DEET is short for a chemical (N,N-diethyl-meta-toluamide) that is commonly used as the active ingredient in many products designed to repel (not kill) insects, especially mosquitoes. DEET works by interfering with the ability of insects to “smell” – sensory receptors on the mosquitos antennae become unable to locate scents emitted by humans and animals. When used as directed, products containing DEET can effectively guard you against insect bites. Health concerns can arise if proper directions for use and precautions are not followed. Use only sparingly on intact skin that is exposed (not covered by clothing). Products containing a high concentration (50% or higher) of DEET, overuse or prolonged exposure can result in skin irritation, such as rashes and blisters. Before applying on your kids, make certain the label states that the DEET-containing product is safe for use on children because improper or overuse can result in severe side-effects. Children under the age of 12 should not be permitted to self-apply. Once indoors, thoroughly wash the DEET product off with soap and water.
