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
