Mosquito Control

Mosquito control for unincorporated areas of Adams County is provided by Vector Disease Control International (VDCI), formerly called Colorado Mosquito Control, with a local office at 7000 Broadway, Suite 108, Denver. VDCI performs mosquito trapping, larvaciding (treating standing water for mosquito larva), adulticiding (spraying for adult mosquitoes), and responds to mosquito complaints.

If you have concerns about mosquitos, please leave a message with location information with the Mosquito Control Hotline at 303.428.5908. Residents can also check VDCI's website.

What can I do to protect myself from West Nile Virus and other mosquito-borne illnesses?

1. Dress in long sleeves and pants when outside, particularly around dawn, dusk, and at night.
2. Wear light-colored, loose-fitting clothes.
3. Use mosquito repellents containing DEET.
4. Eliminate mosquito breeding habitats by draining standing water collected on your property, such as gutters, flowerpots, fountains/birdbaths, garbage cans/lids, outdoor toys, and buckets.
