When people think of insect pests, cockroaches are what most often come to mind. These six-legged troublemakers breed like rabbits, they carry disease pathogens and allergens, including triggers for asthma, and their presence is creepy and unacceptable to most folks. Spot one in a restaurant, and it’s time to find someplace else to eat, because roaches contaminate food and eating utensils. There are around 4,000 species of cockroaches in the world, 70 of them now active in the United States. The cockroaches’ life cycle follows a pattern of simple or incomplete metamorphosis, which means that they hatch from eggs as nymphs, and then they go through several molts before reaching the adult stage.
