2018 City of Greeley Mosquito Control Program


Recent rains in Greeley bring much-needed precipitation and remind us mosquito season approaches. Vector Disease Control International will perform work throughout the 2018 season for the City of Greeley’s annual mosquito control program.

Weekly, adult mosquitoes get trapped and monitored at 12 locations throughout the City. Bodies of water in City-owned parks, ponds and open-spaces are treated to eliminate mosquitoes before they hatch, which is the most effective way to reduce the mosquito population. Spraying for adult mosquitoes is done as needed on a weekly basis until fall when temperatures get close to freezing.

Most adult mosquitoes have a lifespan of several weeks, but hot and dry conditions shorten their lives significantly. The mosquito species typically carrying West Nile Virus make up a small percentage of the overall mosquito population, but their numbers typically increase in July and August until cooler weather arrives in September.

Mosquitoes are most active from dusk through dawn and can travel up to several miles away from breeding sites. One way to reduce mosquitoes is to eliminate standing water on or near your property. Keep mosquitoes outside by repairing window screens, soffits, vents and other means of entry. Protect yourself by wearing treated clothing such as long pants and long-sleeved shirts, socks and shoes when outdoors. Use products with an effective repellant, such as DEET, according to their label.

To report mosquito issues or to learn more about reducing their population, call the City’s mosquito contractor at 303-428-5908. For more information about how to protect yourself from mosquitoes, go to
