The German cockroach is by far the most common and biggest nuisance of all the roaches. They are light brown to tan in color with 2 dark stripes on their head. Immatures are dark brown to black in color with a pale stripe on their backs. Habits:The German cockroach prefers living in warm, humid areas and are usually found in kitchens and bathrooms, but may spread to other areas in a bad case. German roaches can be brought into a structure on grocery sacks and boxes or inside infested refrigerators, microwaves, television sets, etc. Due to their rapid reproduction rate, an infestation can become extremely bad unless treated immediately. They will feed on almost anything with nutritional value such as food, glue, soap, etc. It is possible for the German cockroach to travel outdoors and from house to house in the summer months.
