Roaches are omnivorous and will eat virtually anything people will and many things we won't. Most cockroaches thrive in warm, damp environments such as sewers, basements, crawl spaces, and boiler rooms. In southern states, they will also be found living and breeding outdoors. The American roach is a strong flier and both sexes have fully developed wings. The female roach can produce 6-14 egg capsules in one mating season. These capsules contain from 10 to 16 eggs each. Incubation for the eggs varies from 38 to 49 days, after which the young nymphs hatch. Cockroaches are known carriers of serious diseases, such as, salmonella, dysentery, gastroenteritis and other stomach complaint organisms. They adulterate food and spread pathogenic organisms with their feces and defensive secretions. Cockroaches must molt regularly throughout their life-cycle. The discarded skin becomes airborne and can cause severe asthmatic reactions, particularly to children, the elderly and people with bronchial ailments. Cockroach pests and their eggs are spread throughout the community in food and other packaging. Although sanitation and hygiene are important deterrents, even the cleanest homes become infested with cockroaches due to minute deposits of grease, sugar and other food deposits in difficult to get at places, such as, in drains, behind refrigerators and dishwashers, inside cracks and crevices in kitchen cupboards.
