Do cockroaches have a lifespan of just a few weeks?

There is a common misconception that cockroaches have a very short lifespan of just a few weeks. While it is true that some species of cockroaches have shorter lifespans, the lifespan of a cockroach can vary greatly depending on the species and environment.

The German cockroach, one of the most common species found in homes, has a lifespan of about 100-200 days, which is around three to six months. American cockroaches, on the other hand, can live up to two years.

Factors that affect the lifespan of cockroaches include food availability, temperature, humidity, and access to shelter. In general, cockroaches that have access to plenty of food, water, and shelter will live longer than those that do not.

It's worth noting that while cockroaches may have longer lifespans than commonly believed, they are still considered pests and can pose health risks. Cockroaches can carry bacteria and pathogens that can cause illness in humans, so it's important to take steps to prevent and control infestations.
