So which oils do you need? First, a carrier oil like olive, sunflower, or coconut to dilute and distribute the essential oil, making it last longer and buffering potential irritation. (The latter actually has mild insect-repelling properties in itself.) Then comes the essential oil. Citronella, lemon eucalyptus, clove, thyme, lemongrass, and peppermint oils will all prevent mosquito bites (and smell nice!).
Mix 25 drops of essential oil for every two tablespoons of carrier oil and apply to your skin like lotion, or put them in a spray bottle. “Blending a broad range of oils can help,” says Brighten. “When hiking you may want to repel ticks and mosquitos, so you could use a mixture of citronella and rose geranium.” (Some people may still react to essential oils, so as always, test a small patch on your arm before applying anything all over your body.)
Make sure you can use, please check with your TX people.
