What Essential Oil Repels Ants?

Ants 5

Essential oils are known for their numerous health benefits, but did you know they can also be used as a natural way to repel ants? Ants, while not typically dangerous, can become a nuisance when they invade your home in search of food. In this comprehensive guide, we’ll explore the various essential oils that can effectively repel ants and how to use them.


Several essential oils are known to repel ants effectively. These include peppermint oil, clove oil, cinnamon oil, citrus oils (like sweet orange, grapefruit, and lemon), tea tree oil, eucalyptus oil, lavender oil, and spearmint oil. They can be used in a spray mixture or soaked in cotton balls and placed near ant trails. However, their effectiveness may vary, and they should be used cautiously.

The Power of Essential Oils Against Ants

Essential oils are extracted from plants and capture the plant’s scent and flavor, or “essence.” Certain essential oils are particularly effective at repelling ants due to their strong scents and specific chemical compounds. Here are the top essential oils known to repel ants:

  1. Peppermint oil: The strong scent of peppermint oil is unappealing to ants and disrupts their ability to locate food sources.
  2. Clove oil: Clove oil has insecticidal properties and a strong, spicy aroma that can mask the pheromones ants use to communicate.
  3. Cinnamon oil: Ants dislike the scent of cinnamon oil, making it an effective repellent.
  4. Citrus oils: Oils such as sweet orange, grapefruit, and lemon contain d-limonene, which is toxic to ants and erases their chemical trail.
  5. Tea tree oil: Known for its strong and pungent aroma, tea tree oil is highly effective against ants and other pests.
  6. Eucalyptus oil: This oil has insect repellent properties and a strong, refreshing aroma that ants dislike.
  7. Lavender oil: The calming scent of lavender oil also has insect-repelling properties that can deter ants.
  8. Spearmint oil: Similar to peppermint oil, spearmint oil has a strong scent that repels ants.

How to Use Essential Oils to Repel Ants

To use essential oils as an ant repellent, create a simple ant-repellent spray. Combine 30-40 drops of essential oil (such as peppermint, tea tree, or citrus oil) with 30 drops of alcohol and 60 ml of distilled water in a spray bottle. Shake the mixture well and spray it around areas where ants are common. Avoid spraying in the kitchen or on surfaces where you prepare food.

You can also soak cotton balls in the oil and place them near ant trails or in affected cabinets and storage containers. Replace the cotton balls every two days until the ant invasion recedes.

Potential Risks and Side Effects

While essential oils are natural, they can cause side effects in some individuals, such as headaches, rashes, and other sensitivities. Peppermint oil should be avoided for children under six and pregnant or breastfeeding women. Citrus oils, such as sweet orange oil, contain d-limonene, which is toxic to ants and erases their chemical trail. However, excessive amounts of these oils can be toxic to humans, so it is essential to use them in moderation.

The effectiveness of essential oils as ant repellents may vary depending on the type of ant and the specific oil used. Essential oils are categorized as “minimum risk pesticides” by the EPA, meaning they do not undergo rigorous testing for safety and effectiveness.

Comparing Essential Oils to Traditional Ant Repellents

Traditional ant repellents often contain chemicals that can be harmful to humans, pets, and the environment. In contrast, essential oils are natural, non-toxic alternatives that can be used safely in most cases. However, their effectiveness may vary depending on the type of ant and the concentration of the oil used.

Where to Buy Essential Oils

Reputable sources and brands to purchase essential oils include Plant Therapy, The Vitamin Shoppe, Vitruvi, Rocky Mountain Oils, Pura D’or, Aura Cacia, Edens Garden, Saje Natural Wellness, doTERRA, Young Living, Aromatics International, Art Naturals, and Garden of Life. These brands are known for their high-quality, pure essential oils, and commitment to sustainability and ethical practices.


In conclusion, essential oils can be an effective and eco-friendly alternative to traditional ant repellents. However, their effectiveness may vary, and they should be used cautiously. Always remember to keep essential oils out of reach of children and pets and avoid direct contact with skin and eyes.

Frequently Asked Questions

Can I use a mix of different essential oils to repel ants?

Yes, you can mix different essential oils to create a more potent ant repellent. However, remember to maintain the recommended ratio of essential oil to alcohol and water when creating your ant-repellent spray.

How often should I spray the ant-repellent mixture?

You should spray the ant-repellent mixture daily in areas where you’ve noticed ant activity. Continue this until you no longer see any ants.

Can essential oils harm my pets?
