Yes, this product may be used on children in accordance with the product’s directions for use. The CDC states: “No definitive studies have been published about what concentration of DEET is safe for children. No serious illness has been reported from use of DEET according the manufacturer’s recommendations. DEET formulations as high as 50% are recommended for both adults and children less than 2 months of age. Lower concentrations are not as long lasting, offering short-term protection only and necessitating more frequent reapplication.” (www.cdc.gov)We recommend Sawyer Controlled Release Insect Repellent Lotion for children.
