How long can a German cockroach live as an adult?

The lifespan of an adult German cockroach typically ranges from 6 to 12 months under favorable conditions, with many sources citing around 10 months as an average duration. This longevity allows the cockroach to reproduce several times during its life cycle, compounding infestations when not adequately managed. Factors such as availability of food, water, and shelter can significantly influence their lifespan, but the innate biological potential positions the average adult cockroach's life closer to the 10-month mark. This understanding is essential for pest control professionals, as it underscores the importance of timely intervention measures to disrupt the reproductive cycle and manage populations effectively.
