Fort Collins and Larimer County to spray for mosquitoes

Based on high levels of infected Culex mosquitoes trapped last week, the City of Fort Collins and the Larimer County Health Department hope to decrease the risk of human West Nile virus infection by spraying for mosquitoes on the northeastern part of Fort Collins and adjacent Larimer County.

The area encompasses a large area from E. Prospect Road north to E. Douglas Road, between Timberline and Shields.

The City of Fort Collins and the Health Department will be doing adult mosquito control on August 24 and 28, weather permitting. Spraying will occur by fogging trucks on both Wednesday and Sunday and will begin at 8 p.m. and end by 2 a.m. each night.

The city’s contractor, Colorado Mosquito Control, 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 cloth sheet or tarp.

Adult mosquito control has been going on for several weeks in Loveland, Timnath, Windsor, Johnstown and Berthoud, as well as in certain subdivisions within Fort Collins that are sprayed by homeowners associations.
