How Long Do Cockroaches Live?

A cockroach’s life span varies depending on species. Some species have a life span of less than two weeks, while others live for two years or more. This length of time depends on a number of factors, such as climate and food supply. However, cockroaches can live for a month or even a week without food. As a result, starving them is not an effective pest control method.

Cockroach eggs take approximately a month to hatch, and young cockroaches will undergo a number of other stages before they reach adulthood. They will also molt, which means they will shed their skin. These stages can make it difficult to recognize individual cockroaches.

A typical adult cockroach reproduces once every several months, and each stage may have a lifespan of about 80 days. While this lifespan is somewhat short, female cockroaches may live as long as one year after giving birth. A lack of food or water can also reduce the lifespan of a cockroach.

Cockroaches can survive being decapitated. They have an open circulatory system, and they breathe through holes in their body segments. Since they do not have a mouth, they can survive being submerged in water for up to half an hour. In addition, their heads can keep functioning for several hours, waving their antennae back and forth.
