In areas of extreme bug density or other extreme conditions use this 100% DEET spray for application to clothing, and mosquito or head nets. Sawyer makes the only Low-Odor 100% DEET on the market. MAXI-DEET protects exposed skin areas against mosquitoes, chiggers, fleas, gnats and ticks. A little goes a long way, use only as needed. You can control dosage by using a smaller amount rather than a lower concentration. Lower concentrations have more alcohol, which increases absorption and causes skin irritation.
