Cockroach Life Cycle



We have all experienced cockroach infestations in our homes, which fall under the category of pests that pose a threat.Cockroaches, also known as roaches, belong to the superorder Dictyoptera and the suborder Blattodea.Cockroaches and mantids belong to the Dictyoptera family of insects;both are known for having leathery wings, long antennae, and oval-shaped, flat bodies.Understanding these insects' past is crucial for better comprehension.One of the oldest insects, cockroaches have fossils that date back 320 million years.

They are despised everywhere they go, despite spending so much time on Earth.Cockroaches are considered to be carriers of diseases, have a bad odor, and attack food items in homes.To better comprehend, let's take a look at a cockroach's life cycle.

A Cockroach's Life Cycle:

The Eggs (Ootheca) – Stage 1 

Ootheca is the egg shell covering that female cockroaches have on their abdomen.In a ootheca sack, the fertilized female cockroach produces approximately fifty eggs.In order to safeguard the eggs until they reach the nymph stage, the cockroaches carry them in ootheca.The number of eggs that an ootheca can carry varies by species.The environment in which these nymphs live determines how these eggs develop into nymphs.

Stage 2: 

The Nymph The cockroach enters the second stage as a tiny nymph.The nymph cockroach goes through several molting and skin-shedding stages.With each molting, it changes into a body that is white.The nymph grows in size over time, and their exoskeleton gets darker and more rigid.The nymph stage takes different amounts of time depending on the species.It also depends on the environment and whether predators are present.The nymphal phase lasts between 11 and 14 months.The nymph enters the adult stage after completing multiple molting stages and developing wings.

The Nymph Cockroach and the Adult Cockroach (Stage 3) 

can be distinguished by their pair of wings.A cockroach adult's lifespan varies from species to species.Some species only live for two months, while others live nearly two years.Cockroaches are omnivorous by nature, consuming anything from paper strips to the food you left over from last night.A mature female cockroach can rear anywhere from 300 to 400 young during her lifetime.


To survive, cockroaches typically prefer a warm, damp, and dark environment.Although both cockroaches and termites are omnivorous, termites only consume wood.
