Cockroaches are persistent and troublesome pests of homes, restaurants, hospitals, warehouses, offices, and other structures with food handling areas. These insects contaminate food and utensils, destroy fabric and paper products, and impart stain and odor to surfaces they contact.
Unhygienic scavengers in human settlements. Cockroaches are among the most common pests in many homes and other. buildings. At night they search for food in kitchens, food storage places, rubbish. bins, drains and sewers. They are pests because of their ï¬lthy habits and bad smell. Some people may become allergic to cockroaches after frequent exposure. Cock-. roaches can sometimes play a role as carriers of intestinal diseases, such as. diarrhoea, dysentery, typhoid fever and cholera.
