Like their German counterparts, Oriental cockroaches eat anything but particularly enjoy sewage, garbage, and decaying organic matter. They often creep into homes through sewer pipes and thrive in damp, warm areas near the ground. On average, females produce eight egg capsules containing 16 eggs each. The eggs mature over the year to become inch-long, dark brown adults who can live for up to six months.
Oriental and German cockroaches are dwarfed by the American cockroach, a reddish-brown pest that can grow more than two inches. The winged pests find their way into homes through cracks under doors, basement windows, and garages, then they make their way to laundry rooms, bathrooms, basements, and kitchens. Spilled food, scraps, crumbs, leaves, fungi and even left out pet food serve as meals for the voracious scavengers. Females reproduce quickly, and the cockroaches can reach maturity in as little as five months.
