.

21. Soap Water

Soap and water mix is one of the most effective control methods, as it suffocates them.

Make a simple solution of equal parts organic liquid soap and baking soda and spread it over any areas where they are getting in.

22. Salt

A sprinkle of table salt on areas frequented by them, or on the hills directly, is another effective home remedy.

Consuming salt will cause them to lose water and eventually die of dehydration.

23. Molasses and Orange Oil

This is another of the popular natural home remedies for ants. While molasses does not kill them directly, it masks the insecticidal properties of other substances like borax.

Combine molasses with borax or baking soda and place a few spoonfuls of the mixture directly onto their hills or trails.

Types of Ants

Although there are over 12,000 species, there are three main types that you should know about.

1. Carpenter

Carpenter ants are common garden insects. One nest can contain thousands of them.

They are beneficial as they contribute to the composting of rotten wood.

They can feature different colors — red, black, brown, orange, yellow, or black and red coloration.

2. Leaf-Cutting

Leaf-cutters are large ants that live in crescent-shaped mounds above ground or large underground colonies.

These are bad critters as they attack shrubs, trees, and plants. They range in color from brown to red to black.

3. Fire

You’ll likely find these in your vegetable garden bed and lawn more often than others.

Fire ants are quite large and can inflict painful bites. In some cases, they can cause severe allergic reactions in humans.

They too will attack your crops. Their color ranges from reddish-brown to reddish-black.
