Fortunately, you don’t need to resort to harsh chemicals to reclaim your space. Here are ten effective, natural, and easy-to-make ant repellents that will help keep your home ant-free.
1. Vinegar and Water Solution
Vinegar disrupts ant pheromone trails, making it difficult for them to navigate.
Ingredients:
- Equal parts white vinegar and water
Instructions:
- Mix the vinegar and water in a spray bottle.
- Spray the solution directly on ants and along their trails.
- Wipe the area with a clean cloth after a few minutes.
Pro Tip: Regularly spray entry points like windowsills and door frames to deter ants from entering.

The acidic property of lemon juice masks ant scent trails.
Ingredients:
- 1 part lemon juice
- 3 parts water
Instructions:
- Combine lemon juice and water in a spray bottle.
- Spray the mixture around entry points and areas where ants are active.
Pro Tip: Place lemon peels near entry points; the d-limonene in the peels kills ants on contact.

This mixture attracts ants, and the baking soda disrupts their digestive systems.

Instructions:
- Mix the baking soda and powdered sugar.
- Place small amounts in shallow containers near ant activity.
Pro Tip: Ensure pets and children cannot access the bait.
5. Borax and Sugar Solution
Borax is toxic to ants and, when combined with sugar, lures them in.

- 1/2 cup water
- 1 tablespoon borax
Instructions:
- Mix sugar, water, and borax until dissolved.
- Soak cotton balls in the solution and place them near ant trails.

6. Dish Soap and Water Spray
Dish soap breaks down ants’ exoskeletons, killing them on contact.
Ingredients:

Instructions:
- Combine dish soap and water in a spray bottle.
- Spray directly on ants and wipe the area clean after a few minutes.

7. Ground Black Pepper
Ants find the smell of black pepper irritating and avoid areas treated with it.
Instructions:

Pro Tip: Use this method in conjunction with other repellents for best results.
8. Diatomaceous Earth
This natural powder dehydrates ants upon contact.
Instructions:

The strong scent of coffee grounds can deter ants.
