There are five kinds of cockroaches in Missouri and Kansas. They are German, Brownbanded, American, Oriental, and Pennsylvania Woods. The German cockroach is the most invasive species. The female will carry the egg capsule for about three weeks and she will drop it, one day before the eggs hatch. This egg capsule has 30 to 40 eggs in each capsule. Altogether the female will produce from four to eight capsules in her lifetime. This is why they can reproduce so rapidly. I can treat cockroaches in restaurants, homes and apartments safely and effectively.
