Dealing with a pest problem in Highlands Ranch? 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.
Highlands Ranch borders 8,200 acres of open space to the south and west — the Backcountry Wilderness Area brings deer mice and voles directly to the edge of the subdivision. New construction phases continue pushing into grassland, displacing field rodents that find their way into garages and crawl spaces. HOA standards here mean most homeowners call a pro rather than DIY.
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.
Highlands Ranch is an unincorporated master-planned community governed by the Highlands Ranch Community Association — one of the largest HOAs in the United States, with over 100,000 residents and four recreation centers.
