Mice will go into any type of home or building that has access points for them, including cracks and crevices, vents, and holes. They prefer warm, dark, and sheltered areas, such as wall cavities, attics, basements, and storage sheds.

Mice are drawn to attics as a source of warmth, shelter, and food. Mice also like to build nests in the insulation, cardboard boxes, and other soft materials, making the attic a perfect habitat.

They often enter homes through small holes no bigger than a dime. Eaves, cracks in the exterior walls, vents along the roofline, and utility access points are easy to access entry points.

In most cases, mice are nocturnal, which means they usually remain in their nest during the day. A mouse can venture out at night to search for food.

If a mouse has been disturbed and feels uncertain or threatened, it may move out of the attic during the day.

Signs of Mice in the Attic

Homeowners can tell if there are mice in the attic by paying attention to certain sights, sounds, and smells.

The sounds of pattering feet and scurrying, rustling sounds as they move inside walls, and small squeaking noises in the attic can also indicate the presence of a mouse infestation. The smell caused by mouse droppings, as well as their distinct musky odor, can be olfactory clues to mice in the attic.

Visual cues include mouse tracks, small brown droppings, urine stains, greasy smudge marks, wood shavings from gnawing, and mouse nests woven together from shredded fibers.

A mouse will typically build its nest by first collecting soft material such as grass, feathers, and shredded paper to create bedding. The material is then formed into a loose ball and placed in an area that is safe, such as in a corner of a room, behind furniture, or in a garage. The mouse will then gather more material to reinforce the exterior, often using pieces of cloth, string, or leather to construct a thick wall. Finally, the nest is typically made waterproof by using small amounts of mud or saliva and may be lined with fur or other soft material for added warmth.

Mouse Damage in the Attic

Mice in the attic can cause significant damage by gnawing the structure of the house, ruining insulation, and chewing on electrical wires.

There are health risks with a mouse infestation. They spread their feces and urine wherever they are active. Mouse droppings and urine will soil attic insulation. They will contaminate food sources and water sources with harmful diseases such as tularemia, leptospirosis, Hantavirus, and salmonellosis. Their presence also brings additional pests, such as fleas and ticks, into the home.
