Home Remedies for Ants

1. Boiling Water

Boiling Water

If you see ant holes close to your home, you can pour boiling water into them. This is an effective way of killing ants right away. It might not be enough to kill the entire colony, but many ants will still get killed.

2. Borax

Borax is an effective killer to various ant species, such as sugar ants, carpenter ants, and even fire ants. However, you should mix it with the favorite food of ants, such as sugar. 

Just add:

  • 1/2 cup of water
  • 1.5 tablespoons of borax
  • 1.5 cups of warm water

Mix all the given ingredients and make sure they blend well. Once done, put the bait near the ants’ mound to consume. This interferes with the digestive system which will eventually kill them.

3. Chalk


Another option you have in getting rid of your ant dilemma is by using chalk. Its calcium carbonate content will repel ants due to its compressed marine animals’ shell composition.

Simply draw a line to the entry points, and it will prevent the ants from crossing your property. Scattered powder chalk in the garden is also a great way to keep ants away from your plants

4. Citrus

Citrus, such as grapefruit, orange, lemon, and lime works best in deterring ants by covering their scent trails temporarily. Just get a clean spray bottle and squeeze citrus into the bottle.

Spray it to the affected area, at entry points, and where you frequently see ants. You can also wipe the purred orange peel and water blend to door jambs and window sills.

5. Coffee Grounds

Coffee Grounds

Coffee grounds have been a great ant-repellent for many years already. Just sprinkle the coffee grounds, particularly around the stems of your flowers and plants. The intoxicating smell of coffee repels the ants and its acidity causes them to feel discomfort while walking over it.

6. Cornmeal and Boric Acid

Cornmeal is great food for ants. Thus, it would make a great bait if mixed with boric acid. Just mix one portion of boric acid into nine parts of cornmeal. After that, add a substantial amount of soybean oil or peanut butter to make a paste.

Put the homemade bait close to gaps and crevices or where you frequently see ants. Make sure to keep this inducement away from animals and kids.

7. Diatomaceous Earth

Diatomaceous earth comprises diatoms—the fossilized remains of aquatic organisms. This kills ants by consuming the oils of their skeletons, dehydrating them, and leaving them to die.

However, since diatomaceous earth is an irritant, make sure you won’t breathe it or get it on your skin. To apply this, sprinkle it directly into the ants or their mounds or nests.

8. Essential Oils

Essential oils, such as peppermint, lavender, neem, and tea tree oil, are excellent deterrents to ants. All you need to do is mix your chosen oil with water and spray it directly in the affected areas.

You can use any of the following oils:

Tea Tree Oil 

Tea tree oil is known to kill and repel ants effectively. To make the tea tree solution:

  • Step 1: Get 2 cups of water and mix it with 5 to 10 drops of water.
  • Step 2: Once done, put the mixture into a clean spray bottle and spatter it on the ants or in the suspected areas.

You can also soak cotton balls with tea tree oil and put them around the place where you frequently see them. If the odor is too strong, you can blend tea tree oil with water and peppermint. Make sure to keep the tea tree oil away from your pets as they can get very ill when exposed to it.

9. Flour

Using flour is convenient in keeping ants off their tracks. Just apply a substantial amount of flour at window sills or across the foundations of your home. Moreover, you can also use a sifter to apply flour dusting directly on their path to intrude their pheromone trail.

10. Fresh Mint

Fresh Mint

Ants dislike the strong aroma of fresh mint. So, planting it around your house can discourage ants from entering your place while giving off a pleasant scent to your surroundings.

You can also opt for minty essential oils, such as:

  • Thyme
  • Rosemary
  • Peppermint
  • Wintergreen
  • Clove
  • Geranium

11. Lemon Juice

Another natural option you have to get rid of ants in your place is by using lemon juice. To apply:

  • Step 1: Spurt some lemon juice on windowsills and door thresholds.
  • Step 2: Squeeze the juice into cracks and holes that serve as entry points to ants.
  • Step 3: After that, scatter the tiny slices of lemon peels in your outdoor entrance.

12. Pepper


Although pepper doesn’t eliminate your ant problem, its strong odor discourages them from coming to your place again. In addition, this also erases the scent trail that gives ants direction to find their food.

To use pepper, get a clean spray bottle and add enough water. After that, add pepper and spray it on the entry points to keep ants at bay. You can also follow ant trails so that you can discern their nests right away and spray at them too.

13. Sugar

Since ants like sugar, it’s an ideal bait to lure these pests and inflict significant damage to their colony. To do this:

  • Step 1: In a mixing bowl, mix equal parts of sugar and baking soda.
  • Step 2: Once done, place it near the ants’ mounds or where a line of ants is present. They will carry the bait into their nest and eat it.

14. White Vinegar

Use three parts of white vinegar and one portion of water. Mix the two thoroughly and put the mixture in a bottle spray. After that, spray it to the affected area or in places where you frequently see ants crawling. Prioritize spraying the doorways and yard.

You can also use this to mop your floor as this is a good disinfectant, apart from being a good repellent to ants. Just mix a bit of white vinegar into a bucket of water, and you’ll have your disinfectant plus insect repellent.
