This quick maturation process gives mice immense breeding capabilities. Living indoors enhances these capabilities, since they can then breed all year long. Outdoors, breeding only occurs during spring, summer and fall. The winter months are too harsh for successful breeding. And just like the breeding output increases if a mouse takes refuge in your home, so does the length of their life. While the average mouse lifespan is only about 12 months outdoors, indoors, this number can climb to 2 to 3 years.
That leaves them with nothing to do but eat through your valuables, spread disease to your family and breed future generations to carry on the scourge. She can mate immediately after giving birth, meaning mice can birth a second litter in as little as 25 days after the first. This quick maturation process gives mice immense breeding capabilities.
Living indoors enhances these capabilities, since they can then breed all year long. Outdoors, breeding only occurs during spring, summer and fall. The winter months are too harsh for successful breeding. This cycle continues until the mouse dies. If you think you can avoid dealing with that mouse in your home by simply waiting for it to die, think again. The life cycle of a mouse makes it easy to see why these rodents are such common pests.
Not only can mice have multiple babies at once , they also can have multiple litters each year. Female house mice can have up to six pups every three weeks and can give birth to a second liter as early as 25 days after the first. In one year, they can give birth to approximately 35 babies.
On average humans will only have one baby per year and a total of two in their lifetime, so compared to people, that is a lot of mice! Mice are born without fur, ears, and the ability to see.
The issue is not with the breeding itself but how quickly mice mature. Mice have no boundaries when it comes to mating and will easily inter-breed, causing the issue to spiral out of control. The mice in your home may have been around for generations, especially when you have purchased a home in a historic neighborhood. Generations after generations might have been living and dying between the four walls of your home. Baby mice stay with their mothers for a minimum of 3 weeks. They are virtually deaf and blind when they come into this world.
The average life span of a mouse in nature is usually under a year and this is due to several factors. The mouse is a well-sought after prey that is liked by every animal you can imagine. From dogs to snakes, despite all these hurdles, the mouse can find a safe haven in human habitats. You will be surprised to find out that the lifespan of a mouse living inside of a human home is tripled, and this is the reason why it is so hard to move out of the home because there is almost nothing to counter the benefits of a warm home has to offer with plenty of food.
Professional pest technicians are therefore needed to make sure that they will no longer be a bother and a menace to your normal way of life. A mouse will nurse her babies for approximately 3 weeks. However, she is capable of breeding again almost immediately after she gives birth. In other words, a female mouse can have another litter of babies approximately 25 days after giving birth to the previous litter.
In fact, her female offspring have likely already given birth to several babies of their own who are also in the process of breeding by the time a year has passed. The cycle can continue like that for a year, or up to a maximum of 3 years, by which point you can have several hundred mice invading your home. Sadly, mouse breeding cycle is very quick and at just three weeks old, mice are already grown enough that they can damage your home and belongings.
They are already old enough to gnaw through food packages or start chewing on insulation, wood, and other items that may seem appealing. Unfortunately, the problem continues to worsen as they grow older and produce more babies of their own. Litters range from 3 to 14 mice, with the average sitting between 6 to 8. Also known as pups, baby mice are blind and deaf at birth. They weigh only 1 or 2 grams and are completely hairless. They begin to grow fur and teeth at one week of age, then open their eyes at 2.
At 3 weeks, they are weaned, then at 4, they hit puberty and weigh approximately 10 grams. Mice grow very quickly. Mice are polygamous and breed year-round. In the wild, they tend to breed more in the spring, when food is more widely available. In homes, they have no trouble breeding all year round. Males usually mate with several females at once, creating communal nursing groups in which one male protects the offspring of several females.
Mice are often quiet when their pups are first born, taking care of them around the clock. This often leads people to believe that the mice in their home have left, only to find several more emerging in the following weeks.
