Reproduction Cycle of a Cockroach In three to four months, those baby roaches will develop into fully grown adults. The lifespan of a cockroach is usually one year, and in any female roach's lifetime, she can produce anywhere between 200 to 300 offspring or 6 generations a year.
A single pair of roaches can produce up to 400,000 descendants in a year, under optimal conditions. When you consider that most roaches develop into adults in under 35 days, you realize it doesn't take long for a home to be infested. The only real limiting factor is the availability and quantity of food sources.
Typically, cockroaches stay away following a treatment or service, but sometimes these pests may return with a vengeance! Keep reading to learn more about recuring cockroach infestations and what you can do to prevent these pests from returning.
