Why Would Mice Be In Your Bedroom – 3 Reasons

Why would mice be in your bedroom

Let’s face it. If there’s a mouse or a bunch of mice in your bedroom, they’re there for a reason. 

Here are the top three reasons for a mouse to be in your bedroom –

  1. The mouse has an active nest in your bedroom
  2. It accidentally entered your bedroom
  3. There’s a mice infestation in your home

Let’s get into each of them.

There’s A Mouse Nest In Your Bedroom

Think again if you’ve ever thought that mice make their nests only in attics, basements, or inside the wall cavities and gaps.

Mice can also make nests in your bedroom.

Mice will target the coziest and the most cluttered places inside your bedroom to build their nests.

So, places like the storage section underneath the bed, wardrobe, closet, and even drawers can be a nesting place.

These places store fabric, don’t get any natural light and are cluttered.

That makes these places a perfect place to build their nests. Mice will chew or shred the fabric in these places to create a comfortable nest for their babies.

But there’s a catch.

It doesn’t happen all the time.

Mice will target a bedroom to build their nests if it is unoccupied for a considerable time.


It’s because mice are shy. They try their best to avoid humans.

So, if you’re using your bedroom daily, then chances are that mice won’t make your bedroom their go-to nesting place.

However, clutter can make your bedroom attractive to mice and bugs like spiders.

The Mouse Accidentally Entered Your Bedroom

Have you ever wondered why there’s a mouse in your bedroom despite no food around?

It’s because the mouse accidentally entered your bedroom.

The accidental intrusion of the mouse in the bedroom is the most common reason for sighting a mouse in the bedroom.

The mouse might have been on its way to scavenge for food in the kitchen. 

And on its way back to its hiding place, it accidentally entered your bedroom. 

It happens a lot during the night when your switch off the lights. 

Mice are nocturnal creatures. They do most of their scavenging activities during the night.

At night, you might hear the squeaking sound of the mouse or a scratching sound that wakes you up.

On turning the light, the mouse runs out of your bedroom and hides somewhere else in the home. 

Mice can also enter your bedroom if there are food crumbs or any unpacked edibles like chocolate or potato chips in your bedroom.

These foods will draw the mice into your bedroom too.

When you get startled by the mouse’s presence, the mouse gets scared. 

That makes the mouse hide in your bedroom and refuse to come out. 

That’s why it’s always best not to panic when you see a mouse in your bedroom. It’s better to chase the mouse away.

There’s A Mice Infestation In Your Home

Mice infestation in your home is more of an overarching reason for a mouse to be in your bedroom.

When the infestation level increase, the number of mice in the house also increases.

That causes a shortage of hiding places.

The mice become more exploratory and look for alternative places to hide.

That makes them intrude into places like bedrooms, living rooms, and even inside cars. 

If you often see mice in your home, then it’s high time to take action or call a pest controller to get rid of them.

5 Signs Of Mice Infestation In Your Bedroom

Signs of mice in bedroom

Mice can be in your bedroom even before you spot them physically. 

However, there are sure signs of mice in homes and bedrooms that you will encounter if they’re in your residence.

Here are the five signs of mice in the bedroom –

  1. Mouse droppings
  2. Mouse urine odor and urine stains
  3. Smear marks along skirting boards, vents, and holes
  4. Squeaking sounds coming from the walls and ceiling
  5. Chewed clothes and fabric in places like your wardrobe and dresser drawers

Let’s take a deep dive into each of them and find out why and where you find these signs of mice in your bedroom.

Mouse Droppings

Mouse Droppings

Mice defecate nearby their nests. And they don’t go beyond 10-25 feet from their nests.

So, if you see mouse droppings in your bedroom, then it’s a telltale sign that there are mice in your bedroom.

Those mice are hiding in the cluttered places in your bedroom and home. 

If your bedroom is cluttered, mice can take hide in your bedroom.

You’ll notice mice feces in the tight corners of your bedroom and bedroom storage sections.

One of the most common places, which many people ignore, where mice build their nests and hide in the bedroom is the storage section underneath the bed.

In many homes, the storage section underneath the bed is cluttered stuffed with fabrics, blankets, and even cardboard boxes.

They make it a perfect place for the mice to hide. 

Also, they’ll take shelter in your closet drawers, dresser drawers, and wardrobes. 

These storage sections contain linen and fabric. These are soft chewing materials, and mice use them to build their nests.

Mice and rats prefer to build their nests out of fabric and paper because it’s comfy for their babies.

If the bedroom is lying vacant for weeks, then mice droppings on the bed are also possible. 

Also, eating snacks or food on the food will lead to food stains and food crumbs droppings on the bed. 

It will attract the mice to your bed and other bugs like bed worms and ants.

Mouse Urine Odor And Stains

The stench of urine is quite strong in homes with mice and rats.

Mice will urinate too. And the stinking urine emits a smell strong smell of ammonia.

Your bedroom will be reeking of the mice’s urine odor, especially when the mice have been living there for a long. 

Urine stains will be visible on the bedroom floor, along the baseboards, on your bedroom furniture legs, and in the worst-case scenario, closet or wardrobe.

When mouse urine is fresh, it looks bluish. As it grows stale, it turns pale, and the dust deposits on the urine can also make it greyish.

Smear Marks On Skirting Boards, And On The Edges Of Vents And Holes

Rodents like mice and rats inhabit dirty, damp places when they’re outdoors.

Their bodies always carry those greasy dirt deposits that stick on their bodies because they inhabit dirty places like drains and sewer pipes.

When they enter homes, they pass through the entry points like vents or create holes in the porous section of the walls to get inside.

In doing so, they leave behind those greasy deposits on the vents and holes.

Also, mice and rats scratch themselves on hard objects. 

They’ll do it while they’re in your home. And they’ll leave behind greasy smear marks on skirting boards, baseboards, and on the edges of toilets, bathtubs, and furniture. 

Those grease marks look greyish. And you may also notice mouse paw marks on the grease marks. 

These smear marks can also be visible in your bedroom, especially when the infestation is fresh. 

Those mice have recently entered your home and bedroom outdoors, and they still have those dirt deposits on their bodies.

These smear marks carry pathogens and allergens that can cause severe health issues.

Squeaking Sounds Coming From The Walls And Ceiling

You’re no stranger to mouse squeaking sounds. It’s a clear sign that there’s a mouse in your home.

And when the mice are in the bedroom, these squeaking sounds become audible, especially at night.

Mice are nocturnal, and they perform all their foraging and scavenging activities at night.

Mice can get inside the bedroom’s walls and even in the ceiling. Moisture damages the walls and the ceilings making it easy for rodents to dig cavities and hide.

Many mice get stuck in the wall cavities. They fail to move out of the holes and starve to death because they didn’t get to access a food source.

Many homeowners notice dead mice in the wall cavities and places like attics and basements.

Chewed And Shredded Fabric In Places Like Your Closet, Wardrobe And Dresser Drawers

Mice and rats love your clothing storage areas.


Those places are cozy, soft, and comfy for their babies.

These aspects make them an ideal place for them to build their nest.

Mice in the bedroom will target your clothing storage areas to build their areas.

When they figure out certain closet sections and wardrobe sections don’t get much human intervention, they’ll target them to build their nests.

Mice in these places will shred the fabric you store to build a nest for their babies. 

That leads to expensive damage and contamination of living rooms with deadly pathogens.

How To Scare A Mouse Out Of Your Bedroom?

To scare the mouse out of your bedroom, it’s essential that you don’t get scared of the mouse.

Then it becomes easy to chase the mouse out of your bedroom.

Make loud noises by tapping on the floor heavily with your foot, stick, or clap with your hand and chase the mouse. 

Keep the bedroom door open.

While doing it, you can make the mouse hide behind things in your bedroom. 

Don’t be afraid to rattle the things behind which the mouse is hiding.

The mouse will not, in any case whatsoever, turn back to bite you.

Continue the chase, and the mouse will run away through the open bedroom door.

But please don’t try to grab the mouse. It can bite you out of self-defense.

How To Prevent Mice From Entering Your Bedroom?

To prevent mice from hiding in your bedroom, you must take specific steps that stop mice from invading your home. 

Below are the five steps you can take to evict mice from your home and prevent them from coming back. 

Step#1 – Use A Peppermint Essential Oil Spray In Your Bedroom And Home

Mice and rats hate the strong scent of peppermint.

And research has proved that peppermint has bug and rodent properties that you can use to keep your home safe from rodents.

There are two ways to use peppermint essential oil to keep mice away.

The first is to use a peppermint spray for repelling rodents and mice.

Spray it in your bedroom and in places where mice and rodents invade the home.

The typical entry points for mice are gaps, holes, and vents in –

  • Kitchen and kitchen storage areas like kitchen cabinets and kitchen pantry
  • Fireplace
  • Around doors and windows
  • Pipes under sinks and washing machines
  • Pipes going to water heaters and furnaces
  • Floor vents and dryer vents
  • Attic
  • Basement
  • Crawl space
  • Plumbing section in laundry rooms and garage

You can also prepare a peppermint essential oil spray by mixing 11-13 drops of pure peppermint essential oil in water. 

Spray it on the places listed above.

The second way is by soaking cotton balls in the peppermint essential oil and keeping them near these entry points.

That’ll also keep the rodents from sneaking inside your home. 

Step#2 – Use Weather Strips To Close The Gap Between The Bedroom Door And Floor

Mice can crawl through the tightest of gaps and holes.

And they can sneak inside your bedroom even if you’ve closed the bedroom door.

Mice will crawl through the thin gap between the lower edge of the door and the floor.

So, close that gap.

You can close that gap by using weather stripping or a door sweeper

You can also close the gaps between the door and the door frame by using weather stripping.

If there are windows in your bedroom, then keep the windows closed, especially when the window is facing a tree or your yard.

Mice and rodents can use the tree as a bridge to sneak inside your bedroom through the open windows.

Mice can also jump. So, they can also jump from a tree branch straight inside your home through an open window.

If you’re used to sleeping by keeping the windows open, use a window screen with a strong mesh. 

That’ll prevent mice, rodents, bugs, and flies from entering your bedroom through the open windows.

Step#3 – Keep A Mouse Trap Outside Your Bedroom

Mouse Trap Outside Your Bedroom

There are many types of mouse traps available. 

Glue traps, snap traps, and humane traps are common rodent traps that you can use in your home and bedroom to trap the hiding mice. 

Using mouse traps to catch mice inside the home is an old-fashioned yet effective way to eliminate mice inside homes.

The first two steps will ensure that mice won’t intrude into your bedroom.

However, as an extra layer of security, keep a mousetrap a few feet away from the bedroom door.

Keep the trap close to the floor’s baseboard because it’s along the baseboards and corners that mice travel at night.

Lay the trap at night before going to bed because mice and rats venture out at night. 

You can use some peanut butter or a tiny piece of cheese on the rat trap. 

The mousetrap will catch any mouse that steps on it. 

A mousetrap with the right bait is one of the sure-shot ways to lure a mouse out of hiding.

There is also rat poison available.

You can mix the poison with candy or cheese and leave it for the mice to eat. Or leave the poison bars as is.

But if you’re using rat poison, wear gloves and a mask.

It’ll ensure that the rat poison doesn’t contact your skin directly and you don’t inhale it. 

Wash your hands with soap after using the rat poison.

If mice are showing up in your bedroom and home despite using traps and baits, it’ll be best to hire a reliable pest control for mice inspection. 

Step#4 – Keep Your Home And Kitchen Clean

Mouse In The Kitchen

Cleanliness goes a long way in protecting your home from rodents and bugs.

And the more food wastes are there in your home more appealing your home is for mice and rats.

The smell of food waste will draw the mice into your home and will cause them to take permanent shelter in your house.

So, keep your home, especially your kitchen and yard, clean.

Ensure that the trash bins don’t hold the garbage and food wastes overnight. 

And you don’t keep plates and utensils with food stains in your kitchen sink.

The rotting smell of the food waste from your kitchen draws not just mice, but also invasive bugs like ants and roaches to your kitchen and home.

Mice can contaminate stored food which can lead to diseases like leptospirosis. 

Mice and pantry pests can easily chew through the flimsy and weak food storage containers to access the stored food.

Please ensure that you store pet food and foods like grains, cereals, flour, and dry fruits in air-tight and robust food storage containers.

Keep bay leaves or cinnamon sticks on your kitchen shelves as an added layer of protection.

Bay leaves and cinnamon repel bugs and rodents.

Step#5 – Seal The Possible Entry Points Of Mice And Rodents 

You can’t seal and close all the holes and vents in your home.

However, caulk as many of them as you can.

Keep an eye for spotting gaps and cracks on the walls, window frames, and door frames. 

Mice can easily squeeze through these places and sneak inside your home.

If you find any, seal them.

Also, seal the crevices on the walls. Those crevices become the entry points for mice and bugs in the walls.

They even build their nests in the walls too.

If your walls are damaged by too much moisture, repair the wall asap. 

Use rugged screens with robust mesh for the attic, basement, bathroom, and garage vents. 

Mice exploit these vents to sneak inside human residences.

Should You Let Your Cat Hunt Down The Mice?

Do Cat Eat Mouse

Cats are natural predators of rodents like mice and rats.

And they’ll hunt down any mice hiding in your bedroom and your entire home. 

But there’s a downside to it.

Your cat can eat mice. And your cat can fall sick after consuming the mice.

According to Animal Medical Center, mice carry roundworms which can infect your cat if your cat eats the mice.

Mice also carry parasites and pathogens that can be deadly for your cat and you.

For example, your cat can get toxoplasmosis. It’s caused by the parasites that filthy rats and mice carry. 

So, despite many people saying that your cat will hunt down the mice in your home, you shouldn’t let your cat do the work for you.

It’ll be best to follow the steps laid out in the post to remove the mice in your bedroom and your home.

Can Mice Climb On Beds?

Yes, mice can climb on beds. But if you’re sleeping on the bed, they won’t mount on the bed.

It’s because mice are shy and scared of humans. They try their best to avoid human contact.

But if there’s no one on the bed, and the bedsheet is dirty with food stains, it can make the mice climb the bed.

Will Mice Crawl On Your While You’re Sleep?

No, they won’t. Mice will instead get out of your room if they don’t find any reason to stay in your bedroom.

If there’s no nest in the bedroom or no food, the mice will go away from your bedroom. 

Is It Safe To Sleep If There’s A Mouse In Your Bedroom?

Yes, it’s safe to sleep if there’s a mouse in your bedroom. The mouse will not crawl on you. 

But the scratching sound that mice produce when they chew on things and the shrill squeaking sound can make you lose your precious sleep.

Will Sleeping With Lights On Keep Mice Away?

Yes, sleeping with the light on will prevent the mice from entering your bedroom. 

It’s one of the most common practices that many people use.


Because mice prefer darkness to forage or explore, they avoid bright places.

So, if you’re sure that there are mice in your home, then shutting the bedroom door and sleeping with the lights on will keep mice out of your bedroom.

Do Mice Bite?

Mice bite humans, but in the rarest of rare cases, when they feel cornered or threatened. 

So, while getting rid of the mice, ensure that you handle them. 

Mice carry pathogens, and their bite or exposure to their droppings can cause diseases like Hantavirus Pulmonary Syndrome.

It’s a respiratory disease that causes contraction and pain in the muscles. 

Another disease that mice bite can cause is rat-bite fever. 

The symptoms include headache, dizziness, breathing problems, muscle pain, and rashes in both cases.

But, as mentioned earlier, mice are shy, and they’re not aggressive. So, mice will not bite you despite being around you and hiding.
