Mosquito Species Information

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

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.

In general, mosquitoes in the genus Aedes are mainly nuisance biters, although one of our most common species, Aedes vexans, is known to be a vector of Dog Heartworm. 

Mosquito Trap Data Reports

Vector Disease Control International (VDCI) operates 14 mosquito traps in Windsor. Mosquitoes are trapped for data-based surveillance to determine an appropriate treatment plan for that area. 

Every week during mosquito season, VDCI will count the amount of trapped mosquitoes and determine a treatment plan based on how many adult mosquitoes were caught. Larvicide, the treatment that kills mosquito eggs, is applied to the trap site every week. Trap thresholds of 100 or more mosquitoes will trigger a truck fogging adulticide application, which targets adult mosquitoes around the trap site.

Fight the Bite

This is a list of recommendations from Fight the Bite Colorado. For more prevention tips, disease symptoms, and answers to questions, visit the Fight the Bite website.

  • 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.
