Yes, there are a few natural ingredients that repel bugs effectively, and using them will keep you safe regardless of how much time you spend outside. Tea tree oil, lavender, lemon eucalyptus oil, and citronella are among the ingredients. These essential oils can never be used in their natural state. Before applying to your skin, you should dilute them as directed. To keep bugs at bay, use some DEET-containing lotion or mist. You can get the same results with eucalyptus or lemon oil. Bear in mind, though, that these sprays typically wear off after a few hours. If you intend to spend a lot of time outside, carry the spray with you and reapply as required.
