Insect Repellent Use and Safety (CDC)

An Overview

The easiest and best way to avoid WNV is to prevent mosquito bites.

  • Use insect repellent containing DEET on exposed skin AND on clothing when you are outside. (Read and follow product instructions.)
  • Avoid going outside at dusk & dawn when mosquitoes are most active.
  • Wear long sleeve shirts and long pants when you must be outside during hours of the day that mosquitoes are active.
  • Drain standing water around the house (including puddles, gutters, flower pots, tire swings, and garden equipment) to prevent mosquito breeding areas.
  • Repair tears in screens on windows and doors.
