How Do Cockroaches Make Sounds?
Cockroaches use a special way to make sounds. They rub parts of their bodies together. This is called stridulation. Many insects use stridulation to make noises. For cockroaches, it is a way to communicate.
The rubbing happens between a rough part and a scraper on their body. When they move these parts quickly, it creates a sound. It is like when you rub your hands together fast.
