Are insect repellents with DEET safe for my child?
Using a product with DEET (diethyltoluamide) is the best way to prevent bites from insects, including ticks. The amount of DEET in a bug spray is listed as a percentage—the higher the percentage of DEET, the longer it will guard against bites. On children six months to two years old, you can use up to 10 percent DEET once a day. This should provide bite protection for up to four hours. Kids older than two can safely use 10 percent DEET up to three times a day, while teens and adults can use products with up to 30 percent. Hold off using DEET products if you’re pregnant and breastfeeding—more research is needed to determine its safety.
