Oriental Roaches

Scientific name: Blatta orientalis Linnaeus
(Blattodea: Blattidae)

Facts: Adult oriental cockroaches are glossy dark brown to black. Females may be nearly 1 1/4 inches long, while males are 1 inch long. The male’s wings cover most of the body, while the female’s shorter wings are reduced to mere lobes. Neither sex can fly.

Nymphs and adults are usually found near decaying organic matter. During warm, humid weather they inhabit lawns, compost piles, flower beds and dumps. However, in periods of drought or with the approach of cold weather, they move in masses into homes and other buildings. In buildings, these cockroaches inhabit high moisture areas such as sewers, drains and dark, damp basements. Their activities are somewhat restricted to the ground or below-ground levels of buildings.
