What is the Average Lifespan of a Mouse?

While many factors can affect their longevity, mice usually live for about 12 to 18 months. The presence of food, shelter, and predators determines how long these tiny rodents survive. Mice living inside a home typically outlive their wild counterparts, thanks to consistent food sources and protection from natural threats. These pests have a surprisingly fast life cycle, hitting sexual maturity at 6 weeks old. In the right conditions—like a warm, cozy home—mice can breed year-round, with females pumping out up to 10 litters annually. This rapid reproduction and short lifespan make mice such challenging household pests.

How Long Do House Mice Live?

House mice have adapted to thrive around humans. Inside a house that provides shelter and plenty of crumbs or stored goods, the average lifespan of a mouse is about two years. As long as the pests have access to food and water, the only real threats to their survival are disease and humans or pets.

How Long Do Mice Live in the Wild?

In the great outdoors, most house mice fall victim to predators. Rats, snakes, and owls are avid mouse hunters. Lack of food or water, illness, and injury also limit colonies in the wild. In this setting, the average lifespan of a mouse is often less than a year.

Professional Rodent Control for Mouse Infestations

Mice can quickly transform a cozy home into a breeding ground for trouble. With a single female capable of producing 80-90 offspring in her lifetime and mice reaching breeding age at just six weeks, infestations can spiral out of control fast. Due to their rapid reproduction and potential health risks, professional pest control becomes critical in managing infestations. Don't hesitate to call an Orkin Pro for comprehensive rodent control at the first sign of rodent activity.
