What is the average lifespan of a house mouse in normal conditions?

The average lifespan of a house mouse under normal conditions is around two years. This duration can be influenced by a variety of factors including environmental conditions, availability of food, and presence of predators. In the wild, many house mice do not live to their full potential lifespan due to these threats, but in a controlled environment, such as a domestic setting, it is common for them to live about one to two years.

While aspects like good nutrition and absence of predators can lead to some mice living slightly longer, two years remains the typical lifespan reported for house mice. This knowledge is vital for understanding house mouse behavior and management strategies in pest control, emphasizing the importance of timely interventions to prevent infestations.
