Identification of American Cockroach

1. Adult American cockroaches are reddish-brown to dark brown (except for a tan or light yellow band around the shield behind the head), about 1-1/2 to 2-inches long, and have wings capable of flight. Males and females are about the same size.

2. American cockroaches are anatomically similar to most other cockroach species. Their heads are comprised of the mouth, salivary glands, eyes and antennae. Their bodies are flat and ovoid in shape. They are protected by an exoskeleton that is oily in appearance.

3. The American cockroach (Periplaneta americana) is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary.

4. The American cockroach is the largest of the house-infesting roaches and a major pest in the United States. It’s also commonly known as the water bug, the Bombay canary or the palmetto bug. Despite its name, the American cockroach is not native to North America and some evidence suggested that American cockroaches were introduced via ships from Africa in the early 1600s

5. American cockroaches live primarily outdoors, but it’s not uncommon to find them inside a structure. In the Northern United States, American cockroaches are typically found in sewers and drains. In fact, American cockroaches are the most common cockroach species found in city sewer systems. It’s been reported that more than 5,000 individual American cockroaches were once found in a single sewer manhole. In the Southern United States, American cockroaches are often spotted in shady, humid areas like flowerbeds and underneath mulch piles. During summer months, they can also be found outdoors in yards and alleys.

6. American cockroaches are filthy pests, and their presence in the home can pose a severe health threat. Cockroaches have been reported to spread at least 33 kinds of bacteria, including E. coli and Salmonella, as well as six kinds of parasitic worms and at least seven other kinds of human pathogens. They pick up germs on the spines of their legs and body as they crawl through decaying matter or sewage, and then transfer the germs onto food or cooking surfaces.

7. American cockroaches are especially common in larger commercial buildings such as restaurants, bakeries, grocery stores, food processing plants, hospitals, etc., where they usually infest food storage and food preparation areas, boiler rooms, steam tunnels and basements. These pests can also infest homes by easily passing underneath doors lacking weather stripping or entering through basement windows and garages. Once inside a residence, American cockroaches usually make their way into the kitchen, bathroom, basement or laundry room in search of food and water.

8. The saliva, urine and fecal droppings from American cockroaches contain allergen proteins known to elicit allergic reactions and asthma attacks. As such, cockroaches are a common trigger of year-round allergy and asthma symptoms, especially in children.

9.American cockroaches feed on many kinds of food, but they show a particular fondness for fermenting material. Outdoors, they tend to eat decaying leaves, fungi, algae and small insects. Indoors, they eat crumbs found under appliances, in drains, behind kitchen cabinets and on the floor. They will also eat pet food that is left uncovered.

10. The American cockroach (Periplaneta americana), also colloquially known as the waterbug, but not a true waterbug since it is not aquatic, or misidentified as the palmetto bug (see Florida woods cockroach for the differences), is the largest species of common cockroach, and often considered a pest.
