The American cockroach (Periplaneta americana) is a large species of cockroach, winged, and growing to a length of 1" to 1½" (2.5 cm to 4 cm). It is very common in the southern United States, and in tropical climates, and can be found in many locations throughout the world, due to its travels via shipping and commerce between locations. In the southern U.S., it is often called a Palmetto Bug or a Waterbug. Sightings have been reported in the northeast U.S., such as in New York City, and in southeast Canada, such as in Montreal, where it is mostly found near human habitations due to its lack of cold tolerance. The American cockroach can also be found near various ports throughout the world. They are the largest species of common cockroach.
The insect is believed to have originated in Africa, but had become established in the southern U.S. by the time that it was given its name.
The insect can travel quickly, often darting out of sight when someone enters a room, and can fit into small cracks and under doors despite its fairly large size. It is known to be very mobile, and it also has wings which allow it to be quite a capable flier.
The insect is often considered a pest since it invades living quarters for sanctuary and food.
Characteristics
American cockroach adults are 1 and 1/2 inches long (38mm). They are reddish brown and have a yellowish margin on the body region behind the head. Immature cockroaches resemble adults except that they are wingless.
Habitat
American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures around 84 degrees Fahrenheit and do not tolerate cold temperatures. In residential areas, these cockroaches live in basements and sewers, and may move outdoors into yards during warm weather. These cockroaches are common in basements, crawl spaces, cracks and crevices of porches, foundations, and walkways adjacent to buildings. They feed on a wide variety of plant and animal material.
