The German cockroach is the most common household pest. They are usually found in kitchens, and bathrooms, but can be in any portion of a heated structure. A nocturnal insect, German cockroaches remain hidden in dark secluded harborages during the daylight hours. If you see some during the day, it is a sure sign that a tremendous population exists.

Unlike the other common roaches, they are very small---with a body length of only ½ inch. The female produces 4-8 egg capsules in her lifetime. Each capsule contains about 48 eggs. She carries the capsule until the eggs are ready to hatch. This usually takes 28-30 days. Nymphs molt 6-7 times before becoming adults. The cockroach population can grow at least 3-4 generations each year, and can complete the life cycle in as six weeks.
