Flies 6

Have you ever been bothered by a swarm of flies while trying to enjoy a peaceful afternoon at home? If so, you’re not alone. Flies can be a nuisance, especially during the warmer months. But don’t worry, there’s a natural, effective solution to your problem – peppermint oil. This blog post will provide an in-depth guide on how to keep flies away with peppermint oil, a natural and safe method that has been proven to be effective.


To keep flies away with peppermint oil, you can create a homemade spray by combining 50-100ml of distilled water, 50-100ml of white vinegar, and 10-20 drops of 100% pure peppermint essential oil. Alternatively, you can use a diffuser or apply the oil to cotton balls and place them in areas where flies are common. Always remember to dilute the oil before use to avoid skin irritation or damage to surfaces.

Why Peppermint Oil?

Peppermint oil is a potent essential oil derived from the peppermint plant, which is a hybrid of water mint and spearmint. Known for its strong, refreshing scent, this oil is not only pleasing to our senses but also highly effective in repelling various types of flies. Research has shown that flies, such as Drosophila suzukii (fruit flies) and Musca domestica (houseflies), are particularly averse to the smell of peppermint oil. One study even found that peppermint oil remained 100% effective in repelling fruit flies for up to six days post-application!

How to Use Peppermint Oil to Repel Flies?

Peppermint Oil Spray

One of the easiest ways to use peppermint oil as a fly repellent is to create a spray. Here’s a simple recipe:

  • 50-100ml of distilled water
  • 50-100ml of white vinegar
  • 10-20 drops of 100% pure peppermint essential oil

Combine these ingredients in a glass spray bottle, shake well, and voila! You have a homemade, natural fly repellent. Spray this mixture around your home, especially near windows and doors. Remember to shake the bottle before each use to ensure the oil is well distributed.

Peppermint Oil Diffuser

Another method is to use a diffuser. Add a few drops of peppermint oil to your diffuser and let the scent permeate your home. This method is not only effective in repelling flies but also creates a fresh, invigorating atmosphere.

Peppermint Oil on Cotton Balls

For a more localized solution, apply a few drops of peppermint oil to cotton balls and place them in areas where you often see flies. This could be your kitchen, dining area, or near trash cans.

Precautions When Using Peppermint Oil

While peppermint oil is a safe and natural method to repel flies, it’s important to take some precautions. Always dilute the oil before use to avoid skin irritation or damage to surfaces. If you’re using the oil for the first time, test it on a small, inconspicuous area first. Also, keep the oil out of reach of pets, as some essential oils can be harmful to them.

Where to Buy Peppermint Oil?

You can purchase peppermint oil from various sources, such as Amazon, Walmart, Target, or GNC. When buying, ensure the oil is 100% pure, derived from Mentha arvensis or Mentha piperita plants, and packaged in a dark-colored glass bottle to maintain potency. Always do your research and choose a reputable brand.


Peppermint oil is an effective, natural solution to keep flies away from your home. Whether you choose to create a spray, use a diffuser, or apply the oil to cotton balls, you’re sure to appreciate the fly-free environment and the fresh, minty scent. So, the next time flies try to invade your space, arm yourself with peppermint oil and enjoy your peace.
