Homemade Bug Spray - Natural Recipe - 3 Ingredients

With the arrival of summer heat, mosquitoes also show up. Store-bought bug sprays are known to be full of heavy chemicals in their composition. Fortunately, it is possible to make a homemade natural repellent with simple herbal ingredients. We will show you how we quickly make our bug spray with 3 ingredients only. See our educational video at the end of the post.

Here's our recipe:


  • 1 Cup Peppermint (fresh leaves). You can use other herbs that have mosquito repellent action, such as basil, lavender, lemon balm, lemon grass, lemon thyme, spearmint, rosemary, and sage. 
  • 1 Cup Water
  • 1 Cup Witch Hazel. Witch Hazel (Hamamelis extract) is a plant (shrub or small tree) with soothing and regenerative properties for the skin, in addition to having insect repellent action.  Witch hazel can be found here.

This recipe gives about 350ml of spray. The smell is very mild for humans but it is enough to keep mosquitoes an other bugs away. For those who like more fragrant products it is possible to add a maximum of 10 drops of peppermint essential oil or one of the other plants mentioned above.

How To Make It?

  1. Boil peppermint leaves in water for 10 minutes.
  2. Remove from the heat, cover, and let cool.
  3. Strain and pour into a spray bottle.
  4. Add witch hazel to the bottle. 
  5. Shake the bottle to mix well.

How To Use?

Spray and spread on the skin as often as needed. Because it is a natural product, it may be necessary to apply more frequently than chemical sprays.

How To Store?

Store in the refrigerator up to 1 year. Witch hazel contains preservative alcohol in its composition, which also contributes to a longer shelf life.

Very Important Notes

If you use essential oils, make sure you don't use essential oils of citrus fruits if you are going to be exposed to the sun after applying the spray. Although bugs don't like citrus smell, citrus fruits essential oils are photosensitive and will stain your skin.

This spray is very mild and soft on the skin and we believe it is suitable for European mosquitoes. If you are in a tropical country or if you travel to a tropical destination where malaria, dengue, and other aggressive mosquitoes are present, please do not use a homemade all-natural bug spray, as sad and frustrating as it may be.  Use a strong spray and just make sure you stay safe and keep dangerous diseases away from you and your family.

With this bug spray we hope you can have a more natural and peaceful summer. Watch our video where we show how to make this bug spray step-by-step.
