Original Tick and Mosquito Repellent- Safe for people of ALL ages including babies (under 6 months apply to clothing), Effective for 1 1/2 - 2 hours. When my daughter was suffering through a Herxheimer Reaction from Lyme Disease Treatment, I developed this spray simply for my family. As a Licensed Esthetician, I have experience in essential oils. I choose oils that are gentle on the central nervous system. The ingredients used are Rose Geranium, Lemongrass and Lemon Eucalyptus, witch hazel, distilled water and the secret ingredient is LOVE, as it was originally made for my family. It is non-greasy and has a Fresh Citrus Aroma.
