Keep reading to learn about a few signs of mice that you should watch out for in and around your house.

Small Droppings

This is due to the fact these small pests cannot help but leave evidence of their presence wherever they go. They typically leave behind these small pellets of feces that contain distinctive ridges. These droppings can help you identify where and how many mice have been in your home, as they tend to be left in large groups or piles.

Additionally, these droppings can also be a warning sign of the potential of a more serious infestation, as mice can spread numerous kinds of unwanted parasites and diseases throughout your home. As such, it is important to be aware of the droppings and take the necessary steps to get rid of any mice that might be present.

Shreds of Paper

Mice are constantly searching for new materials for nesting, and shredded paper provides them with the perfect nest-building material. When they search for food, they may also pick up bits of paper along the way. The shredded paper is easy for mice to manipulate and carry, and it may be the only material they can find in some cases.

Additionally, mice will also look for paper to help camouflage their nest site and the scent of their nest. The shredded paper makes for great insulation from both the cold and the hot. Mice have a strong connection with paper and use it to line pathways to their nests, create nesting areas, and store food.

These can be from discarded packaging, cardboard containers, boxes, or even small pieces of paper. Finally, by shredding paper, mice can create openings around their nest sites to gain easy access and avoid predators. Shreds of paper are a common sign of the presence of mice in your home.


Scratching is a common sign of mice in your home because it is an easy way for them to create tunnels and other hiding spots. Mice are good climbers, so when they are searching for food, they tend to climb up walls and use their claws to scratch the surface. They can also create scratching noises to alert other mice in the area.

The noise is a way of communication and may help them identify new sources of food. It also helps them to build nests and burrows. The sound can be very loud in confined areas such as a home and is an indication that mice are present. Mice can also cause damage to walls and wood as they create tracks and tunnels for themselves.

They may even be chewing on anything they can get their teeth into, such as wood or plastic. Mice can also create holes in your walls which can lead to further problems. Overall, scratching is a tell-tale sign of mice in the home, and it’s important to take measures to rid your house of these pests before they can cause further issues.


When injured or frightened, mice are known to make a high-pitched sound, which is why hearing squeaks indicates that mice have found their way inside. Mice are able to fit through the tiniest of openings, so it can be difficult to prevent them from entering your home. Mice not only spread germs and bacteria but can also cause significant damage to furniture and food packages.

This noise can be heard coming from walls, furniture, or any other area of the house where they may be hiding. Mice are prolific breeders, and if multiple mice are present in an area they will make squeaking noises at a higher decibel level than just one mouse. The noise can also be heard when they’re gnawing on stored food or looking for places to nest.

Once inside, they will continue to reproduce, making it even more difficult to get rid of them. It is important to take proactive measures in order to prevent mice from entering your home and to get rid of them if possible. Hearing squeaks is a sure sign that your home has become a haven for mice, so don’t wait to start taking action to get rid of them.

Scampering Noises

Mice are nocturnal animals, and during the night, they come out of their hiding spots in search of food and water. The noise they make running around is a sharp, quick, repetitive sound that is distinct. They also make a scratching sound as they move around in your walls, ceiling, and other areas of your home.

This noise is caused by their claws and teeth as they move along surfaces. When they scurry, they make a soft thumping sound as their feet hit the ground. If you hear scampering noises in your home, it’s highly likely that you have a mouse problem.

Additionally, because of their small size, they are difficult to spot and this is why scampering noises are a tell-tale sign that there are mice present. If you hear small scratching, scurrying, or squeaking noises, it is likely mice, and you should take immediate action to remove the infestation. To prevent further damage, it’s important to call this pest control company as soon as possible to address the mouse infestation.

Dark Brown Pellets

These pellets, also known as droppings, are a byproduct of the rodent’s diet. Mice often feed on grains and nuts, meaning their leftover waste comes in the form of small cylindrical or rod-shaped droppings. Since mice love to hide away in dark wall crevices, these droppings tend to accumulate in these areas.

Not only do these pellets become difficult to clean away, but they are also a replica of the size of the rodent carrying the droppings. A large amount of dark brown pellets often means there is a bigger-sized rodent lurking around in the home. As the presence of these droppings can be a strong indicator of a rodent infestation, it is important to inspect the area where the droppings are found as soon as possible.

Urine Trails

One of the main reasons for this is due to the mice leaving small droplets of liquid behind as they scurry along walls, behind furniture, and in other tight spots. These droplets are most likely caused by a combination of the mouse urinating as it moves as well as sweat or saliva from its body.

Additionally, mice will mark their pathways to identify areas they have visited and to share their scent with other mice, which also leads to the trails. Urine trails are one of the most tell-tale signs of rodents problem in your home, as they’re hard to miss and quite easy to spot.

By following the urine trails, you can quickly determine the entry points the mice are using, the possible food sources they are looking for, and any other areas of your home they might have been in. These trails are often found in the same general area as the rest of the mice droppings, further proving the presence of mice. Mice and their urine trails are a huge nuisance and health risk in the home, making it important to take care of the problem as soon as possible.

Strong Ammonia Smell

Mice in your home cause a strong ammonia smell because when mice inhabit an area, they tend to urinate in that area to mark their territory. When this urine mixes with the home’s dust, it creates ammonia. The stronger the ammonia smell, the more mice that are present in your home.

To efficiently remove the mice and also make the odor go away, it is necessary to remove all the accumulated urine and droppings from the mice. In addition, in order to prevent re-infestation, it is important to eliminate all potential entry points, such as holes, crevices, and cracks in the wall or baseboards.

If the smell persists, contact a pest management expert who can help you to exterminate the mice. By following these steps, you can ensure that you have rid your home of the awful ammonia smell that is the common sign of mice in your home.
