American Cockroach

Cockroaches are infamous in part because their presence suggests rather sloppy housekeeping. However, it is not true that cockroaches are only found in dirty and poorly-kept buildings. They can be found in any building. 

Cockroaches, such as today’s species (Periplaneta americana) are also suspected disease carriers. They can carry microbes on their body including those that are potentially dangerous to humans and they are linked to allergic reactions in humans.

Their diet includes almost anything organic and that’s one factor that helped them to thrive for over 280 Million years as some fossils suggest. In their natural habitats they are valuable decomposers, which means they break down dead or decaying organisms. 

The American cockroach is often seen outdoors unlike its relatives that are considered households pests, e.g. the German cockroach (Blattella germanica) that is actually from northern Africa. By the way, the American cockroach probably also originated in northern Africa.
