How Often Do Mice Reproduce?
Female mice become sexually mature at just six weeks old. Gestation lasts between 19 and 21 days, and females can get pregnant again immediately after giving birth. This rapid reproduction rate means that having a single pair of mice in your home can spiral into a full-blown infestation within two months, and once the female babies reach maturity, the problem gets even worse.How Many Babies Do They Have Per Litter?
One litter of pups can consist of up to 14 pups. While small litters of as few as three pups sometimes happen, the average number of babies per litter is eight. Female babies reach maturity less than two months after birth, so if you don't have a plan for mice control, you'll easily be dealing with dozens of mice in just a few months.How Many Litters Do Mice Have a Year?
Each female mouse can get pregnant again immediately after giving birth. It's possible for a mouse to get pregnant up to ten times a year, and almost all female mice have at least five litters each year. In the wild, most mice only live for a year, so you may only see 10 litters total throughout a female's lifetime. However, mice commonly live for two and even three years if they take up residence inside, so each female is capable of having up to thirty litters during her lifetime. For this reason, you need to contact a professional at the first sign of an infestation. Call for help if you notice:- Strange noises in the wall
