Unscented Cutter Insect Repellent repels annoying biting insects for hours. The 10 percent DEET formula repels mosquitoes, including those that may transmit the Zika, West Nile, Dengue and Chikungunya viruses. This unscented aerosol repellent also wards off other annoying insects, such as ticks, biting flies, gnats, no-see-ums, chiggers and fleas. For outdoor use only. To apply, hold the can 6 to 8 inches from skin and clothing. Use just enough repellent to cover exposed skin and/or clothing. For maximum protection on skin, spread with your hand after application. Don't spray directly on your face - spray on your hands first, then apply sparingly to your face. After you return indoors, wash treated skin with soap and water. Will not damage nylon, cotton or wool - may damage some synthetic fabrics, plastics, watch crystals, leather and painted or varnished surfaces.
