Many of us get scared by weird sounds like scratching or thumping from above when it’s dark. These noises can mean animals are making themselves at home in your attic.

Different animals make different kinds of noises. Mice might make tiny scratching noises, while bigger animals like raccoons can make louder thumps. 

Paying attention to these sounds helps figure out what kind of creature is up there. It’s like a nighttime mystery in your own home!

In this article, we’ll help you understand what’s making those spooky sounds in your attic. We’ll look at the usual animal suspects and the noises they make. 

So without any fighter ado, let’s get started.

Key Takeaways:

  1. Different animals like mice, raccoons, and bats make unique noises in the attic, indicating their presence.
  2. Before assuming wildlife, check if attic fan or wind-caused noises are the source, as these can mimic animal sounds.
  3. Squirrels and flying squirrels are active at specific times, offering clues to their identity based on the sounds they make.
  4. Professional wildlife removal is crucial for safely dealing with attic animals, especially for protected species like bats.

What Is Making Sound in My Attic at Night?

If you’re hearing sounds in your attic at night, it’s likely due to animals such as mice, raccoons, squirrels, or bats. Each of these creatures has different sounds.

Attic Fan

Before jumping to conclusions, it’s important to consider if your attic fan could be the source of the noise. 

Consistent sounds, like a steady hum or whirr, often point to mechanical causes rather than animals. 

The wind can also play a role, causing loose parts of your home, like siding or roof pipes, to make noise. 

These sounds vary with wind speed and direction, so take note of whether the noise changes with the weather.


Once you’ve ruled out your attic fan and other structural causes, it’s time to think about wildlife. Start by inspecting the outside of your house. 

Look for obvious signs like a torn soffit or damaged roof, which could indicate a raccoon’s entry point. Also, check for loose siding or tree branches that might be causing noise.

A quick walk around your home can often reveal clear evidence of wildlife, like large holes made by raccoons. Racoons are some of the most common animals living in your attic.

What Animals Can Make Noise in My Attic at Night?

When it comes to identifying who’s making noise in your attic at night, there are a few usual suspects: squirrels, flying squirrels, mice, and bats. 

Each of these animals has its unique way of making noise, giving you clues to who they might be. Let’s discuss about these common animals in detail:


Squirrel in the Attic

Squirrels are mostly active during the day, particularly in the early morning and late evening. If you’re hearing noises in your attic during these times, it’s likely a squirrel. 

The sounds you’ll hear are scampering, scratching, and sometimes rolling noises as they move acorns or nuts. They can also make gnawing sounds similar to mice.

Flying Squirrel

Unlike their daytime cousins, flying squirrels are active at night. If you hear soft thumping, it could be them jumping around. 

They often enter through small gaps in your roof, so if you hear noises from up high, flying squirrels could be your guests.


mice are common attic visitors, known for their light footsteps and scratching sounds. You might hear them scurrying across your attic floor or gnawing on wood. 

These rodents are especially noisy at night, making them a frequent cause of nocturnal attic sounds. 


Bats, seeking shelter for birthing and from the cold, often reside in homes. They only need a small opening to get in. 

If you hear squeaks, chirps, or fluttering in your attic, it might be bats. They usually roost in wall cavities or attics, so these sounds can sometimes be heard from within your walls.


Raccoon in the Attic

Raccoons are a common source of attic noises, especially at night. In spring, they look for safe places to give birth and raise their young, leading to a variety of sounds. 

Thumping, banging, or knocking might mean a raccoon has made your attic its home. The soft mewing or whining noises could indicate baby raccoons are present. 

As the babies grow, expect louder thumps and occasional snarls. Raccoons are determined and can create entry points to return to their kits, making professional removal a wise choice.


Bird sounds in the attic, like frantic flapping or chirping, usually mean they are building nests or roosting. The presence of birds is easier to identify during the day due to their vocal nature. 

With more pigeons finding their way into attics each year, it’s important to look out for nesting signs.


Opossums in the attic might be quieter than other animals, but they leave behind noticeable signs, such as large droppings and trails through insulation. 

If you do hear sounds, they’ll likely be slow, shuffling movements. Opossums are mostly solitary, seeking shelter in colder months or when mothers need a safe place for their young. 

They require larger openings to enter, so significant gaps might suggest an opossum visitor to your house.


While snakes are less common animals in the attic, they can still be a source of concern. 

Unlike mammals, snakes don’t make much noise themselves, but their presence can be detected through signs like shed skins or occasional slithering sounds. 

Snakes may enter attics in pursuit of prey, such as rodents, and usually find their way through small openings or gaps.

How To Identify Animals in the Attic By Noises?

How To Identify Animals in the Attic By Noises

Finding out which animal is in your attic can start with just listening to the sounds they make. Different animals have their own kinds of noises.

Pay attention to the sounds. Mice and rats make scratchy noises and move fast, so you’ll hear something like tiny feet running. 

Squirrels, which are awake in the daytime, might make noises like chattering or sounds of nuts rolling around.

Looking at animal poop can also give you hints. Rat poop is small and sharp, while squirrel poop is bigger and rounder. 

The kind of mess they make can tell you who they are too. Rats chew on things like wires, but squirrels might chew on wood or make holes.

You can also look for footprints. Rats have smaller front feet, and squirrels’ feet are all the same size. 

If you still can’t tell, a camera that takes pictures when it sees movement might help catch the animal in action. This will help you find which type of animal in your attic is making the noises.


What to Do if You Hear Something in the Attic?

Identify the sound type and timing, inspect your home’s exterior for entry signs, and avoid confronting the animal. Consult a professional wildlife removal service for safe and effective resolution.

Is It Ok to Leave Bats in the Attic?

No, bats in your attic can damage structures and pose health risks. Removal should be done by professionals due to legal protections for bats.

What Will Scare a Raccoon Out of an Attic?

Bright lights, loud noises, or predator scents like ammonia can deter raccoons, but sealing entries is important. Consider professional help.

Why Does It Sound Like Someone Is Running in My Attic?

This is often caused by small animals like squirrels or rats moving quickly, searching for food or nesting. Seal entry points to prevent access.

What Is Making Noise In My Attic During The Day?

The noises during the day are likely caused by diurnal animals like squirrels. They’re active, especially in the early morning and late evening, making sounds such as scampering, or scratching, which can be quite loud.


In conclusion, the mysterious noises in your attic at night can come from various animals, each with its unique sounds. 

Raccoons with their thumping, birds chirping, opossums making less noise but leaving visible trails, and even the rare presence of snakes can all be the source of those eerie sounds. 

Identifying these noises correctly is crucial for dealing with unwanted attic guests. Taking action is important, whether it involves sealing entry points or consulting with wildlife control experts. 

Keeping your attic free from animals not only ensures a peaceful night’s sleep but also protects your home from potential damage.
