Introduction:
Cockroaches before they develop completely go through three stages. The life cycle of the cockroach spans six months to one year to complete. Usually, the female cockroach lays 20-40 eggs.
The mother cockroach carries her eggs in a sac called as ootheca. Most of the cockroaches are oviparous.
It means that the eggs are outside the mother’s body and after six to eight weeks they emerge as nymphs from the case. These nymphs are white in
They feed on the food at home and slowly grow into the adult brown cockroaches. The adult cockroaches live up to 2 years.
While all the cockroaches complete all the three stages of the life cycle, there are few things that differ in the life cycle with different species of the cockroaches.
In this video, we show a life cycle of a cockroach model for school science exhibition. This can be done very easily using materials that are available at home.

Questions and Answers:
- What are the phases in a life cycle of a cockroach?
A. There are three phases of a life cycle of a cockroach, they are egg, nymph and adult.
2. How long does it take for a life cycle of cockroach to complete?
A. The life cycle of a cockroach takes place for six months to one year to complete.
3. Explain the development of a cockroach?
A. The cockroach hatch from the eggs of the female mother cockroach. These at this stage are called as nymphs.
The nymphs feed on food and molt several times shedding their skin before they finally develop into adults. The adult cockroaches live up to 2 years.
Conclusion:
Cockroaches are one the world’s most common species of insects. Cockroaches infestation causes many problems that include spreading diseases and harmful bacteria at home.
It is very important to get rid of cockroaches at home by using safety measures that are relatively simple and easy to follow.
There are many species of cockroaches in the world. They emit a very bad smell if they brood into large numbers.
They are responsible for spreading allergens like skin cases and
This can increase or allergic responses to individuals who are over exposed or are under prolonged exposure to such environment.
