Mice Nest 101: Where, How to Find Tips – A Comprehensive Guide

Mice enter your home to find food and water or to escape the cold weather. When they move into your house, they begin to settle in and build their nests.

So, where and how do you find mice nests in your home? Mice are clever in their nesting preferences, preferring attics, basements, wall voids, and crawl spaces as safe havens. Look for scratching noises within the walls, droppings in hidden corners, and a faint musky scent lingering in hidden spaces to find the mice nests. 

This post is for you if you want to know how to find mice nests, where to look for them, and what to do once you find them. We will also go over how to keep mice out of your home and how to get rid of them permanently.

How Do Mice Nests Look Like?

How Do Mice Nests Look Like

In cluttered spaces, you may find it challenging to differentiate a mouse’s nest from ordinary debris. However, there are several key characteristics of a mouse nest. They include:

Structure and Shape: 

Mice nests have a well-defined and compact structure. They often resemble small, spherical balls with an entrance point, providing a cozy and secure shelter for the inhabitants. 

Unlike random debris, which may appear haphazardly scattered, mice nests have a more organized and deliberate arrangement of materials.

Materials Used: 

Pay close attention to the materials used in the construction of the nest. The presence of shredded paper, bits of cloth, or chewed insulation is a strong indicator of a mouse nest.


Mice prefer concealed and secluded spots for their nests. Therefore, look for nests tucked away in hidden corners, crevices, or behind furniture. 

Activity Traces: 

An active nest will show signs of life. Look for fresh droppings or evidence of gnawing near the nest site. The presence of these signs indicates that the nest is currently occupied and actively used by mice.

Where And How Do I Find Mice Nests?

Now that you know what mice nests look like. Let’s look at the most common places mice nests are found in our homes and how to find them.

Where And How Do I Find Mice Nests

1. Attics and Basements: 

As mentioned, mice prefer undisturbed areas with little human activity, making attics and basements ideal nesting locations. Look for signs of nesting materials in corners, crevices, and tucked-away spaces in these areas.

2. Wall Voids: 

The space between walls is an excellent hiding place for mice’s nests. If you hear scratching sounds within walls or detect a faint odor, this could indicate the presence of a hidden nest.

3. Under Appliances: 

Mice may build nests beneath appliances such as refrigerators, stoves, or washing machines because these areas provide warmth and protection.

4. Storage Boxes and Cluttered Areas: 

Cardboard boxes, especially those left undisturbed for a long time, can be inviting nesting spots for mice. Cluttered areas in garages, closets, and storage rooms also offer concealed spaces for nests.

5. Insulation: 

Mice also build nests within insulation material. This makes detection a bit challenging. Look for signs of disturbed or shredded insulation in areas like attics and crawl spaces. Also, if the attic has a musty smell of ammonia, it may indicate a mice infestation. The ammonia smell is due to mice excretion.

6. Outdoor Areas: 

Besides indoor nesting, mice may construct outdoor nests in protected areas around your home. Check for nests in shrubs, bushes, woodpiles, and other secluded spots.

7. Behind Furniture: 

Mice may build nests behind or beneath furniture, especially if it is rarely moved or cleaned.

Tips For Detecting Hidden Nests

  • Thermal imaging cameras: These cameras detect temperature variations. This allows you to identify potential nesting areas where mice generate heat. These cameras can reveal hidden spots where mice may have built their nests, even behind walls or in ceiling voids.
  • Motion-activated cameras: Strategically place these cameras in areas suspected of harboring mice nests. These cameras will capture images or videos of any movement, providing concrete evidence of the mice’s presence.
  • Look for Fresh Nesting Materials: Mice continuously collect materials to build and maintain their nests. Keep an eye out for freshly gnawed items, such as paper, cloth, or insulation. 
  • Follow Their Trails: Mice will create well-worn pathways through your home as they move between their nests and food sources. You can follow these paths to identify potential nesting areas nearby.
  • Observe Nighttime Activity: Mice tend to be most active during the night. Consider staying up late and quietly observing areas where you suspect nesting activity. You might catch glimpses of mice moving to and from their nests.
  • Use Bait Stations: Set up bait stations with enticing food to lure mice out of their nests. Once they take the bait, they may lead you back to their nesting sites.
