The male German cockroach has a more slender body than the female. Both sexes tend to be light brown with two dark streaks that run down their bodies.
German cockroaches grow to be about ½ inch in length.
German cockroaches are found throughout the United States. They only live for about 100 days but breed continuously throughout their lifecycle. They prefer starchy, sugary foods or grease and meat but may settle for soap, glue, or toothpaste if food is scarce. They have even been known to chew on the wings or legs of other German cockroaches when other food sources are not available.
German cockroaches tend to live exclusively near humans, especially in cold climates. Some studies have even shown that German cockroaches cannot survive in buildings without a central heating system in northern locations. They have a particular propensity to congregate in restaurants, food processing plants, motels, and nursing homes.
