Another scavenger cockroach is the German Cockroach, which enjoys virtually anything for a meal. These nocturnal cockroaches seek out shelter that is close to food, warmth and moisture. The German Cockroach is typically found in apartments, supermarkets, dining establishments and, yes, homes; and heavy infestations are very common.
Measuring roughly 5/8 of an inch, German Cockroaches are light to medium brown and sport two long dark streaks on their thorax. Adults will live up to one year. Females lay one egg capsule each 20-25 days, with up to 48 eggs in each capsule. Nymphs will mature into adults in as little as 36 days.
About 3,500 species of cockroaches exist worldwide, with 55 species found in the United States. (Factoid Source: Steve Jacobs, Sr. Extension Associate, Penn State University, College of Agricultural Sciences)
