The Town of Windsor Mosquito Management Program is coordinated through the Public Works Department in cooperation with Vector Disease Control International (VDCI). VDCI operates 10 mosquito traps in Windsor, which are placed weekly throughout the city during warm weather months.
Weather permitting, traps are set on Wednesday nights, giving a good indication of the relative number of mosquitoes in an area, as well as what species are occurring there. Trap thresholds of 100 or more mosquitoes will trigger a truck fogging application in the area of town around the trap site. This system provides data-based decisions for mosquito spray areas.
Of the approximately 50 species of mosquitoes recorded in Colorado, a dozen have been found in Windsor. In general, mosquitoes in the genus are mainly nuisance biters, although one of our most common species, Aedes vexans, is known to be a vector of Dog Heartworm.
Species in the genus Culex are the main vectors of the West Nile Virus, as well as Western Equine Encephalitis and St. Louis Encephalitis. In Colorado, our main West Nile Virus vector is Culex tarsalis.

Fight the Bite: Tips for Avoiding West Nile Virus
West Nile Virus is a serious health threat that can appear during the summer months in Windsor, due to the Culex mosquito. Here are some recommendations to protect yourself from the West Nile Virus provided by Fight the Bite Colorado:
- DRAIN standing water around your house weekly since that is where mosquitoes lay eggs, including tires, cans, flower pots, clogged rain gutters, rain barrels, toys and puddles.
- DUSK AND DAWN are when mosquitoes that carry the virus are most active, so limit outdoor activities or take precautions to prevent mosquito bites.
- DEET is an effective ingredient to look for in insect repellents. Always follow label instructions carefully.
- DRESS in long sleeves and pants during dawn and dusk or in areas where mosquitoes are active.
