West Nile Virus

What Can I Do to Protect Myself? Fight the Bite

The best way to avoid becoming sick from WNV is by preventing mosquito bites:

  1. Defend - Use an EPA-registered insect repellent with DEET, picaridin, oil of lemon eucalyptus or IR3535 according to label instructions. Repellents keep the mosquitoes from biting you. DEET can be used safely on infants and children 2 months of age and older
  2. Dawn and Dusk - Mosquitoes that carry WNV bite in the early morning and evening. It is important during this time to use repellent and wear clothing that reduces the risk of skin exposure to mosquito bites. Make sure your doors and windows have tight-fitting screens to keep out mosquitoes. Repair or replace screens with tears or holes.
  3. Drain - Mosquitoes lay their eggs on standing water. Eliminate all sources of standing water on your property, including buckets, old car tires and pet bowls. If you have a pond, use mosquito fish (available from Napa County Mosquito Abatement District) or commercially available products to eliminate mosquito larvae.
