Yes! Organic Peppermint oil can be used as a chemical-free insect repellent against ants, spiders, mosquitoes, and other bugs. Try mixing 10 drops of organic Peppermint oil with 4 oz. distilled water, then spritz along windowsills, countertops, and other surfaces to deter insects. You can also diffuse this essential oil or add it to DIY bug-away candles to keep pesky insects away from your outdoor spaces.
