Aurora stretches across the High Plains east of Denver at around 5,400 feet, where winters are cold, summers are dry and hail is a regular visitor. That sounds unfriendly to bugs, yet pests are plentiful. Irrigated lawns, mature cottonwoods along the creeks, and a lot of newer housing create pockets of moisture and shelter that insects and rodents are happy to use.
What homeowners deal with in Aurora
The typical list looks different from the humid South. Boxelder bugs cluster on sun-warmed walls in fall. Clover mites bloom on foundations in spring. Miller moths flutter through porch lights in late spring. Pavement ants, odorous house ants and the occasional carpenter ant enter kitchens and bathrooms. House mice and deer mice enter garages as nights cool. Wolf spiders, hobo spiders and black widows hide in woodpiles and window wells. Wasps and yellowjackets are active from late summer into the first frost.
How local conditions shape the problem
Aurora grew fast. Subdivisions around Tallyn's Reach, Saddle Rock and Southlands share open space, drainage channels and prairie grass at their edges, which sends rodents and insects toward houses. Fitzsimons and the Anschutz Medical Campus area contain apartments and rental units where German cockroaches and bed bugs spread easily. Meanwhile, the dry air and big temperature swings drive insects to seek warm, sheltered spots inside walls and attics, especially after the first hard freeze. Parks around Aurora Reservoir and Cherry Creek State Park bring in migrating wildlife and the insects that feed on it.
The seasonal pattern
- Spring: clover mites, ants waking up, and wasps starting nests under eaves.
- Summer: spiders, earwigs in watered garden beds, mosquitoes near ponds.
- Fall: boxelder bugs, mice and cluster flies looking for winter shelter.
- Winter: rodents inside garages and attics, plus indoor cockroaches in heated apartments.
What a visit includes
A technician typically inspects the exterior for gaps at door thresholds, utility lines, window wells and roof vents. Interior checks focus on kitchens, bathrooms, basements and attics. Common work includes a perimeter treatment timed for fall and spring, bait stations for ants, trap placement for mice, and exclusion work with sealant and mesh. Many Aurora households choose a seasonal plan so treatment lines up with the peak migration times.
Advice for Aurora houses
- Caulk gaps around windows, siding and where cables enter the house before fall.
- Keep gravel or bare soil between shrubs and the foundation.
- Clean up grass clippings and leaves near the walls.
- Check window wells for debris that shelter spiders and mice.
- Switch exterior bulbs to yellow or warm-white LEDs, which attract fewer insects.

Why do boxelder bugs swarm my Aurora home each fall?
They gather on warm south and west walls and seek cracks to overwinter. Sealing gaps and exterior treatment in early fall reduce the number that get in.
Are black widows a concern in Colorado?
They live in the state and favor sheltered spots like woodpiles, meter boxes and garages. Wear gloves when moving stored items.
Does the cold winter kill pests?
It kills some outdoors, but many species move into heated buildings to survive, so winter does not end the problem.
Do I need year-round service?
Many homeowners choose seasonal visits rather than monthly ones. Your provider can recommend a schedule based on what you see.
