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. 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.

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


Mice in the attic can cause significant damage by gnawing the structure of the house, ruining insulation, and chewing on wires. They spread their feces and urine wherever they are active, contaminating food 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.


Although there are many commercially available mouse traps for homeowners to use in their own removal efforts, DIY attempts at mouse control often fail or even make the situation worse.
