iant hissing cockroaches are usually found in groups. Female hissing cockroaches like to be in a crowd, but males don't like to be around other males. You can tell males apart from females because the males have bushier antennae. A male cockroach has his own territory and if any other males come too close, he chases them away. The male hissing cockroaches have bumps on their head that they use to fight each other with.

males carry their eggs inside their bodies until they hatch. A female usually has 20 to 40 babies at one time. Baby hissing cockroaches look like tiny adults. Because hissing cockroaches have hard shells, the young roaches have to shed their skins so they can grow. A young cockroach will shed its skin six times before it stops growing.
