The word cockroach is stemmed from the Spanish cucaracha. The cockroach is recognized by a flat oval body, long hairlike antennae, and a glossy black or brown leathery integument. The head is directed downward, and the mouthparts are directed to the rear instead of forward or downward as is the case of many other insects. The male usually has two pairs of wings, while the female, who in some species, is wingless or has vestigial wings. The female creates eggs in egg cases (labeled oothecae). These are occasionally held protruding from her body or might be adhered in protected parts. After the female generates an egg case, the soft, white nymphs emerge. As their exoskeleton solidifies, it turns brown in shade. The structure and huge size (certain species demonstrate a wing measurement of over 12 cm [4.7 inches]) of cockroaches have become a keen area in the biological laboratory.

The cockroach takes a warm, humid, dark living environment and is generally found in tropical or other mild temperatures. Just a small number of species have become pests. The insect harms more material than it consumes and has a yucky scent. The food of the roach, which should be both plant and animal produce, can be from food, paper, clothing, and books to dead insects, especially bedbugs. Insecticides can be taken in roach removing.

The American cockroach (species Periplaneta americana) is 30 to 50 mm long (up to about 2 inches), reddish brown, and inhabits outdoors or in dark, heated indoor locations (e.g., basements and furnace rooms). In adult life, usually about 1.5 years, the female deposits 50 or more oothecae, each possessing usually 16 eggs that hatch after 45 days. Nymphal life takes from 11 to 14 months. The American cockroach, originally from tropical and subtropical America, possesses well-developed wings. However, most species are not good flyers.

The German cockroach (Blattella germanica), a common pest in the household and sometimes incorrectly referred to as a waterbug, is light brown with two dark stripes on the prothoracic area. The female deposits the ootheca three days after mating and carries it for about 20 days. Because it is tiny (about 12 mm [less than 0.5 inch] long), this cockroach frequently is taken into houses in grocery bags and boxes; it has been taken between nations by ship. Three or more generations can occur yearly. This cockroach, found in abundance around the water pipes of the Croton Aqueduct in New York City, became labeled the Croton bug.

The brown-banded cockroach (Supella supellectilium) resembles the German cockroach but is slightly smaller. The male possesses completely developed wings and is lighter in colour than the female, whose wings are stunted and nonfunctional. Both sexes have two light-coloured bands over the back. The adult life span is around 200 days, and there could be two generations a year. Eggs may be dropped in clothes, wood molding, or cracks in the floor. With the invention of heated buildings this cockroach became more common in cooler climates.

The Oriental cockroach (Blatta orientalis) is thought to be one of the most disgusting of household pests. It is oval, shiny black or dark brown, 25 to 30 mm (1 to 1.2 inches) long, with a life cycle like that of the American cockroach. The male possesses short, fully developed wings, but the female has vestigial wings. This cockroach has been carried in vehicles of commerce from its Asiatic origins to every temperate regions.

Wood roaches are not domestic pests. Parcoblatta pennsylvanica, the common wood cockroach, lives beneath logs and stones in northern latitudes. The male and female are so unlike in appearance that they were first considered separate species. The male, 15 to 25 mm (0.6 to 1 inch) long, possesses wings that go past the abdomen; the female is smaller and possesses much shorter wings. Cryptocercus punctulatus digests wood with the help of particular protozoans in its digestive tract.
