Ants are insects that can easily squeeze into any space. This is why they are commonly found inside our homes. These small invaders, which appear harmless alone, can quickly become troublesome when dealing with a colony.

If your home is severely infested with ants, your best bet is to consult pest control specialists. But if you simply want to know how to keep them away from your home, here are 23 natural repellents that are effective against ants.

23 natural repellents to keep ants at bay

Natural repellents are undesirable products for ants. They usually discourage ants from entering your home and establishing a colony. These techniques avoid the need for pest prevention professionals, even though this type of service is always the most effective.

These products are not intended to exterminate ants, but rather as protection against possible infestations. However, you should consider a professional ant exterminator in the case of a serious infestation.


1. Cinnamon

Whether powdered or in oil form, cinnamon is a great way to keep ants out of your kitchen. You can sprinkle some everywhere, but the golden rule is to do it consistently because the smell fades quickly.


2. Pepper

Other spices can be good natural ant repellents. In fact, ground pepper deters ants and many other insects from entering a home.

All you have to do is sprinkle some in strategic areas to repel these small insects.


3. Salt

Spreading salt near nooks and crannies where ants enter the house will help keep them away. Table salt is one of the best and cheapest ways to naturally get rid of ants.

Use regular table salt, not rock salt, which is better for your health. Simply boil water and add a large amount of salt, stirring until it dissolves. Pour into a spray bottle and spray in areas where you think ants might enter.


4. Lemon juice


Lemon is one of the most effective natural ant repellents, as its acid content impedes the ants’ sense of direction. Spray it along the path of the ants and on door and window openings.


5. Peppermint

Peppermint can help you get rid of ants in your yard by putting a few drops on door and window frames. Another option is to make small bags of dried mint and hang them on the corners of windows.


6. Tansy

A relatively unknown plant in North America, tansy is widely used as a natural insecticide in Europe. If you have some in your garden, chop the leaves very finely to obtain a type of powder.

If possible, pour 10 teaspoons of this powder into 1 litre of ethyl alcohol at 90°C (available in pharmacies) or, if not available, alcohol for fruit liqueurs.

Leave to macerate for about 10 days, stirring the bottle from time to time. The insecticide will then be ready.


7. Garlic

Garlic is also an excellent ant and insect repellent. You can crush a few garlic bulbs, put them in a spray bottle and add water. Let the mixture stand for a few hours so that the water develops a garlic scent.

You can then use the spray on areas where ants roam.


8. White vinegar

Vinegar is a great household cleaning product, but it is also a fantastic way to keep pests away. If ants have entered your kitchen, repel them with a mixture of white vinegar and hot water, in equal portions. White vinegar works for most insects because they can’t tolerate its smell and the acids it contains are toxic to them.


9. Eucalyptus


Simply take eucalyptus oil or water and spray it on the plants in your home. The scent is beautiful and will make your house smell good, while ants will stay away.


10. Cucumber

Peeled cucumber skin is a proven repellent that works its magic by giving off a scent that repels ants. Place the skins where ants usually appear and at the entry points they use.


11. Corn flour

Corn flour has many uses and one of the most effective is as an ant repellent. There is no need to mix it with other ingredients and it can be sprinkled as many times as necessary to keep them away. In addition to wiping out the scent trail left by ants, this product causes the insects to die when they ingest it.


12. Honey

Honey isn’t really a repellent, rather the opposite: ants are attracted by its smell and run towards your products. Which is why you can use it to trap them. Place some in a bowl and wait for the magic to happen.


13. Coffee grounds

Coffee left in the filter has been proven to retain many of its properties. No wonder it is used as a repellent to keep ants and other insects away. The smell is so pervasive that it bothers and repels insects.

Three times a week, mix two tablespoons of coffee grounds in a litre of water and spray the liquid on the problem areas of the house.


14. Boric acid

Boric acid isn’t effective against all species of ants. It is mainly effective against the Argentine ant, the pharaoh ant and the house ant. These ants are small and usually black or red. They are attracted by sugar and inhabit kitchens. Ants that stay outdoors are not as receptive to boric acid baits.


15. Tea tree oil

Tea tree oil repels and kills ants. You can mix 5 to 10 drops of oil with 2 cups of water and use it as a spray. You can also put some on cotton balls and place them where you have seen ants.

Keep it out of reach of pets, especially cats, which can become very sick if exposed to it.


16. Window products

Although not made for this purpose, window products are a solution for neutralizing ants: when sprayed directly on the insect, it becomes paralyzed and dries out. This causes the insect to become dehydrated and unable to do anything.


17. Basil



The smell of basil is effective against many insects and also repels ants. In addition to planting basil in your garden, you can also use dried leaves in a potpourri for indoor use.


18. Borax

Borax is an all-purpose cleaner. Mix it with water and sugar and spread the paste that forms in the corners where you see ants. As with boric acid, do not use it when children or pets can reach it.


19. Diatomaceous earth

Diatomaceous earth (also called diatomite) is composed of fossilized algae that are commonly used as fertilizer. It is found in garden supply stores and has also proven effective against ants and other insects such as fleas and spiders. Like other repellents, it should only be spread where ants usually move around, driving them away without killing them.


20. Chalk

Crossing a chalk line is difficult for ants because it prevents them from following the scents left by other ants that usually guide them on their way. It can therefore be one of the most effective natural deterrents to frighten them, since not only can you block their path, but you can also place chalk “fortresses” as a perimeter around the house.


21. Baking soda

Baking soda is a miracle product that works wonders to keep ants away. For proper use, mix it in a bowl with sugar and pour it into the areas where ants pass by. This mixture releases a substance that is toxic to ants and makes them flee as soon as they detect it.


22. Orange

In addition to lemon, orange is another citrus fruit that is highly effective in keeping ants away from your home. It has a strong odour and will deter ants from venturing beyond your doorstep.


23. Soap

Finally, you can also combine soap and water and lightly spray it on surfaces or areas where you have noticed ants. This will help eliminate scent trails left by ants and discourage others from getting inside.
