Bug-Off: Do Mint Plants Keep Pests at Bay?

Mint plants have been used since ancient times for their culinary and medicinal properties. However, recent studies have shown that these plants may also have the potential to ward off pests. In this article, we will explore whether mint plants actually work as a natural pest repellent and how to use them effectively.

How Does Mint Repel Pests?

Mint plants contain essential oils that have strong scents and insecticidal properties. These oils are released when the plant is disturbed or crushed, and they can interfere with the senses of pests such as mosquitoes, fleas, and even mice.

For instance, one study found that peppermint oil was effective in repelling mosquitoes and helped to prevent bites even when compared to DEET, a common insect repellent. Another study suggested that peppermint oil could be useful in controlling flea infestations in households with pets.

What Types of Pests Can Mint Repel?

Mint plants can help to control a variety of pests, including:

  • Mosquitoes
  • Fleas
  • Ants
  • Rodents
  • Spiders
  • Flies
  • Moths

Do Mint Plants Repel All Kinds of Mosquitoes?

While mint plants can help to repel some species of mosquitoes, they may be less effective against others. For instance, the yellow fever mosquito tends to be less sensitive to essential oils such as peppermint and may require a stronger concentration or a different type of repellent.

How to Use Mint Plants to Repel Pests

Planting Mint:

You can plant mint in your garden to help deter pests. Be sure to plant it in a sunny location with well-draining soil, and keep it watered consistently. You can also plant mint in containers and place them around your home or patio. This can help to keep mosquitoes and other pests at bay during outdoor gatherings or meals.

However, it is important to note that mint plants can be invasive and spread quickly, so it’s important to keep them contained or to plant them in a dedicated herb garden.

Making DIY Pest Repellents:

You can also use mint plants to create your own natural pest repellents. Here are some recipes to try:

Homemade Flea Spray:

  • Boil 2 cups of water and add two lemons, sliced.
  • Let the mixture steep for a few hours, then strain it into a spray bottle.
  • Add 10-15 drops of peppermint or spearmint essential oil, and shake well.
  • Spray the mixture on your pet’s fur, bedding, and anywhere else you suspect fleas may be hiding.

DIY Mosquito Repellent:

  • Fill a spray bottle with ½ cup of water and ½ cup of witch hazel.
  • Add 10 drops of peppermint essential oil, 10 drops of lemon eucalyptus essential oil, and 5 drops of cedarwood essential oil.
  • Shake well and spray on your skin or clothing before going outdoors.

Are There Any Risks or Side Effects of Using Mint as a Pest Repellent?

While mint plants are generally considered safe, there are a few precautions to keep in mind:

  • Mint plants can be toxic to certain pets, such as cats and dogs, so be sure to keep them out of reach.
  • Some people may be sensitive to or allergic to mint, so it’s a good idea to test a small amount of any DIY repellent on your skin before using it more widely.
  • Peppermint oil and other essential oils should be used with caution around children and pregnant women. It’s best to consult with a healthcare provider before using essential oils during pregnancy or with infants and young children.


Mint plants can be a useful tool in controlling pests naturally. Whether you plant them in your garden or use them to make DIY repellents, there are many ways to incorporate mint into your pest control strategy. Just be sure to keep in mind the potential risks and side effects, and consult with a healthcare provider or veterinarian if you have any concerns.
