It’s interesting to note that roaches do, in fact, contain microorganisms that help them survive. They have microbes in their bodies that they surprisingly inherited from their parents. These bacteria consume the cockroach, providing it with the vitamins and amino acids it needs to survive.

Cockroaches are thus never genuinely concerned about what they consume. They don’t even need to hunt for foods that are high in nutrients. They are able to eat nearly anything while still getting the nourishment they need to grow.

Additionally, studies on Speckled cockroaches have discovered a connection between body size and lifetime. These results indicate that in this species, body size and aging are strongly correlated, and that bigger size is advantageous for survival.

Pheromones are used by cockroaches to attract females, and males exhibit courtship behaviors such posturing and stridulation. Within three to seven days of mating, cockroach females deposit eggs. The female cockroach produces an egg covering called an ootheca. Using her saliva, the female attaches this egg sac to a surface that is hidden away. There might be several hundred eggs, each of which is home to a cockroach larva. The cockroach eggs will be kept secure by being tucked away.

The eggs hatch after about a month of gestation, during which time the larva within develops. Nymphs are the name given to these larvae. The young cockroaches will go through several more stages, growing larger and molting (losing their skin), until finally becoming the cockroach we are familiar with. Eggs grow into adults over the course of three to four months. Because of their partial metamorphosis, cockroach nymphs resemble adults only to the extent that their wings and genitalia have developed.


The cockroach will grow wings and antennae as it gets older. Additionally, it will be prepared to reproduce and mate. They will continue to reproduce, live out their lives, and give birth to more baby roaches.
