Mouse facts

To a mouse, your home looks like the perfect place. Here are some mouse facts for you to keep in mind.

  • Mice are rodents found wide and varied all over the world. They can vary in color and their size can range from about three inches to up to seven inches in length.
  • Mice are great at getting into small spaces and can wriggle through a crack or hole that is as small as a half-inch wide.
  • Their bodies are collapsible, allowing them amazing access through even the smallest hole.
  • Some mice are great at jumping.
  • Most mice are very good swimmers.
  • Mice like warm places. That's why they become such a problem during the colder fall and winter months. They look for warm, hidden, places where they can build nests and give birth to their pups.

Mouse habits

Mice have a lot of habits that make them tough pests to deal with. However, to know for sure that you have a mouse problem, it pays to know what these habits are.


Mice are great at chewing.

  • Their teeth are designed to chew through things like fruit and grinding up seeds and grains.
  • Their teeth are also really great for chewing through harder materials such as wood and rubber.

That's why they can chew their way through the wood of your home, or gnaw a hole in the rubber at the bottom of the garage door to get inside.

Building a nest

A mouse wants to build a nest. Remember:

  • If you have cardboard boxes, newspapers, magazines or paper lying around, a mouse will find that a perfect place to visit.
  • Mice can get into the walls and chew on the rubber lining of electrical wires, which often leads to them chewing on the wires themselves.

Mice are not eating these things for food. They are shredding and chewing the paper and other things to build a nest somewhere. They want that nest to be as warm and cozy as possible to house their pink-colored pups until those become full-grown mice capable of surviving on their own.

Searching for food

When mice go looking for food in your home they can chew through containers and bags, so one of the first signs of mice that you might see are holes in bags or containers. Keep in mind:

  • Mice are omnivores, which means they will eat almost anything, but their favorite meals are grains, seeds and fruit.
  • Bags of rice, seeds, flour, cereal and more can all become meals for ravenous mice.

Nocturnal and territorial

Mice are nocturnal. If you have them in your home you are more likely to hear them running around or chewing on things after the sun goes down.

A mouse can be very territorial, trying to keep other mice away from their nests and feeding grounds.


Finally, mice are very shy when it comes to people. They would rather not be seen, so they will run if they see you. When they run they prefer to stick close to the walls because they have poor eyesight and that big living room is hard for them to see across.

Mouse diseases

The problem is that mice are messy. They will leave urine and feces all around their nests. Mouse and rodent urine and waste materials carry diseases and viruses, plus mice often carry their own pests with them and they can transmit disease, too.

Some of the diseases that mice carry include:

  • Salmonella - if mice get into your food they can leave the salmonella bacteria behind. This can become a very, very serious form of food poisoning that causes stomach upset and can lead to a visit to the hospital if it gets serious enough.

  • Hantavirus - a hemorrhagic disease that can transmit to people who end up handling mouse feces and urine. If not properly treated this disease can be fatal.

  • Lymphocytic choriomeningitis (LCMV) - a deadly disease that affects the lining of the brain and spinal cord. Your average house mouse carries this disease naturally and will pass it on to offspring. Mice spread it via their urine.

  • Tick-borne diseases - most mice end up infected with parasites such as ticks. Once ticks get into your home they can find their way onto you and can cause diseases such as Lyme Disease, Typhus, Rocky Mountain Spotted Fever, Colorado Tick Fever and more.

Do you need mouse control?

If you find signs of mice in your house, from hearing or seeing the mice, to finding the droppings to finding shredded paper, you need to call in a professional.

A professional mouse exterminator will find where they are hiding, eliminate them completely and prevent them from returning.
