Colorado pest control: common pests, seasons & local options
From the red rocks of Garden of the Gods to the peaks of the Front Range, Colorado's high, dry climate concentrates pests around irrigated homes. Denver, Colorado Springs, Aurora, and Fort Collins homeowners battle pavement ants, box elder bugs, lawn-damaging voles, and black widow spiders.
Most common pests in Colorado
The four pest problems Colorado homeowners ask about most — and what drives them locally.
Ants
Pavement ants and odorous house ants are Colorado's top indoor invaders along the Front Range.
Box Elder Bugs
Box elder bugs swarm Colorado homes each fall, a signature Front Range nuisance.
Voles
Voles tunnel through Colorado lawns under winter snow, emerging to damage turf in spring.
Spiders
Black widows favor Colorado garages, rock walls, and outbuildings from Denver to the Western Slope.
Pest seasons in Colorado
Colorado's pest calendar follows the altitude: ants in May, wasps and mosquitoes through the short summer, and the September–October invasion of box elder bugs and mice. Snow-covered lawns hide vole damage until spring melt.
