Aurora's dry high-plains climate is rough on outdoor cockroaches, so those that thrive here are almost all living indoors. That changes the picture compared with Gulf Coast cities: instead of big flying roaches arriving after storms, Aurora's roach problems are largely German cockroaches in kitchens and bathrooms, spread through apartments, restaurants and shared buildings.
Which roaches live in Aurora
German cockroaches are the dominant pest. They are small and tan, with twin stripes behind the head, and they reproduce fast in warm, humid pockets such as behind the dishwasher or under the bathroom sink. Brown-banded roaches are less common but turn up in dry rooms, living rooms and bedrooms, hiding in furniture and electronics. American cockroaches appear occasionally in basements, steam tunnels, sewer access points and large commercial kitchens, and Oriental cockroaches may be found in cool damp areas like crawl spaces and laundry rooms.
How they get in and spread
Most infestations travel. German roaches hitchhike in grocery bags, used appliances, boxes and secondhand furniture, then move through shared plumbing and wall voids. In apartment communities around Havana Street and Colfax Avenue, in student and staff housing near Anschutz, and in older rental stock, one unit's problem is often a building problem. Restaurants and food courts in busy retail centers like Southlands add pressure. Heated buildings keep roaches active through the coldest months, when you might otherwise assume they would die back.
Signs of roaches in the home
- Seeing roaches when you flip on the kitchen light at night.
- Small black droppings or smears in cabinet corners and drawers.
- Oily, musty odor that gets stronger in larger infestations.
- Oval egg cases attached to cardboard or stuck behind appliances.
- Roaches emerging from the dishwasher or stove during use.
How a professional tackles them
Treatment starts with inspection using flashlights and sticky monitors to find the hot spots. Gel baits and insect growth regulators are the backbone of German roach control, since baits can be carried back to nests. Dust treatments in wall voids and sealing of plumbing gaps reduce routes between units. In multi-unit buildings, simultaneous treatment is best. Providers also coach residents on sanitation, moisture and clutter, all of which determine whether the treatment lasts.
Steps for Aurora residents
- Wipe appliances and counters nightly and empty trash daily.
- Repair leaking faucets, and dry sinks before bed.
- Do not bring in cardboard boxes from grocery stores or used items without inspecting them.
- Seal gaps where pipes pass through cabinet backs.
- Report problems to property managers right away so the whole building can be handled.
Restaurants, shared kitchens and storage
Roaches move easily between a business and the homes above or beside it. If you live over or next to a restaurant or in a building with a shared laundry and trash room, ask management when the common areas were last treated. Sticky monitor traps placed under the sink and behind the fridge for a few nights tell a technician which species is present and how heavy the infestation is, which makes the first visit far more productive.

Can roaches survive Colorado winters?
Not outdoors for long, but heated homes and buildings keep indoor species active all winter.
Why do I still see roaches after spraying?
Sprays kill what they touch and can scatter the rest. Baits that the colony carries home are usually more effective.
Is cockroach control different in an apartment?
Yes, because neighboring units can reinfest yours. Whole-building coordination makes treatments last.
Are cockroaches a health hazard?
They can worsen asthma and allergies and contaminate food surfaces, so treating them is worthwhile.
