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.
