Cockroaches
The main attractions for a cockroach include food, water and shelter. To them, almost anything is food, including any foodstuff, paper, cloth, plants, and even glue used for binding books. They can be found in every part of the home, but most prefer some kind of damp environment. Since most cockroaches are active at night, many people may be completely unaware of their presence in their home.
Cockroaches may be a public health concern in certain locations such as restaurants or hospitals because they have been known to carry Salmonella bacteria, the organisms responsible for food poisoning.
