House Mouse – A Complete Guide

house mouse


You may have come across the term “house mouse.” This is a common name for Mus musculus, also known as the grey field mouse or simply the house mouse. 

It can be found in many different parts of the world and has been around since prehistoric times. The house mouse was originally native to Europe, but it now lives all over the world.

The house mouse is a nocturnal animal that spends most of its time sleeping during the day. However, when food is available, they will wake up and start searching for food. 

They are very active animals and will often run through your home looking for food. Their diet includes seeds, nuts, and insects such as crickets.

The house mouse is an omnivore, so it eats both plants and animals. In fact, their primary source of protein comes from eating small amounts of meat. If you see them running around, you should not worry because they do this every night.

Where the House Mouse Lives?

Before humans started living in houses, the house mice lived in caves and other places where many food sources were available. As people began building homes, the house mouse moved into these new places and adapted to life indoors.

Ever since then, the house mouse has become one of our best friends. We use them to help us with pest control by trapping them and releasing them outside again.

House Mouse Appearance

The house mouse looks like a brown rat and has large ears and long whiskers. You can tell if it is male or female by looking at their genitals.

Male mice have two pairs of testicles, while females have no testicles.

House Mouse Behavior

Mice are social creatures and need company. When they get together, they sleep, eat, play, and mate. Mice are usually nocturnal and spend most of their time asleep.

When they are awake, they tend to move around slowly and quietly. The house mice don’t make much noise unless fighting with each other or trying to escape danger.

House mice are excellent climbers and jumpers. They can climb smooth surfaces and even ceilings.

Mice love to chew things and will gnaw on almost anything. They can break down wood, paper, plastic, cloth, rubber, and metal.

In addition to being pests, house mice are also crucial to human beings. They keep populations of harmful bacteria low and help to recycle nutrients in the soil.

House Mouse Reproduction

Female mice reproduce once a year. During mating season, males will try to attract females by making loud noises. Once the female is ready to mate, she will let her partner know by moving towards him. He will follow her until he finds her receptive vagina. Then he will mount her and copulate. Afterward, he will leave.

Male mice are smaller than females and have shorter tails. They may be able to produce sperm before they reach sexual maturity, which means that they can father many litters of babies.

Female mice give birth to 4-8 young ones. The mother carries them in her belly for about eight weeks. She nurses them for three days and then leaves them alone.

After this period, the pups start eating solid foods and begin exploring their surroundings. They stay with their mother for another two months. At this point, they will start leaving the nest and exploring the environment.

Once the young ones are old enough, they will take care of themselves. They will continue to live with their parents until they are mature enough.

House Mouse Habitat

There are several different types of habitats that house mice can live in. Some of these include:

  • Caves
  • Dryer vents
  • Garages
  • Houses
  • Paint cans
  • Under sinks
  • Wall voids
  • Woodpiles

Effects of House Mouse Infestation

  • Damage to Property

The damage caused by mice ranges from minor scratches to large holes in the floorboards.

  • Damage to Food

Mice can contaminate food supplies by chewing through packaging and contaminating stored grains, nuts, seeds, fruits, and vegetables.

  • Damage to Health

Some people believe that mice carry disease-causing germs. However, there is no evidence to support this theory.

  • Damage to Pets

Mice can cause serious problems for pets such as cats and dogs. They can scratch the animals and bite them when they attack them. In addition, mice can transmit dangerous diseases to your pet.

House Mouse Prevention and Control

We have various ways you can prevent and control house mouse prevention in your home, and they include:

  • Sanitation

Mice can thrive in an environment where there is food waste. Therefore, it is essential to clean up after yourself and your pets. You should wash dishes immediately after use and throw away garbage in sealed containers.

A clean environment helps to reduce the chances of attracting mice. If you see any signs of mice in your home, call us right away. We can provide pest management services to rid your home of mice.

  • Exclusion

If you notice holes in your walls or doors, it could mean that mice are living inside your home. To stop the problem from spreading, we recommend sealing all openings.

You can do this by using caulking. Caulking is a sealant used to fill cracks and crevices. It prevents water from getting into the wall.

  • Traps

To catch mice, you need to set traps. There are two main types of traps: snap traps and glue traps. Snap traps work by baiting the trap with peanut butter or cheese. When the mouse steps on the trigger, it snaps shut. 

Glue traps work similarly to snap traps, except that they stick to the floor instead of snapping shut. In both cases, the mouse gets stuck and needs to be removed manually.

  • Poisoning

To kill mice, you can use rodenticides. These are chemicals designed to make rodents sick. However, if you use too much poison, it can be harmful to humans.

Therefore, it is best only to use them when necessary. 

  • Mouse Proof Construction

The easiest way to keep mice out of your home is to build a barrier around your foundation. It includes installing metal flashing over the outside of your home.

Actually, this will help block moisture from entering your home. It will also allow air circulation, which keeps pests like mice out.

In addition, you can install weather stripping at every door and window. Weatherstripping is made of rubber or foam. It allows air to flow freely but blocks insects and pests from entering your home.

  • Bait Selection and Placement

When setting bait stations, remember that mice are attracted to sweet foods. The most effective bait for mice is peanut butter.

However, it is not recommended to place bait directly on the ground. Instead, it would be best if you put it in a container so that it stays moist.

When placing bait, you should avoid areas where people walk because they may step on the bait and tamper with it. 

  • Electronic and Sound Device

There are many devices available to deter mice. Some of these include motion-activated lights, ultrasonic repellents, and electronic fences.

Motion-activated lights come in different shapes and sizes. They turn on automatically when movement is detected.

Ultrasonic repellents emit sound waves that repel mice. Electronic fences contain sensors that detect movement. They then send a signal to a remote receiver that sounds an alarm.

  • Control by Dogs and Cats

Dogs and cats have been known to attack mice. Therefore, it is essential to teach your pet how to behave around mice. You can do this by training your dog or cat to stay away from food.

It is also possible to train your pet to recognize the scent of mice. For example, you can give your pet a piece of bread soaked in peanut butter. Your pet will associate the smell of peanut butter with mice.

By doing this, you will be able to tell whether your pet has caught a mouse. The mouse is an excellent snack for dogs and cats, so you can consistently offer them some after catching one!

Disposing of Dead Mouse

When disposing of these rodents, you should follow the instructions provided by local authorities. If you don’t dispose of them properly, you could end up spreading diseases such as salmonella and toxoplasmosis.

These diseases can cause serious health problems, including diarrhea, vomiting, and fever.

Don’t touch the dead animal with your bare hands; instead, wear gloves to prevent contamination. Then place the dead animal in a plastic bag and seal it tightly.

If you live near a landfill, you can take the dead mouse there. Otherwise, you can leave it in a safe area until you find someone who wants to dispose of it.

House Mouse and People

Mice are curious creatures. They love exploring new things. As a result, they often get into places that aren’t meant for them.

For instance, mice often enter homes through open windows and doors. In addition, they sometimes climb onto counters and tables.

They also love climbing on electrical wires. It makes them easy prey for electrocution.

Senses and Communication

Mice use their senses to identify potential threats. Their sense of hearing is particularly acute. They can hear noises as low as 20 Hz.

Meaning that if you play music below 20 Hz, you won’t disturb them. However, if you play music above this frequency, they might become agitated.

Their sense of sight is also good. Mice can see well in dim light and dark conditions.

As a result, they are active during daytime hours. During nighttime hours, however, they tend to sleep more.

Mice communicate using squeaks, chirps, grunts, and other sounds. These sounds help them to alert each other about danger.

In addition, they use urine and feces to mark their territory.


Mice rely heavily on olfaction. A good reason why they need to smell their surroundings before making any moves.

The odor molecules that make up their pheromones attract mates. It also helps them to avoid predators.

Mice can distinguish between scents that belong to individuals and those belonging to groups.

This allows them to determine whether they are alone or not.

Social Behavior

Mice are social animals. They live in colonies where members look out for each other. A colony usually consists of several generations of mice. Each generation lives together in the exact location.

However, when mice reach adulthood, they move away from the nest.

While living in the nest, mice have access to food, water, and protection. When they grow older, they must fend for themselves.

Mice also form friendships. They groom each other and share food.

They even play games like tag.

Do they Have any Use?

Yes, house mice are helpful. They eat insects and pests, which would otherwise damage crops and plants.

They also clean out nests and burrows. Finally, they control populations of harmful insects like cockroaches.

They are, in turn, used in laboratories to study genetics and development.

However, they are not considered pets because they are wild animals.
