Cockroaches or roaches are insects of the order Blattaria. This name derives from the Latin word for "cockroach", blatta. Cockroaches live in a wide range of environments around the world. Pest species of cockroaches adapt readily to a variety of environments, but prefer warm conditions found within buildings. Many tropical species prefer even warmer environments and do not fare well in the average household. Roaches are not able to survive in moist areas such as bathrooms and are not able to exit such areas.
