Ben's Wilderness Formula Tick & Insect Repellent offers protection from ticks and insects that may carry West Nile Virus (WNV), Lyme disease, Malaria, Eastern Equine Encephalitis (EEE), and other infectious diseases. Providing up to 8 hours of effective protection, Ben's 30's unique formula is made to evaporate slowly - so repellent stays on longer with little absorption into the skin.
