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.
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 baby cockroaches shed their skins. If there is plenty of food, American cockroaches can develop from egg to adult in as little as 5½ months.
The American cockroach is also commonly known as the water bug, flying water bug or palmetto bug. These large cockroaches can grow to exceed 50 cm in length. Although the American cockroach is a major pest in the United States, they are native to the tropical climates of Africa. Some evidence has suggested that the American cockroach was brought to North America aboard ships.They are a peridomestic species and live primarily outdoors. In southern states, they are common in shady, humid areas like flowerbeds and around trees. In northern areas, they are usually found in sewers and drains. Climate changes or food shortage can cause them to move indoors.
When they move indoors, American cockroaches prefer to live in moist, humid environments. They can also survive in dry areas with sufficient food and water sources. These insects favor temperatures between 70 and 80 degrees Fahrenheit. When an American cockroach population infests a human home, the insects are drawn to food storage and preparation areas, as well as moist locations. In industrial settings such as restaurants and bakeries, they can be found in boiler rooms and steam tunnels. In residential and commercial buildings, the American cockroach typically infests basements and landscaping.
American cockroaches are moderate flyers. They also gather together in open spaces, while other domestic cockroaches tend to hide in cracks and crevices. They do enjoy sweet foods, but prefer decaying material.
