DEET-Free Mosquito-Repellent Patch.

Since the first human hand swatted in vain at a swarming mosquito, people have been trying to repel insects every time they head outdoors--and for good reason. Mosquitoes, fleas, ticks, and black flies all have bites that can cause painful irritation at best and debilitating or fatal disease at worst. In 2000, the West Nile Virus, an illness transmitted by mosquitoes, killed one person and made 17 others severely ill. The virus is projected to spread beyond the 12 Eastern states where cases have been documented.

Many of the liquids and sprays commonly used to repel mosquitoes contain N,N -diethyl-meta-toluamide, commonly called DEET. DEET affects the central nervous system, and its toxicity poses a risk for both children and adults. Up to 56 percent of topically applied DEET penetrates human skin, and 17 percent is absorbed into the bloodstream. Reactions have included headache, disorientation, agitation, seizure, anaphylaxis, and coma.

Children are at increased risk because they have a higher surface-area-to-body-mass ratio. Frequent reapplication increases the risk. Recently, the American Association of Pediatrics (AAP) issued a warning that DEET solutions of over 10 percent concentration should not be used on children. AAP also recommends that application be limited to exposed areas of skin or clothing--and that as little repellent as possible be used.

Lanco Research LLC is introducing to the United States a natural, DEET-free mosquito-repellent patch called the Skeeter Defense Patch. Each patch contains 60 milligrams of micro-encapsulated citronella oil. Citronella has been used since ancient times and is the most effective natural substance known for preventing insect bites. Just squeeze the little yellow patch to release the lemon scented fragrance, and you are protected for up to six hours. The patch can be attached anywhere-to picnic tables, lawn chairs, clothing, even your skin. It is safe for the entire family, including infants and children.
