What does it mean when a cockroach hisses?
Hissing cockroach behavior and facts 1 Hissing cockroaches live in large colonies. 2 They hiss when threatened by a predator, to sound an alarm for other roaches in their colony or during male cockroach fights. Small holes called spiracles on their backs are used for breathing. If they force air out of the spiracle quickly, it makes the hissing sound. This audible use of the respiratory system is more common in vertebrates (as when humans emit a heavy, noisy sigh). Most insects that make noise do so by rubbing body parts together or by vibrating membranes. 3 They're most active at night. 4 Males sport large horns, which they use in aggressive encounters like the battles between horned or antlered mammals. Rivals ram each other with their horns or abdomens and hiss as they fight. Winners hiss more than losers, so the sounds may help determine a roach hierarchy. 5 They're an important link in the food chain, breaking down forest debris and providing food for larger animals.

Madagascar cockroaches can be kept as exotic pets. They require a small living area with an area for them to hide because they dislike light sources. The cockroaches prefer warmth and they cannot function in cold weather. Due to their propensity to climb, the living area must be tested to see if they can climb it as they do in their natural environment. Fish tanks with screens work best but it is also wise to coat the top few inches with petroleum jelly to keep them from getting out of the habitat that they are kept in.
