Tips for proper protection when using mosquito repellents containing DEET
West Nile Virus is an illness spread by mosquito bites. Preventing mosquito bites can prevent getting West Nile Virus. Insect repellent products containing DEET (N, N-diethyl-m-toluamide) can reduce the risk of mosquito bites, but must be used with caution. Products containing DEET have been occasionally associated with health problems among people who have used it. The reported problems include: skin reactions such as rash, swelling and itching; eye irritation (burning, itchy and watery eyes); and less often, slurred speech, confusion and seizures.
Below are recommended precautions to take when using mosquito repellents containing DEET for adults and children.
Recommendations for use by adults:
Products with 10-35 percent DEET will provide adequate protection under most conditions. Be sure to read the product label and use according to the label directions.
Use DEET sparingly and apply only on exposed skin.
Do not apply to skin under clothing, or to skin that is damaged by sunburn, cuts, or other conditions such as psoriasis.
Wash treated skin and clothing after returning indoors.
Recommendations for use with children:
- For children under 2 years of age, do not use repellent. Use mosquito netting or additional clothing to protect infants.
- Repellents used on children 2-12 years of age should contain no more than 10 percent DEET, according to the American Academy of Pediatrics.
- Do not apply DEET directly to children. Apply to your own hands and then put it on the child. Avoid applying on the child's lips, hands and eyes.
- Do not allow children to apply DEET themselves.
- Wash treated skin and clothing after returning indoors.
- Store all repellents out of the reach of children.
- If you believe you or a child is having a reaction to a repellent containing DEET, wash the treated area immediately and contact your health care provider or the Poison Center (1-800-222-1222).
