Essential oils that insects avoid: citronella, lemongrass, lemon eucalyptus, peppermint, cedarwood, geranium and lavender — the oils behind homemade bug sprays, candles, diffuser blends and repellent sachets. Pure and undiluted, so a little goes a long way when blended into a carrier oil, a water-and-witch-hazel spray or soy wax.
Recipes and ratios are in our guides: keep bugs out of the home, essential oils for bugs, and the full insect-repelling series. Bulk sizes for makers who sell outdoor products.
