Mosquitoes and West Nile Virus

West Nile virus can affect people, horses, certain types of birds, and other animals. However, only nine species out of over fifty mosquito species in Washington State have the potential to transmit the virus and no human cases have been found in King County.

If mosquitoes carrying the West Nile virus are detected, the City of Redmond will coordinate with lead agencies such as Seattle/King County Department of Health, Washington State Department of Health, and the National Center for Disease Control to provide guidance to Redmond residents on control measures that will need to be implemented.

The following links to various King County and the State of Washington websites offer the most current updates and general information on West Nile virus: 

You Can Help Protect Yourself and Your Family

Local and federal health experts recommend the best personal protection is to reduce mosquito habitat, prepare your home and take personal protection measures.

Reducing Mosquito Habitat

Mosquitoes lay their eggs in standing water. The eggs only need a few ounces of water to grow into adults. Take these steps to reduce mosquito habitat.

• Eliminate places where water can stagnate in containers such as buckets, flowerpots and tires.
• Change water at least once a week in birdbaths and wading pools.
• Clean clogged rain gutters, and put mosquito screens on rain barrels.
• Dispose of old tires or cover them so they don't collect water.
