Colorado Mosquito Control (CMC)

Mosquito Trap Data Reports

The CMC Surveillance Laboratory operates ten mosquito traps in Windsor, which are placed weekly throughout the city. Weather permitting, the traps are set on Wednesday afternoons and retrieved on Thursday mornings throughout the season, 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.

Mosquito Species Information
Of the approximately 50 species of mosquitoes recorded in Colorado, a dozen have been found in Windsor.

In general, mosquitoes in the genus Aedes (shown in blue on the pie diagrams - in the Trap Data Reports above) 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 (shown in red on the pie diagrams - in the Trap Data Reports above) 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.

  • DRAIN standing water around your house weekly since that is where mosquitoes lay eggs, including tires, cans, flowerpots, 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.
