Dealing with a pest problem in Broomfield? You're not alone. mice, voles, ants are among the most common household pests in the Colorado Front Range — and they're active year-round.
Broomfield occupies the narrow corridor between Denver and Boulder, with Broomfield Commons, Carolyn Holmberg Preserve, and several interconnected open space parcels running through the city. These green corridors are effective wildlife highways — deer mice and voles move along them year-round and find their way into adjacent neighborhoods. The high rate of single-family homeownership and newer housing stock means most infestations start in garages and crawl spaces before residents notice.
spring
Ants emerge as soil warms. Wasp queens begin scouting for nest sites. Mice move back outdoors but may still enter structures.
summer
Peak wasp and ant activity. Brown recluse and black widow spiders active. Voles damage lawns and garden beds.
fall
Primary rodent season — mice and voles seek indoor shelter as temperatures drop below 40°F. Boxelder bugs congregate on south-facing walls.
winter
Indoor rodent activity peaks. Overwintering insects shelter in wall voids and attic spaces.
Broomfield is unique in Colorado as a city and county simultaneously — the only jurisdiction in the state that is both. It was carved out of parts of Adams, Boulder, Jefferson, and Weld counties when it gained city-and-county status in 2001.
