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.
