Pest Control in Colorado

Colorado pest pressure, metro by metro

Colorado does not have one pest problem — it has one per metro, shaped by local weather:

• arid heat, cold nights and pests that shelter in the same walls people do (Denver)
• arid heat, cold nights and pests that shelter in the same walls people do (Colorado Springs)
• arid heat, cold nights and pests that shelter in the same walls people do (Greeley)
• arid heat, cold nights and pests that shelter in the same walls people do (Fort Collins)

Across the state we cover 17 counties within these metro areas. Browse the metro pages below, or see the Colorado county index for county-level coverage.

Colorado coverage in numbers

Add the state up and coverage looks like this: about 5,290,233 people across 7 metro areas, 82 named communities, 283 ZIP codes and 17 counties — with Denver, the largest metro, carrying roughly 58% of the covered population. Annual average temperatures span from about 35°F around Boulder to 53°F around Pueblo, a spread that moves first-frost dates, termite pressure and tick seasons from one end of Colorado to the other.

The housing stock writes the rest of the story. In Denver, the largest metro, about 42% of homes predate 1980 and the median home was built in 1986 — older framing, older voids, and the pest profile that comes with them. Owner-occupiers make up about 64% of households there, which is why the metro guides speak to homeowners planning inspections and programmes, not one-off visits alone.
