How do you know when all the mice are gone? How do you know if your safe from all the diseases that mice can bring to your home?

So many questions… In this post, I am going to give you some tips for how you can be sure that all the mice have left your home!

How do you now when all the mice are gone

When your home is infested with mice, it is a bad situation.

If you are like me, then you will have problems sleeping (pesky mice keeping you awake!) You will also become obsessed with every little noise that you hear around your home.

Sounds in the walls, sounds in your attic, your cat, or other pets acting strange! These are all signs that you have a mice infestation.

But…now you think you may have cracked it, right? Do you think you might have got rid of every mouse that has infested your home? Your DIY pest control has worked! Or, has it?

Let’s have a look at the things you can do to know, 100%, that all the mice have gone and you can forget the mice infestation you have just battled with.

How Do You Know When All The Mice Are Gone?

Want to know how to tell if mice are gone from your home? The biggest clue is that you no longer hear mouse-like noises in your home.

There are other tests you can perform to ensure they are gone, such as checking for nests, checking for mouse droppings, or leaving mouse traps around your home.

You can even use some talc or flour to check for footprints! Follow the guide in this post to increase your confidence that all the mice have left your home.

How to Tell If All The Mice Are Gone – Our Guide

If you are asking yourself the question:

How do I know if the mice are gone?

Then check below for the things you can do to confirm it…

No More Noises

The biggest give away is when you have not heard any noises for a week or so.

One of the most common signs that you have mice is hearing scratching or scurrying noises in your attic. Whilst these noises are mostly heard at night, you may hear noises during the day too.

If you last heard scurrying or scratching noises over 1 week ago it is a great sign that all the mice have gone.

It goes without saying that if you hear noises (mostly at night, because mice are nocturnal) then you still have an issue with mice. It’s not time to stop the rodent control just yet I am afraid…

Check For Nests

It is time to go on a hunt for mouse nests! If you find a nest, then you could be facing a mouse infestation.

Check all of the common places that a mouse will hide in your home, and scour the local area for any signs of a nest.

You a looking for an area with a lot of chewed items, usually buried deep in your insulation material in your attic!

Other signs include a larger than usual amount of mouse droppings and a strong smell of mouse urine.

Mouse Droppings

Searching for mice droppings is a great idea if you want to know if all the mice have gone.

When you are sure there are mice in your house, you should always pick up any droppings as soon as you find them. There are two reasons for this:

  1. It will lower the chance that you will contract a nasty disease.
  2. You will notice any fresh droppings, indicating the mice are still around!

Always ensure that you clean the area thoroughly too.

When you have not seen any mice droppings for over 1 week, it is a sign that the mice have all gone.

If you see lots of mice droppings, then you still have a mouse infestation… time for some DIY pest control!

Gnawed Items

Take note of all of the gnawed items you see during the mice infestation.

There will be plenty of them, especially in your attic or basement!

When you notice the lack of freshly chewed items, it can be a sign that all the mice have left your house.


It is fair to say that mice come with a very distinctive odor! It is even worse when you stumble upon a dead mouse!

Mice stink… There is no doubt about it.

If I had to describe the smell of mice, I would say a musty, urine type smell. Nasty, right?

To do this effectively, you will need to go through your house and clean up any evidence of mouse urine, and droppings.

Once you have completed this, you should be:

  • Used to the smell
  • Able to find fresh mouse urine

If you go a week or so without smelling any fresh urine, it is one of the signs that the mice have gone.

Flour or Talc on surfaces

One trick you can play is to scatter flour or talc around areas where you know that mice frequent regularly.

It is vital that you use non-scented talc! Mice have a very keen sense of smell, and they avoid anything new in the areas they use to travel.

Once you have scattered the flour or talc, check it each day for evidence of tiny footprints. If you have found and cleared away a mouse nest, you should be hitting that area with the powder!

If there are no footprints in the flour or talc after 1 week, hunt your home for other signs that the mice are all gone. This is a good sign on its own though!

Leave Traps

By leaving mouse traps in the best places, you can attack the mice problem, or help to confirm the mice have gone.

I recommended purchasing 2 or more of the best mouse traps for increased confidence of a successful capture.

Load all traps with some tasty mouse bait (again, to make sure you are successful) and wait. If you go a few weeks without catching any mice, it will give you a big indication that all of the mice have now left your house!

Awesome news, right?

Whilst we are on the subject of food… you probably noticed during the infestation that you had chewed up food items to contend with. Another sign that gives you some assurance that all mice are now gone is there are no more food items being chewed.

When All The Mice Are Gone, The Job Is Not Over

Simply getting rid of the mice does not mean the battle is over. Now, you need to keep them out!

When you have followed the signs above and you are confident that all the mice have gone, congratulations, you have moved past the first step!

Your next task is to ensure the mice do not come back again, but how do you do that?

  1. Seal all mice entry points
  2. Clean your house thoroughly – get rid of mouse urine odor
  3. Set up mouse traps in your attic and basement
  4. Get a cat (If you haven’t already!)
  5. Store food correctly
  6. Learn what mice can chew through

It is vital that you protect your house, the people who live there, and your belongings from future mice invasion!

Remember, when cleaning your home after a rodent infestation it is important that you are fully protected. Recommended gear includes:

I always wear these when tackling a rodent infestation. You need to consider your health at every step of the process.

Common questions regarding ensuring that mice are gone for good!

Can mice find their way back to my house?

Yes, a mouse can find its way back to your home if it does not travel far. You need to consider this when getting rid of a live mouse. You must take it far enough away from your home so it does not find its way back.

Do mice leave on their own?

Mice can leave of their own accord however, if a mouse has found its way into your home then it is there for a very good reason. It may have easy access to food (food is the biggest reason), or it may see your home as a safe environment to give birth in! The only reason mice would leave a warm place with a ready food source is if it feels threatened by a predator, or by you. If you want to get rid of mice, you need to be intimidating… or get a cat!

I saw droppings in my house but no mouse, does that mean it has left?

Not necessarily, no. The mouse (or mice) may simply be out looking for food or items for their nest. They might be back, so it is best to prepare for their arrival with some awesome new traps! Don’t forget some tasty mice bait too!
If you are in this situation, it is vital that you seal entry points. The mice may be back, and if you have found the entry point and have sealed it up, then it cannot get back in. Perform regular, and thorough checks around your property to make sure you are not too exposed.

Can mice just disappear?

Not in the sense that Houdini used to disappear, but they can leave your home for good if they stumble upon an environment they feel is better suited to their needs. Use this as an opportunity to seal all the mouse entry points and put some traps in all the right places.

The mice might be back! It is your job to make sure it cannot get back in.


There is no ONE sign that will 100% guarantee that all the mice are gone from your home. You need to check ALL the signs on this page before you can be 100% certain.

I said it earlier in this post and I will reiterate here, it is vital that you follow up on protecting your home when you confirm it is 100% rodent free. Knowing how to get rid of the mice is one thing, but it is up to you to ensure they can’t get back in.

Mice and other rodents can spread some very nasty diseases, and you will want to live in a safe, secure, and disease-free, infestation-free home, right?

DIY rodent control can be tricky, but it is certainly not impossible. I have been doing it for years and I have always had success, every time. It is a simple case of knowing your enemy and knowing how they get into your house. You can get rid of mice with knowledge, traps, peanut butter, and patience!

Good luck!
