This publication documents the conclusions of the Pest Management Regulatory Agency's re-evaluation of personal insect repellents containing DEET. The following is a brief summary of how the re-evaluation decisions apply to the safe use of DEET as an insect repellent for adults and children.
Children under 6 months of age
Children aged 6 months to 2 years
Children between 2-12 years of age
Adults and Individuals 12 Years of Age or Older:
Products containing DEET at concentrations above 30% will no longer be acceptable for registration, based on a human health risk assessment that considered daily application of DEET over a prolonged period of time. Studies show that products with lower concentrations of DEET are as effective as the high concentration products, but they remain so for shorter periods of time. Products containing no more than a 30% concentration of DEET will provide adults with sufficient protection. (New advice)
