West Nile Virus
What the City is Doing
Public Health – Seattle and King County leads the response to West Nile virus in Seattle. The City of Seattle supports Public Health’s efforts by:
- • helping to educate people about reducing their risks; and
- • reducing mosquito breeding on City properties.
How the City Reduces Mosquito Breeding
Since mosquitoes only need a small amount of water to breed, the City takes steps to reduce standing water on City properties. The City has a West Nile Virus Response Plan (PDF) and an Integrated Pest Management Plan (IPM) (PDF )that focus more on habitat reduction rather than the use of pesticides to control mosquito breeding. Occasionally, the City uses larvicides to kill the immature stages of mosquitoes before they become flying adult insects. The City favors larvicides that are biological and are least toxic to other insects and animals and has evaluated several products to determine which would be most appropriate for City use.
