The common mouse is a harmful rodent species that has successfully spread all over the globe. It owes this global conquest to its great capacity for adaptation, but above all to its extremely short reproductive cycle.

Learn more about the mouse reproduction rate so that you can have a better idea of the risks you are exposed to if mice get into your home.

Rapid gestation

Female mice have a very short gestation period. When a female becomes pregnant, it only takes her between 19 and 21 days to give birth. Each litter usually consists of five or six mice. However, it is not uncommon to see litters with up to 12 young.

A female can have up to 10 litters per year

The number of litters a common mouse can have in a year also contributes to accelerating this rodent’s reproductive rate. A female can give birth up to ten times in a year.

In addition, she can mate immediately after delivery, which means that there may be only a 25-day delay between two litters of mice. This dizzying cycle continues until the mouse dies. At that point, much time has passed since her little ones started to reproduce in turn!

Mice that are rapidly ready to reproduce

Mice are born without fur, without ears and blind. The mice are breastfed for about 21 days before being weaned. At this stage, they have a protective coat, their ears are fully developed and they are able to see. In short, breastfeeding is over and the young mouse is ready to start chewing your belongings and food to feed itself.

From the age of 6 weeks, the female mouse is sexually mature and ready to start producing its own offspring. This rapid maturation process gives common mice almost unique reproductive abilities among mammals.

Don’t let the mice in!

Living inside an insulated building improves these abilities because mice can reproduce all year round under these conditions. Outdoors, breeding occurs only in spring, summer and fall, with winter months often being too harsh for litters to survive.

Just as the reproduction rate of mice increases if they take refuge in a house, so does their life expectancy. While the average life span of a mouse is only about 12 months outdoors, this number can reach 2 to 3 years when it manages to settle indoors.

In a closed and temperate environment, mice are not exposed to the elements or natural predators. As a result, they have nothing to do but look for food, chew on different materials and objects and continue to reproduce.  All while spreading pathogens that are dangerous to human health.
