What Noise Do Rats Make 8 Common

What Noise Do Rats Make?

Here we are going to cover all of the noises that rats make. These noises can be heard if a rat has entered your property. They are also the noises that rats make, such as squeaking.

I wanted to cover both because it is important to understand them and their differences.

Rats are known to hiss. I have witnessed a hissing rat on more than one occasion, so I am familiar with the sound.

It cannot be comforting when you first hear it, especially if you tentatively walk around in an attic with minimal light! That is what happened to me. Of course, the automatic reaction is the best, and that is to freeze!

That is exactly what the rat wants you to do; freeze and back away!

Why do rats hiss?

A rat will hiss to warn you off, signifying that the rat feels threatened and that you should back away.

Having said that, if a rat is in your home and you want to get rid of it, why should you back away from a hissing rat? You want the rat to feel threatened in your home. It may decide to move out…


This is a very common noise that rats make, and it is one that I am sure is no surprise to you!

Why do rats squeak?

A rat will squeak for several different reasons. Usually, the short squeaks and rats are simply communicating. You may also find that a rat will squeak if you startle it, but it doesn’t feel threatened enough to hiss at you.

What noise do rats make? Squeaking is definitely one of the most common!


You may or may not believe this one! I didn’t believe it until I heard it myself. Rats can make a noise that sounds a lot like a bark!

Some say the bark is more of a cough or a heavy huff. Either way, it sounds like the rat is barking at me.

Why do rats bark?

I heard a rat barking because I had caught it in a live-catch rat trap. The rat was barking when I got too close to the trap.

I imagine the rat was barking because it was scared or was trying to warn me off.


This one scared the living daylights out of me when I first heard it. I have very close to the rat at the time, which is why it was so terrifying.

Screams for a rat are close to a squeak but with more venom (at least, it sounds that way).

Why do rats scream?

This particular rat screamed because I strayed far too close to it and the nest it was protecting.

If you hear a rat screaming, someone is getting too close, and the rat wants to let them know that it is near and will attack if necessary.

Grinding Teeth

Yup, rats grind their teeth! You must get close to the rat to hear it doing this. You are unlikely to hear it from a wild rat because they will make more threatening noises if you get too close!

If you have a pet rat, you may hear this.

Why do rats grind teeth?

The theory is that rats grind their teeth to keep them at a decent length. Of course, you may or may not know that rat teeth constantly grow! Grinding them might be a way to keep them at a decent length.


Ok – we will now move on to some of the noises you might hear a rat making around your home, starting with scratching. It is one of the common rat noises you will hear in your attic that signifies the start of a rat problem.

Scratching is a common sound when a rat finds an entry point to your home!

Why do rats scratch?

Rats scratch because they are finding routes through your home. Now they have found their way in; the next step is for them to discover and remember routes they can use to travel throughout your home. They will be scratching at walls to try to create routes.


This is the most common rat noise you will hear in your home. Sometimes, it sounds like a much bigger animal traversing the darkened spaces in your home, but it is likely to be a rat.

They are scurrying around in your attic, in your basement, and even in your cavity walls.

Why do rats scurry?

Simply put, rats have found some routes they can travel through your home. For example, I recently visited a friend’s home, and they could hear rats in one wall and trace it as they climbed (rats are excellent climbers) right up to the attic. After sundown, this noise was unbearable. I looked outside their home and found a rat entry point at the wall entrance.

We watched the entry point from inside the house and sealed the hole as soon as the rat left, searching for food. After checking around the rest of the house, I was confident that was the only entry point. They never heard from the rat again, but they did have quite a bit of rat urine to clean up!


I mentioned above that rats have ever-growing teeth! To keep these monster teeth under control, rats need to gnaw tons of items.

Rats can gnaw through pretty much anything, and you must be very selective when storing food (I use round glass containers).

Why do rats gnaw?

Simply put, rats gnaw through things for one of two reasons:

  1. They need to keep their teeth in check.
  2. They want to access something.

What noise do rats make? Gnawing is one of them and is one of the most common.
