On average, how long do rats typically live?

Rats, particularly the common species such as the Norway rat and the black rat, typically have a lifespan of about 2 to 3 years in a natural environment. This lifespan can be influenced by various factors including genetics, predation, food availability, and environmental conditions. In captivity, where they are protected from predators and have a steady food supply, some rats can live longer, but the average lifespan remains consistent at around 2 to 3 years.

Understanding this information is crucial for pest control purposes, as it helps in assessing the reproductive rates and population dynamics of these rodents within an environment. Effective pest management strategies often consider the life cycle and average lifespan of pests to implement timely control measures.
