You can sense victory…the war is over, or so you think!

But, how can you be sure that all the mice are now gone? How do you know if your safe from all the diseases that mice can bring to your home?

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!

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?

Let’s have a look at the things you can do to know, 100%, that all the mice have gone and you can return to normality.

How Do You Know When All The Mice Are Gone?

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.

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.

Check For Nests

It is time to go on a hunt for mouse nests!

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

When you are sure there is a mouse in your home, you should always pick up any mouse 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 mouse droppings, indicating the mouse is still around!

Always ensure that you clean the area thoroughly too.

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

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 home.


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 home and clear 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 uring

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

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.

Load all mouse traps with some tasty mouse bait 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 home! Top news, right?

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

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.

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 good reason. It may have easy access to food, or it may see your home as a safe environment to give birth in!

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!

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 mouse traps in all the right places.


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% mouse free.

Good luck!

  1. I found mice droppings in my spare bedroom(I kept extra food stored there. Cartons and cans that I didn’t need at the moment. Like an extra pantry.)
    This was on a Friday. I caught several in a no-kill trap, but decided to tear the room apart and find where they were coming in. Tuesday morning we cleaned and searched and found a nice hole where the TV cable came in. We sealed it up, cleaned up and today is Friday.
    The room has showed no signs of any mice. But now I’m paranoid. I found, I think droppings in the corner of my bathroom. (Which is right beside the spare room.) I think they were old droppings, but I set up the trap again just in case. But is has been 3 days. What do you think? ( I’ve been very upset and sick over this whole thing.)

    • Hi Jackie

      I am sorry to hear that you are having issues with mice, and completely understand the upset this is causing you. Rooms that are less frequented by us humans is a common target for mice, especially if there is food in there.

      The good news is, it sounds like you are conscious of the holes in which mice can squeeze through. You sealed up the cable hole, that is a huge step towards having a mice free home.

      What would I do next? Here is my list:

      1. Check around your home for other common entry points for mice.
      2. Thoroughly check each room for mice activity, and clean it up (droppings, urine, gnawed items). Make a note of what you found and where. This will allow you to re-check these areas each day.
      3. Listen. If you can, try to remain at quiet as you can for a few hours each night before bed. Mice are small, but they can be loud when they are traveling around your home.
      4. Re-check your home every day to see if you can identify any mice activity.
      5. Leave the trap in your bathroom for at least 1 week.
      6. Clean food items out of the spare room if you haven’t already

      Good Luck!

  2. I have recently been seeing small mice running from room to room upstairs in my house. I have gotten rid of 1 of them but there are still more. I don’t know how many but I have put rat poison in many rooms and mice traps. Im also worried my dogs might get harrmed by the mice and if so how could they get harrmed and how can u suggest to get rid of these mice.

    • Hi John

      Thanks for getting in touch!

      Firstly, I am sorry to hear that you are having some issues with mice.

      Secondly, I would not be using poison if I had an animal. There is a small chance that your dog could ingest some of the poison. I would be using something like the Victor tin cat mouse trap to catch the mice. It has the ability to catch multiple mice, and your dog will struggle to get into it.

      There are some other pet safe mouse traps you can consider too.

      Re recap:
      1. Use the Victor Tin Cat trap
      2. Load it up with some mouse bait food
      3. Stop using poison
      4. Check the trap every few days

      It will take some time, but even after a few days, you should notice a positive difference.

      In terms of harm to your dogs, there are some diseases/parasites that can be transmitted from rodents to dogs or even humans. The good news is that the mice will want naturally to keep away from your dogs. Just ensure that you clean up any feces or mice urine to reduce the chances of picking up an illness.

      Good luck!
