Colorado has 17 counties inside the metro areas this site covers — together about 24,051 square miles of the state, organised around the Denver, Colorado Springs, Greeley, Fort Collins, Boulder, Pueblo metro areas. County pages exist because pest work is local at exactly this scale: licensing is by state, wildlife rules can vary locally, and a provider's actual service routes follow county and metro lines rather than state borders. Find your county below for its pest pressure profile and the metro guides that serve it.
The counties around a metro's core are often where the pressure is most interesting — newer subdivisions built into former farmland and woodland meet established pest populations at the edge, while the urban core deals with the pests of density. Each county page reads its own position in that pattern.
By land, the covered counties run from Weld County (3,985 sq mi), Mesa County (3,329 sq mi), Larimer County (2,596 sq mi) down to Broomfield County at about 33 square miles. The metros anchoring coverage are Denver (metro population 3,092,037; 10 covered counties in Colorado); Colorado Springs (metro population 781,796; 2 covered counties in Colorado); Greeley (metro population 378,426; 1 covered county in Colorado); Fort Collins (metro population 377,292; 1 covered county in Colorado); Boulder (metro population 328,560; 1 covered county in Colorado); Pueblo (metro population 169,277; 1 covered county in Colorado); Grand Junction (metro population 162,845; 1 covered county in Colorado). Those numbers are the frame for everything on the county pages below: area sets how rural a county reads, the metro sets its pest calendar, and the two together set what providers actually deal with there.
The state's pest calendar is anchored by its largest metro, Denver: about 15 inches of precipitation a year, an average temperature near 50°F, roughly 32 days at 90°F or above and 155 days at or below freezing. Every county in this index lives inside that weather pattern, adjusted by its own distance from the metro core.
The pest signature across Colorado runs through mountain, mountain desert country, and the names that recur on county pages statewide are black widow spiders, house mice, wasps and yellowjackets. The largest covered county in the state is Weld County at about 3,985 square miles, served through the Greeley metro. For metro-level guides, see the Colorado state page.
The communities county residents actually name: Denver (about 713,734 residents), Colorado Springs (about 483,099 residents), Aurora (about 390,201 residents), Fort Collins (about 169,705 residents), Lakewood (about 156,309 residents), Thornton (about 142,878 residents) top the list of covered communities here. Each belongs to a county on this page — open that county for the pest picture at community level.
