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 filthy habits and bad smell. Some people may become allergic to cockroaches after frequent exposure. Cockroaches can sometimes play a role as carriers of intestinal diseases, such as diarrhoea, dysentery, typhoid fever and cholera.
The American cockroach is the largest cockroach found in houses. Despite its name, the American cockroach is not native to North America, but was likely introduced via ships from Africa in the 1600s.Females can hatch up to 150 offspring per year. Cockroaches don’t get their wings until they become adults.
