Mice and Rodents · MetroWest Massachusetts
Heard something overhead? Start by documenting what you are noticing.
Sounds, droppings, gnaw marks, and disturbed insulation can come from mice, from other animals, or from non-pest household conditions. Where the evidence appears and how it repeats matters more than any single sighting.
What are you noticing?
- Scratching, scurrying, or gnawing sounds overhead or inside a wall
- Small dark droppings along edges, in drawers, or near appliances
- Gnaw marks on packaging, wood, wiring, or stored belongings
- Insulation that looks flattened, tunneled, or gathered into a pile
- Shredded paper, fabric, or nesting-like material
- Greasy smudge marks or worn paths along framing
- A smell that was not there before
Heavier thumping, slow dragging, or daytime activity may point to something other than mice. Record what you hear rather than assuming a cause.
Where rodent activity commonly appears
Homeowners usually notice activity where food, shelter, warmth, or a protected route into the structure come together.
- Attics and insulation
- Wall and ceiling cavities
- Kitchens and pantries
- Basements and crawlspaces
- Garages and storage areas
- Utility penetrations and sill areas
- Roof edges, soffits, and vents
- Wood piles or dense ground cover against the foundation
What else could you be hearing or seeing?
Other animals, HVAC equipment, settling framing, branches on the roof, and wind can all create overhead sound. Droppings and damage can also overlap between species. Photographs and dated notes help a professional narrow the possibilities.

When may an inspection be appropriate?
Consider requesting an inspection when activity continues or increases, evidence appears in more than one area, wiring or ductwork looks damaged, you cannot safely see the affected space, or you are unsure what kind of animal is involved.
