Develop and live all over the building. Black stripes running length-wise on back. Develop and live all over the building, especially in kitchens and bathrooms. Short wings or traces only. German and brown-banded roaches mature in 2 to 5 months, others in about a year.
Roaches grow slowly when food, temperature, and moisture are unfavorable.
Conditions are usually not ideal for rapid growth in buildings and homes where good sanitation is practiced. The female lays her eggs in a leathery capsule, which she forms at the end of her body. Others carry the capsule a day or two, then glue it to some object in a protected place. About 12 young hatch per capsule after incubating 1 to 3 months. Roaches may enter the house in infested containers or from adjoining buildings.
