Cockroaches are found in houses and commercial premises associated with the production or handling of food.
They are usually seen at night, spending the day hiding in cracks and crevices around such areas as sinks, drains, cookers, the backs of cupboards and in refrigerator motor compartments.
They are responsible for the spread of a number of human diseases, such as food poisoning, dysentery and similar gastroenteric illnesses. They may also leave a distinctive unpleasant smell or taint on food and other items with which they come into contact.
There are two common species of cockroach in Britain, the Oriental cockroach and the German cockroach.
