Dealing with a pest problem in Centennial? 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.
Centennial's 2000s-era subdivisions border Cherry Creek State Park and open grassland corridors to the south and east — prime habitat for deer mice and voles that push into garages and crawl spaces as temperatures drop in fall. HOA-maintained landscaping and drip irrigation keep soil moisture elevated year-round, which sustains rodent populations close to structures.
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.
Centennial was incorporated in 2001, making it one of the newest cities in Colorado. It ranks among the largest cities in the state by population despite having no downtown core — it's an entirely residential and commercial suburb built around the I-25/C-470 interchange.
