Length: Adults can be slightly more than 50 mm (3 inches) long.
Adult American cockroaches are reddish brown or mahogany colored. The area behind their heads is outlined with yellow band
Female American cockroaches make protective cases for their eggs. These cases are capsule-shaped. After forming a capsule, the roach deposits it in a warm, humid area. An average American roach egg capsule contains about 16 eggs.
When the eggs hatch, the tiny nymphs come out of the capsule. As they grow, the immature roaches shed their skins. If there is plenty of food, American cockroaches can develop from egg to adult in as little as 5½ months.
Behavior & Diet
Both male and female American cockroaches can fly. The wings develop when the roaches become adults.
American cockroaches normally live outdoors. They prefer warm, damp areas like flowerbeds, and under mulch. In many parts of the United States people call them “palmetto bugs” because they live on trees. American cockroaches are very common in sewer systems of many American cities.
American cockroaches enter homes to find water or food. They can easily pass under doors if the weather stripping is damaged. Basement windows and garages are also common entryways. When American cockroaches enter homes, they often go to bathrooms, kitchens, laundry rooms and basements.
Outdoors, American cockroaches eat leaves, tiny wood particles, fungi and algae. They also eat small insects. Indoors, American cockroaches forage under appliances, in drains, in kitchen cabinets and on the floor. They eat crumbs, scraps of food and spilled food that they find. They will also eat pet food that is left out overnight.
