Using Insect Repellents with DEET

In warm weather, any time you are outdoors, you should wear repellent.

Products with DEET are recommended. DEET is safe and doesn't require a heavy application; a light spray will do. For any repellent, be sure to follow the manufacturer's directions for use.

If using products with DEET, follow the new Health Canada guidelines.

• Adults and children 12 years and older: products containing 30% DEET provide sufficient protection. If you plan to be outdoors for a short period of time, choose a product with a lower concentration. For example:

• Children between 2 to 12 years: the least concentration (10% or less) should be used. Do not apply more than 3 times a day. Do not apply to face and hands. Avoid prolonged use.
• Children 6 months to 2 years: in situations where there is a high risk of complications from insect bites, the use of one application of DEET may be considered. The least concentration (10% or less) of DEET should be used. Everyday use should be avoided.
• Children under 6 months: DEET should not be used.

Note: There has been conflicting information published about the safety of insect repellents containing DEET, particularly when used on children. Health Canada's Pest Management Regulatory Agency re-evaluated the use of DEET in 2002, including a thorough assessment of risks to human health through evaluation of all toxicology and exposure data as well as adverse effects reports from poison control centres. Based on the guidelines established in 2002, and after considering recent studies on DEET released by the Canadian Medical Association and the University of Manitoba, it was determined that no changes to the current guidelines are required.
