American cockroaches — often called palmetto bugs or water bugs — are the largest roach species you'll see in Chicago homes. While they're less common than German cockroaches indoors, they thrive in basements, boiler rooms, sewers, and garbage chutes throughout the city, especially in older multi-unit buildings.
What Do American Cockroaches Look Like?
Adults are 1.5–2 inches long, reddish-brown, with a distinctive yellow figure-8 marking behind the head. Both males and females have wings and can fly short distances, which surprises most Chicago residents the first time they see it happen.
Where Do American Cockroaches Hide?
American cockroaches prefer warm, damp areas — Chicago basements, boiler rooms, garbage chutes, floor drains, sewer lines, sump pumps, and crawl spaces. They often enter homes through plumbing, gaps around utility penetrations, and basement windows.
Signs of a American Cockroach Infestation
Look for large dark droppings shaped like rice grains, dark egg cases (oothecae) glued to walls in basements, a strong musty odor, and live roaches near floor drains and basement perimeter. They're most active at night.
Health Risks of American Cockroaches
Like other cockroaches, they spread bacteria including Salmonella across food contact surfaces, trigger asthma and allergies, and contaminate stored food.

Frequently Asked Questions
Are American cockroaches the same as water bugs?
In Chicago 'water bug' is the common nickname for American cockroaches because they're so often found near plumbing and damp basements.
Can American cockroaches fly?
Yes — both males and females have wings and will glide short distances, especially in warm weather.
Why do I only see them in my basement?
American cockroaches prefer warm, humid areas and feed on organic matter near floor drains. They typically stay in basements unless food sources upstairs draw them up.
Are they dangerous to my family?
They don't bite but they're a documented vector for Salmonella, E. coli, and asthma triggers — and they contaminate any food surfaces they cross.
