What Is the American Cockroach?
The American cockroach (Periplaneta americana) is the largest common cockroach species found in North Carolina homes, growing up to 2 inches long. These reddish-brown insects have a distinctive yellowish figure-8 pattern on the back of their head and fully developed wings, though they prefer running to flying.
Habitat & Behavior
Often called “palmetto bugs” or “water bugs,” American cockroaches thrive in warm, damp environments. They are commonly found in basements, crawl spaces, sewers, and around drains. In commercial settings, they frequent restaurant kitchens, food processing plants, and grocery stores.
American cockroaches are more than just a nuisance—they carry bacteria including Salmonella and E. coli on their bodies, contaminating food and surfaces. Their shed skins and droppings are known allergens and asthma triggers, particularly in children.
Prevention & Control
These roaches can live up to two years and a single female can produce over 800 offspring in her lifetime. Early signs include droppings that resemble black pepper, a musty odor, and egg cases found in dark, moist areas.
