Are insect repellents with DEET safe for kids?
Q: I want to protect my 4-year-old son from mosquitoes, but I'm worried about slathering him with repellent that has DEET. Will that cause health problems down the line? Dawn A: Insect repellents containing DEET have been tested and approved as safe for kids, but there are some precautions you should take with them. Choose a repellent with no more than 10 percent to 30 percent concentration of DEET (look for N,N-diethyl-meta-toluamide on the label). Use lower concentrations if kids will be outside only for an hour or two. If they're outside longer, consider using a repellent with a higher concentration of DEET. (The higher concentration means that it will last longer.) Generally, repellent with DEET should not be applied more than once a day, and is not recommended for babies younger than 2 months. DEET can be used on exposed skin, as well as clothing, socks and shoes, but should not be used on the face, under clothing, or on the hands of young children. Also: Concentrations higher than 30 percent are not more effective and the chemical (which is absorbed through the skin) can be toxic. Be sure to follow the directions on the label. If you apply insect repellent to exposed skin, do so sparingly. Do not apply repellent to kids' hands - that way, they can't ingest it if they put their hands in their mouth. It also can cause irritation if they touch their eyes. Avoid spraying the repellent anywhere near the mouth, so it can't be ingested. The Centers for Disease Control and Prevention (CDC) says that repellents containing the ingredients picaridin or oil of lemon eucalyptus can protect against mosquitoes as well as repellents containing the chemical DEET. Picaridin is a compound found in many mosquito repellents used in Europe, Australia, Latin America and Asia. Its chemical name, which you might find in the list of "active ingredients" on a product, is KBR 3023. Years of safe use of picaridin in other parts of the world have proven its safety and effectiveness. Oil of lemon eucalyptus is also known as P-menthane diol, or PMD, for short. PMD is a plant-based repellent that gave protection time similar to low concentrations of DEET products. Whatever repellent you choose, check the list of active ingredients to make sure that one of these effective chemicals is on the list.
