With the 30 percent active DEET formula, this convenient sheet is highly effective against West Nile Virus, Lyme disease, human granulocyctis, ehrlichiosis, encephalitis, malaria, dengue fever and spotted fever. Formula allows the DEET to be released in a more controlled and measured manner, permitting longer lasting performance once obtained only by high concentrations of DEET. Water-based formula is also also nongreasy, nonstaining, low-odor, water-resistant and sweat-resistant. Each towelette is individually wrapped in easy-to-carry foil pack with towelette pouch.
