Oriental Cockroach Life Cycle

The understanding of the oriental cockroach life cycle leads to a good understanding of its control. The cycle comprises three stages: egg, nymph, and adult. Egg capsules (oothecae) of about 16 eggs each laid by the females.

The oriental cockroach nymph has to have seven to ten molts over a period of six months to a year for it to reach the adult stage. The latter has a lifespan of about six months, during which they are busy multiplying and growing the infestation.
