Reduce the Risk of West Nile Virus
Prevention for You and Your Family
The best ways to reduce the risk of infection are:
- Reduce standing water where mosquitoes like to breed
- Avoid infested areas
- Wear long sleeved shirts, long pants, hats, socks and shoes.
- Repair damaged doors and window screens.
- Use an insect repellent that contains DEET (except for babies under 6 months)
Use Insect Repellent Properly
Insect repellents contain DEET, which can be harmful to children.
Read the repellent's instructions carefully and follow these guidelines for your children:
- Under 6 months: Do not use DEET
- 6 months to 2 years: Apply sparingly.
Only when in high-risk areas. Use a spray with 10% DEET or less.
- 2 to 12 years: Use a spray with 10% DEET or less. Do not apply more than three times per day.
- Older than 12 years
30% DEET provides 6 hours of protection
15% DEET provides5 hours of protection
10% DEET provides 3 hours of protection
5% DEET provides 2 hours of protection
