Adults are about 1/2-5/8 inches in length. They are light brown to tan except for 2 dark longitudinal stripes on the pronotal shield. Females are darker than the males, her abdomen is also broader than his. They rarely do fly. German cockroaches are found throughout structures but show a preference for warm and humid areas. They are usually found in kitchens and secondarily in bathrooms. Infestations often occur in rooms where people eat and drink (i.e. the den, bedroom, kitchen, etc.). Any crack located near a source of food and/or water is prime feeding grounds, and they spend about 75% of their time in such a place. First instar nymphs require a crack of about 1/32 of an inch, whereas adults require a crack of about 3/16 inches in width.
