What is the scientific name of the German cockroach?

The scientific name of the German cockroach is Blattella germanica. It is a small, cosmopolitan household pest recognized by the two dark, roughly parallel stripes on its pronotum, the shield-like structure behind the head.

Despite its common name, modern evidence points to South or Southeast Asia as the species’ origin rather than Germany. Human commerce and transport helped it spread worldwide, while warm buildings provide the sheltered conditions it needs. It is now found on every continent except Antarctica.

German cockroaches have wings but generally do not fly well; they may glide when disturbed. They are omnivorous scavengers attracted to starches, sugars, fats, and meat, and can exploit tiny food and water sources indoors. They are sometimes confused with the closely related Asian cockroach, which looks very similar, but the two differ in behavior and habitat preferences.
