Based on high levels of West Nile virus infected Culex mosquitoes trapped last week, the City of Fort Collins will spray for mosquitoes in southeast Fort Collins.

Spraying will occur by fogging trucks on both Sunday, Sept. 11 and Wednesday, Sept. 14, weather permitting; it will begin at approximately 8 p.m. each night and end by approximately 2 a.m. the following morning.

Spraying will take place in the area generally bounded by:

  • College Avenue, Harmony Road, I-25, Fossil Creek Reservoir and Trilby Road

Please see the detailed map of the spray area at www.fcgov.com/westnile and attached. The entire spray area will be treated on both nights.

The City’s contractor, Vector Disease Control International (VDCI), will use a permethrin-based product to be applied in a fine mist. To minimize pesticide exposure, residents should stay indoors and keep doors and windows closed for 30 to 60 minutes after spraying. It’s recommended that residents bring pets indoors as well. Residents can further minimize pesticide exposure by covering organic gardens, ponds, and water features with a sheet or tarp. Fogging trucks are equipped with GPS tracking; to follow the trucks’ progress, visit www.fcgov.com/westnile.

The decision to spray for mosquitos follows the recommendation by the Larimer County Department of Health and Environment, in accordance with the City’s West Nile Virus Management Policy.
