How long do mice live?

The life of a mouse is a short one. The tiny rodents that are the source of much anxiety and worry for many property owners only live a short while but can cause a lot of trouble. But how long do mice live? In the wild, mice do not tend to live longer than 1 1/2 year. 

The lifespan of mice does vary depending on the species. Below are a few of lifespan averages for some of the most common mouse species in the wild. 

  • House mouse (Mus musculus) – 9-12 months 
  • Deer mice (Peromyscus maniculatus) – 2-14 months 
  • White-footed mouse (Peromyscus leucopus)- 12-24 months 

Cancer is the most common cause of death in mice although studies have noted other causes, including heat and kidney failure. 

For any mouse control issues that you have around your property then contact your local Rentokil specialist today.

Lifespan of pet mice

Mice that are kept as pets tend to live much longer than wild mice. The average lifespan of a mouse kept in captivity is 2 years. Pet mice have one of the shortest lifespan of all pet rodents. If you are concerned about children getting attached to a pet mouse, you may want to consider another pet that lives longer. 

Mice in laboratories have lived much longer than wild mice with some studies recording normal mice living up to 4 years. Mutated mice bred in captivity have lived beyond four years with the longest life of a mouse being record at just short of 5 years.

Extending mouse lifespan

The lifespan of mice in captivity might be getting longer as Researchers at the Mayo Clinic just published a study that showed they could extend the lifespan of mice by 35% by removing cells that stop dividing with age. The mice in the study experienced delayed tumor formation and improved organ performance. The study suggests that a drug could develop to help humans live longer as well.

A fast life

From their birth to their death, mice live extremely fast lives. Mouse pups will stop nursing on their mother only after a few weeks and set off on their quest for food, things to gnaw and successfully reproduce. At 6 weeks, female mice are sexually mature and capable of having babies. Being very small mammals, mice in the wild have a long list of predators, ranging from birds to coyotes to snakes, which shortens their life expectancy. In areas where predators are not abundant, mice populations can explode resulting in significant damage to their environment.

Why worry about mice?

Just because a single mouse does have a long life it does not mean your infestation will subside after a year. Mice are prolific breeders. A single female mouse can give birth to 25-60 mice in a year. A few mice gaining entrance to your property can quickly turn into a full blown infestation.
