Cockroaches are common household pests that contribute to respiratory asthma and often carry and spread disease. The most common species is the German cockroach.
Female cockroaches produce egg cases that contain about 40 eggs. The egg case is deposited in locations that will provide food and water for the developing immatures.
Young cockroaches begin feeding soon after they hatch from the egg case. They feed on the same materials as the adults, generally foods that contain sugars and starches but they will eat almost anything. After shedding their skin several times to grow larger, they become adults. Adults live for about 6 months. They feed at night and are inactive during the day.
German cockroaches move along edges when they are foraging for food and water at night, the time of day when they tend to be the most active.
