Blattella germanica

German-roaches

Biology

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.
