The American cockroach is one of the largest cockroaches in the Northeast. It is about 40 mm (1.5 inches) long with a reddish-brown body. The centre portion of the pronotal shield is light brown, while the outer edges are yellow. Even though both sexes are winged, their flight is more of a gliding movement from point to point than active flight
The female American cockroach will not retain the egg capsule for more than a day after its formation, instead of dropping the capsule in some suitable site. Under some conditions, it may be glued to a surface. The number of capsules produced by a female will range from 6 to 14, with each capsule containing 14 to 16 eggs. The eggs hatch in 50 to 55 days.
The American cockroach prefers dark, moist sites where it feeds on decaying organic matter. Such sites include basements, kitchens, clothes hampers, drains, bathroom plumbing or sewers. High populations have been known to develop in sewers, from where they infest households or other structures.
