DEET “The current American Academy of Pediatrics and Center for Disease Control recommendation for children older than 2 months of age is to use 10% to 30% DEET. DEET should not be used on children younger than 2 months of age.” (2016 Summer Safety Tips, AAP). Some animal studies showed increased risk of seizure and neurological damage so many people are concerned about using DEET. The Environmental Working Group (EWG) says: “After reviewing the evidence, EWG has concluded that DEET is generally safer than many people assume and remains a viable option for people in areas infested with disease-carrying pests.”
