Anyone who has spent a summer in Greensboro has had a run-in with a large roach on a patio or in a garage. Warm, humid weather and a climate that rarely freezes hard make the Piedmont a comfortable home for several roach species, and the city's mix of older homes, apartments and food businesses keeps them busy.
Four roaches, four habits
- American cockroach: big and reddish-brown, living in sewers, storm drains, mulch beds and crawlspaces, coming in on warm nights or when it rains heavily.
- Smokybrown cockroach: dark and glossy, living in trees, gutters, attics and wood piles, and flying toward porch lights in summer. It is common throughout the Southeast.
- German cockroach: small and tan, living inside, usually in kitchens and bathrooms. It spreads through shared walls and on carried belongings.
- Oriental cockroach: shiny black and sluggish, favoring cool, damp crawlspaces, drains and basements.
Why Greensboro homes see them
Crawlspaces are the main reason. Their humidity, dark corners and small gaps connecting to the house make them perfect roach habitat. Older homes in Fisher Park, Sunset Hills and Lindley Park often have pipe penetrations and uncovered floor drains that allow roaches to climb up from below. Apartment communities near the colleges and along Wendover Avenue and Battleground Avenue see German roach problems that spread between units. Restaurants and bakeries downtown and at Friendly Center need constant vigilance.
The professional approach
For outdoor roaches, treatment centers on the exterior: the foundation perimeter, crawlspace vents, mulch beds, gutters, and wood piles. Sealing around pipes, repairing door sweeps and trimming vegetation off the house matter as much as any product. For German roaches, the provider uses gel baits, monitors, growth regulators and targeted crack-and-crevice work indoors, with follow-up visits every couple of weeks until activity stops. Professionals will also recommend sanitation improvements and moisture control.
Drainage matters: roaches thrive in crawlspaces with standing water. Fixing leaks and improving ventilation can reduce the population significantly.
Weather plays a role in timing. After a heavy Piedmont thunderstorm, sewer lines and storm drains fill, and American roaches climb out looking for dry ground, often ending up in garages, laundry rooms and bathrooms. A dry spell in late summer can have the same effect, driving them toward moisture indoors. Neither pattern reflects on how clean a home is, and both are handled most effectively by combining an exterior treatment with sealing of the gaps at doors, pipes and vents.
What you can do
- Seal food and pet bowls, and sweep or vacuum crumbs.
- Run water in seldom-used drains to keep traps filled.
- Put weatherstripping on exterior doors and garage doors.
- Clear leaf litter, piled mulch and firewood from the foundation.
- Repair leaking faucets and under-sink plumbing.

Greensboro roach FAQ
Why did a huge roach show up in my clean kitchen?
It probably came from outdoors, drawn by moisture and warmth. Cleanliness doesn't always keep outdoor species away.
Are Southern roaches able to fly?
Some, like the American and smokybrown roach, do fly short distances in hot weather.
Do roaches bite?
Rarely. Their main risk is contamination and allergens.
Can pest control hurt my pets?
Products are used according to their labels. Tell your provider about pets so they can choose placement carefully.
