6 Pure Essential Oils for Repelling Mosquitoes

18 March 2019, Dominique Callahan

In the perpetual hot and humid climate in Thailand, mosquitoes are active all year long. DEET products contain chemicals that many believe are harmful to humans as well as other species. Fortunately, many essential oils act as natural mosquito repellents and, importantly, they are safe for both pregnant women and young children.

To avoid exposure to toxic chemicals and to stay safe from mosquito bites, there are some pure essential oils that you can apply instead of store-bought sprays or lotions. In addition to their bug-repellent properties, they offer numerous health benefits. Additionally, they are all readily available in Bangkok, as they can be found at markets such as Chatuchak Weekend Market or at local retailers such as Siam Botanicals and Novessence

DIY Mosquito Repellent

To get started, we focus on lemongrass, rosemary, lavender, geranium, cinnamon, and tea tree. Get a clean glass spray bottle, and add 25 to 30 drops of these essential oils (any combination will work), depending on your preference. Then shake to mix. Next, put in half a cup of witch hazel (also available from Siam Botanicals or from Lazada) and shake again, adding half a cup of distilled water.

Tips on Using Your Homemade Mosquito Repellent

  • Shake well before each use as the water and oil may separate over time.
  • Avoid spraying on face, eyes, mouth and other sensitive areas.
  • For young kids, spray the mixture on their clothing or gear (instead of directly on their skin).

If you have leftover oils, you can use them for their additional healing properties, as listed below.

The safest way to use these oils is to diffuse them into the air with a steam diffuser in a particular room. Just be sure that you leave enough time for the oil’s scent to dissipate before allowing your children into the space. In some cases, the oil can be applied topically to the skin in tiny amounts, or in some specific cases even consumed (please consult the brand and label first!).
