West Nile Virus General Information
The city monitors potential mosquito breeding sites city-wide for vector mosquito larvae throughout the entire WNV season (May through September). Areas found to have Culex larvae are treated with Bti (Bacillus thuringiensis israelensis) to control the larvae. In addition to larval monitoring/treatment, the number of adult mosquitoes is monitored by trapping. Treatment usually consists of monitoring and treating with Bti. If a number of factors were to indicate that West Nile Virus is prevalent enough to warrant a public health emergency, than city staff and City Council could decide to conduct targeted spraying for adult mosquito management.
