The cockroach is 1 to 2 centimeters long. It is brown with an oral appliance shaped mill solid opening like pliers (jaws).
Its antennae are long, thin like a thread. Its legs are thin and elongated for walking, running and climbing.
It has three pairs of legs and two pairs of wings. They are laid on each other. The upper pair is hard, tough and not generally adapted for flying.
Cockroaches live in hot places so they can hardly survive in winter. They are found easily in bakeries, restaurants, food factories and hospitals. They are found worldwide except in polar regions.
