Opt for a scented dryer sheet: lavender and lemon balm are great options. Simply put one in your pocket or wrap it around a belt loop to naturally keep gnats away.  In addition to keeping away gnats, the dryer sheet may also help repel mosquitos. If your outfit doesn’t have a pocket or belt loops, you could pin it to your clothes. It might look a little silly, but it should help! It turns out that gnats hate the smell of vanilla! Mix together 1⁄2 teaspoon (2.5 mL) of vanilla extract and 1⁄2 teaspoon (2.5 mL) of water. Put the mixture onto a cotton ball and rub it on your neck, wrists, collarbone, and ankles. If you’re going to be outdoors for a long time, bring a small container filled with extra extract to reapply throughout the day. In a small, clean container, mix together 1⁄2 cup (120 mL) of shea butter and 4-6 drops of peppermint essential oil. Rub the cream onto your hands, neck, legs, arms, and any other areas of exposed skin. If you don’t have shea butter, use another moisturizer that doesn’t have added scents. Sometimes, no matter how hard you try to avoid it, you might end up walking through a heavily infested gnat area. To keep them away from your eyes, mouth, and nose, wear a pair of sunglasses and wrap a bandana around your face. Once you’re away from the area, you can remove these items. Gnats won’t harm you—they don’t bite or transmit diseases—but they are annoying and can ruin a nice day. Do your best to be prepared when you go outdoors, especially if you’ll be near still water sources.

Summary:
Keep a dryer sheet in your pocket to repel gnats while you’re outdoors. Dab on a few drops of vanilla extract before you head outside. Apply peppermint cream for a minty, natural gnat repellent. Wear sunglasses and a bandana when walking through infested areas.
