Cockroaches

To the untrained eye, all cockroaches may look alike. However, there are actually five species of significance. German, Brown-banded, Oriental, American and Common Wood cockroaches are all unwelcome pests.
The main attractions for a cockroach are food, water and shelter. To them, almost anything is food – 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 are a public health concern because they have been known to carry Salmonella bacteria – the organisms responsible for food poisoning.
Although some people worry that admitting to an infestation of cockroaches indicates poor housekeeping, at times even the most conscientious housekeeper may find it impossible to avoid an infestation.
