Top 9 Signs You Have Mice In Your Attic

| | ,

You may be hearing some noises in your attic, or you may even be noticing a strange odor emanating from upstairs. these are signs that you have Mice in your attic, but what else do you look out for?

An attic is a perfect place for Mice to hide. For a start, it offers Mice warmth, bedding, and comfort. It also offers them a place where they can sleep without worrying about predators, AND gives them an excellent base to use while they travel your house looking for food.

But do not worry, it is very common to get Mice in your attic!

Let’s take a look at the rest of the signs.


9 Signs That You Have Mice In Your Attic


Scurrying Noises

Listening at wall
Listen for scurrying noises, especially in your attic, and walls. This is a sure sign that you have Mice!

Scurrying and scratching noises, especially in your walls and in your attic, are usually the first sign you have Mice in your home.

Mice like to travel in dark, confined spaces so they can avoid predators. Your cavity walls are the ideal place for Mice to use as routes through your home.

I remember the first time I heard scurrying noises in my cavity walls, I knew I had to investigate further!

When you hear noises and suspect that it might be a Mouse, the usual concerns creep into your head. Will the Mice jump into my bed while I am sleeping? Will they eat all of the sentimental items in my attic?

Will I even be able to sleep knowing that I have Mice in my attic!!


Mouse Droppings

Check your entire mouse for Mouse droppings, because if you have Mice, you will certainly have droppings!

This is usually the first thing that I check for if I suspect Mice infestation. I will prepare a survival kit for the attic and I will go and investigate further.

Take a powerful Flashlight, and ensure you have some strong gloves on. Check everywhere, even the places which are hard to reach, because that is where they are likely to have traveled.


Mouse Urine

Mouse urine will have a pungent smell!

Along with droppings, Mouse urine is another classic sign that you have Mice in your attic.

It is more of a challenge to hunt for Mouse urine because it is more difficult to see than droppings, but you can smell it.

If you are in your loft, and you have picked up a musty smell, it may be Mouse urine.


Chewed Items

Mice chew EVERYTHING to make a nest, keep an eye out for items that look as if they have been chewed!

Mice are in your home because they want a warm, comfortable, protective environment to set up a nest.

As soon as Mice enter your attic, they will look for a place to nest and will go looking for items they can use to build it. These items include paper, card, plastic, and pretty much anything that a Mouse can chew!

Mice will not care if they find a box of old, sentimental photographs. They will not care what they use, as long as it makes them comfortable.

Take a look around your attic to see if anything has been chewed. If you notice shredded paper, card, or anything else then it is possible you have a Mouse (or more) in your attic.


Odor

Mice infestation is accompanied by a stale smell!

I mentioned the musty smell that you can attribute to Mouse urine, and that smell tends to emanate through your attic.

It is a challenge to differentiate between the usual musty smell of an attic (caused by a collection of old items that you are storing) and the smell of a Mouse. When you visit your attic and you notice different smells, it can be a sign that you have a Mouse in there.


Live Mouse

It is obvious…if you see a live Mouse in your attic, then you have Mice in your attic!

Finding a live Mouse in your attic is a sure sign that you have Mice in your attic!

Yes, it is obvious, but it must be on this list.

Mice will try to avoid you at all costs, and if they hear you in the attic you can be sure that they will be in an area which is the most difficult to reach, well out of your view. Sometimes, you can catch them off guard though.

I remember entering an attic and the first thing I saw was a Mouse staring back at me. It was a stand-off! All I needed to do was move my arm an inch and it was off like a rocket. I had no chance of catching it!


Half-Eaten Food

Mice will hunt around your home for food, watch out for food, especially in your attic!

Mice enter your home for warmth, protection, and food.

Your home has food sources that a Mouse will sniff out in an instant!

If you do not store your food correctly, a Mouse will find a way into your home while you are sleeping, and will raid any area where they can smell food.

If you notice half ate food around your home, it is possible that the Mouse was disturbed while eating. A sure sign that you have Mice in your attic!


Increased Pet Activity

Pets will know that you have Mice before you do, so what out for them acting up!

A Cat is an awesome weapon in your fight to keep your home Rodent free!

The Mice will pick up on the Cats scent and may well avoid your home completely, especially if your Cat has the freedom to roam the entire perimeter of your home.

I was not the first to notice noise in my Attic, it was my Cat. He was acting very suspicious one evening and was spending a lot of time staring at the ceiling. At first, I thought he might just be interested in the intricate patterns near the lamp, but then I heard the scurrying.

A few hours later we were on the ground floor of my home and he rushed over to the wall for no apparent reason. Minutes later, I heard a scurrying noise in my cavity wall.

Keep an eye out for unusual pet behavior, because their sense of smell and sound are much better than yours. They will know that you have a Mouse in your attic before you do.


Holes In Your Home

Mice will make holes in your home to use for traveling, watch out for extra holes!

When Mice travel through your home, they need to create holes to ease access to other parts of your home.

Think of the classic Mousehole in Tom and Jerry…they do not always look like that, most of them are much smaller because they only need to be big enough to fit a Mouse head in.

Check everywhere around your home. The last thing you need if for the Mouse to find a way into your living area, because they will begin to hunt for food, and other items to chew on!

If you have new holes in your home, then it could be a sign that you have Mice in your attic.


Conclusion

Above are 9 of the most common signs that you have Mice in your attic.

The first thing you will probably do, is panic.

As soon as you get the panicking out of your system, it is time to do something about it!

The first thing you need to do is catch the Mouse. For that, you will need each of the following items:

  • Gloves
  • Dust Mask
  • Strong Bags
  • Cleaning Equipment

Think about the kind of Mouse trap you want to use, compare options such as traps v poison.

Improve your chances of catching a Mouse by using the best Mouse bait!

Then, once you have caught the Mouse, you will need to take steps to ensure your house is not accessible for Mice. It is a challenge, and it is very difficult to be 100% sure that a Mouse cannot get in. You can make it very difficult for a Mouse to enter your home.

When you think you may have Mice in your attic it is important to get rid of them ASAP. Mice droppings can carry some very nasty diseases, such as Hantavirus. For this reason, it is very important to go into your attic with a respirator mask on!

Good luck!

  1. It’s good that you mentioned how an unusual musty smell in your attic might mean that there are mice living inside. My wife and I were cleaning out our attic last week, and we noticed that there is a strange smell that is coming from the boxes in the corner of our attic. It might be a good idea for us to call a pest control specialist so that they can quickly find the source of the problem.
