Cockroaches have been around for millions of years, evolving into some of the most adaptable pests on Earth. There are approximately 4,000 living species of cockroaches in the world. About 70 of these species are found in the United States.
Cockroaches are commonly found in buildings and homes because they prefer warm environments close to food and water. Unfortunately, cockroaches can cause allergies and trigger asthma attacks, especially in children. They can also spread nearly 33 different kinds of bacteria.
The American cockroach is the largest cockroach found in houses. Despite its name, the American cockroach is not native to North America, but was likely introduced via ships from Africa in the 1600s.
Females can hatch up to 150 offspring per year. Cockroaches don’t get their wings until the become adults.
Brown banded cockroaches get their name from the two light bands they have across their dark brownish bodies. The male’s wings are larger than the female’s wings.
Brownbanded cockroaches often hide their eggs in or under furniture. They usually live 5-6 ½ months.
German cockroaches can be found all over the world. They are the most common cockroach in the United States. Each German cockroach can live about 100-200 days.
Oriental Cockroaches probably get their names from trade ships but they are actually from Africa. They are large and very dark compared to other cockroaches. They usually travel through sewer pipes and drains. They prefer dirty places and cooler temperatures than other cockroaches. An Oriental cockroach creates a strong smell and is considered one of the dirtiest of all the cockroaches.

Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests.

The cockroaches are an ancient group, dating back at least as far as the Carboniferousperiod, some 320 million years ago. Those early ancestors however lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of aphids and other true bugs; they have chewing mouthparts and are likely among the most primitive of living neopteraninsects. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropicalheat. Tropical cockroaches are often much bigger than temperate species, and, contrary to popular belief, extinct cockroach relativesand 'roachoids' such as the Carboniferous Archimylacris and the PermianApthoroblattina were not as large as the biggest modern species.
Some species, such as the gregarious German cockroach, have an elaborate social structure involving common shelter, social dependence, information transfer and kin recognition. Cockroaches have appeared in human culture since classical antiquity. They are popularly depicted as dirty pests, though the great majority of species are inoffensive and live in a wide range of habitats around the world.
