Mice are enthralling creatures with a lot more to them than meets the eye. To begin with, did you know that house mice can be quite resourceful?

They are well-known for their ability to navigate in the dark. They are also very social animals, meaning they prefer to live in groups.

In fact, when it comes to living in groups, mice are very similar to humans! They, like us, have various personalities and roles within the group.

Intrigued? Continue reading to discover 8 fascinating facts about mice that will change your perspective on them.

Fascinating Mice Facts

Fact #1

You may be surprised to learn that there are an estimated 21 million mice living in homes across America right now. These pesky creatures typically enter homes between October and February looking for food, water, and warmth.

So, if you have a mouse problem, know that you are not alone. However, while mice are generally considered to be harmless, they can cause a lot of damage and spread diseases if they’re left untreated.

Fact #2

Mice are excellent climbers, jumpers, and swimmers. Mice, in fact, can jump a foot into the air, allowing them to easily climb up onto kitchen counters or into pantries to get to the food. To keep mice and other pests out of your food, keep all pantry items in hard, plastic containers with a tightly sealed lid.

Mice are also excellent swimmers and can easily navigate through the water to get to food or shelter. In fact, mice have even been known to swim up the discharge pipes of dishwashers and other appliances in search of food or a place to nest.

To help keep mice out of your home, make sure all drains are properly sealed and that there are no cracks or holes in your foundation or around your doors and windows.

Fact #3

Mice may be small and seemingly innocuous, but they can actually carry some pretty dangerous diseases. In fact, mice can spread as many as 200 human pathogens! But that’s just the beginning. Mice can also contaminate food with their urine and feces, which can cause all sorts of problems for humans.

In fact, research has shown that mice are responsible for more than $2 billion in damages each year!

For example, did you know that Hantavirus is a serious mouse-borne illness? It can cause fever, muscle aches, and even death in some cases. And if that’s not bad enough, Salmonella is another nasty disease that mice can transmit. It can cause abdominal cramps, diarrhea, and vomiting – not exactly the most pleasant experience.

That’s why it’s so important to take precautions when dealing with them and take action right away!

Fact #4

Mice are notorious for having voracious appetites. Mice eat between 15 and 20 times per day, despite their tiny bodies (and even smaller stomachs!). They prefer to build their homes near food sources due to their frequent eating habits.

Mice are known to invade pantries and cupboards in search of food, which can be a problem for humans. It has, however, provided an opportunity for one enterprising mouse family, who has set up shop right next to the refrigerator.

The refrigerator is always stocked with fresh food, and the mouse family has quickly mastered the art of raiding it for snacks. They’ve even devised a system that allows them to enter and exit without being noticed. They’re clever little buggers!

Fact #5

Mice are cunning creatures. They can fit through openings as small as a dime, so even the smallest crack or opening on the exterior of your home is like an open door to them.

But don’t worry, there’s an easy fix! Seal any exterior openings with silicone caulk to prevent mice from entering your home. Steel wool can also be used to fill gaps and holes in your home. They won’t be able to chew through steel wool, so any entrances they may use to get inside will be sealed.

Fact #6

Who knew house mice generated so much waste? I certainly didn’t! However, they appear to be capable of producing up to 100 droppings per day. Yuk! Furthermore, as they move around their territory, they constantly expel micro-droplets of urine. Gross!

However, there is a bright side to this story: house mice (like all rodents) do not vomit. Phew! So we don’t have to be concerned about them puking all over the place.

Fact #7

Why do mice live such brief lives? It’s not like they’re taking any risks. In fact, mice spend the majority of their time in their nests, eating and sleeping. So, what’s the story?

Some researchers believe it has something to do with the mouse’s natural predators. Mice in the wild must contend with cats, snakes, and foxes. These animals are constantly pursuing and killing them.

Mice, on the other hand, don’t have to worry about any of that in a lab setting. They are safe and can live for up to two years.

Fact #8

A female house mouse can give birth at the age of two months and can have up to a dozen babies every three weeks. This means she could have up to 150 children in a single year!

The baby mice are born blind and deaf, weighing only a tenth of an ounce. They spend the first two weeks of their lives in their mother’s nest before venturing out into the world. House mice are highly social creatures that live in colonies. A colony can contain anywhere from a few dozen to hundreds of mice.

So, if you see a mouse in your house, it is safe to assume that there are more or that more will appear soon.


Mice are fascinating creatures, and there is still so much to learn about them. As we continue to study these little rodents, we may be able to unlock more secrets about human health and disease.
