The roaches’ ability to survive surpasses all other creatures on earth, their history reaching back to 350 million years ago. Cockroaches are born scavengers. They are found near hot water pipes, kitchen sinks, behind stoves and refrigerators, under kitchen and dining room tables, and in any cracks or crevices big enough for them to hide. Roaches pilfer food, leaving behind their secretions, and contaminating dishes, utensils, packaging, clothing, and stored items. Roaches are a huge source of embarrassment and cause many to express health related concerns. Studies show that roaches are capable of obtaining, harboring, and transferring pathogenic agents to the environment or food of humans. They have also been known to carry virus, fungi and parasitic worms. Roaches have most commonly been implicated as carriers of Salmonella, a cause of food poisoning. There has also been a strong relationship between roaches and the transference of infectious hepatitis. The secretions of roaches have serious effects on allergies, cause dermatitis and conjunctival edema. Cockroach control is considered as a component of disease management.
