What is the typical lifespan of a firebrat under ideal conditions?

The typical lifespan of a firebrat under ideal conditions is four to five years. Firebrats, which are closely related to silverfish, thrive in warm and humid environments, making ideal conditions critical for their development and longevity. Their life cycle includes several nymphal stages before reaching maturity, and given the right environmental factors such as a consistent food source and suitable temperatures, they can live for several years. This extended lifespan allows them to reproduce multiple times during their lifetime, contributing to their resilience and presence in environments where they are commonly found. Other options reflect shorter lifespan estimates, which do not account for the ideal conditions that enable firebrats to maximize their longevity.
