There are over 4000 species of cockroaches, but only 4 which are well known as pests. These are the Oriental, Asian, German and American cockroaches which are found across a large percentage of the world. They are considered pests because they may leave an offensive odour, transport microbes that may be dangerous to humans and/or causes allergic reactions to people.
Where do cockroaches come from?
As with all pest species it is difficult to be certain where they have originated from. The names of the cockroaches also lead to confusion as the American cockroach, for example, was probably brought to America by boat from Africa.
The general consensus today is that cockroaches originated from tropical and sub tropical areas of Africa and were transported around the world via transportation such as boats. This trans-location is still happening today and recently the Asian cockroach has been found in the southern United States.
What do cockroaches eat?
Like humans, cockroaches are omnivores. They have a preference for human and pet food, but will eat almost any organic matter. Some pest species have even been known to feed on book bindings, clothing, glue, soap, toothpaste and other household items.
