Mouse Math – How Often Do They Multiply?

Signs You May Have Mice in Your Home

Mice and rats and grow in numbers in literally no time!  An infestation can get out of hand quickly before you even notice it.

Some common signs you may have rodents in your home that you should be on the lookout for are scratching sounds and urine smells.  Other signs include scratch or bite marks on things, droppings and grease marks, and urine pillars.

Mice like the night so it’s likely you haven’t even spotted one.  But don’t underestimate their power.  They can damage your property with their nasty habit of gnawing, and not to mention the diseases they carry are extremely harmful to your health.

How Often Do Mice Reproduce?

As we said, mice and rats are breeding machines!!! They have a gestation period of 19 to 21 days. A female on average gets pregnant about 5 to 10 times each year and she can give birth to 3 to 14 pups. The litter size can range from 6 to 8 pups. So, you’re looking at at least 32 to 56 pups each year from one little female.

The mother can also mate immediately after giving birth. So you could be looking at a new litter within just 25 days. To make matters even worse, the female baby can reproduce at 6 weeks! So, they can start producing pups of their own and have about 10 litters of their own per year.

In a pretend scenario, two mice that sneak into your home could give birth to 60 pups in a year. Of these new mice, about 21 to 30 are females capable of having their babies within a month, which can theoretically lead to 5,082 mice in just one year. One mathematician calculated it to be 5 million mice per year, that is if it were a perfect mouse world.
