Mosquito Control

West Nile Virus is in Colorado to stay and citizens are encouraged to take steps to protect themselves. Arapahoe County is working with Tri-County Health, local cities and towns and special districts to control the pesky insects by larviciding mosquito-prone areas. The County’s mosquito control effort is led by our  Animal Control Division, which is using sophisticated GIS technology to map and track mosquito-prone areas for not only Arapahoe County, but also Tri-County Health and our neighboring cities as well.

People who work outdoors should wear long sleeve shirts and pants, and use mosquito-repellent, especially when outdoors during dusk and dawn, the time of day when mosquitoes are most prevalent. When you are around your home, be sure to dump any standing water in buckets, plant containers, birdbaths, etc., weekly. These are areas where mosquitoes breed.

If you have questions about West Nile Virus, contact the Colorado Health Education Line for the Public (CO-HELP) at 1-877-462-2911 between 7 a.m. and 11 p.m. daily. Operators will be available to provide information on virus symptoms and infection in humans and animals.
