The hardness is strengthened, the toughness is weakened, and there are small insect holes inside, so it causes a subtle cracking sound in the wood.

Cockroaches do not have vocal organs and cannot call. Like crickets and gnats, the sound of cockroaches and many insects comes from their legs and bodies rubbing against each other.

In different situations, cockroaches can make different sounds: they hiss when they detect the enemy; Otherwise, it's noisy. And when courting, cockroaches will also spew gas from some holes in their stomachs and make sounds.

In addition, cockroaches rub against the ground when they walk, producing sounds; When the foot is stroked, it will make a sound with the ground and paper that it touches; The wings also make sounds when they vibrate.
