Why Homeowners Find Field Mice in Attics

Deer mice and white-footed mice, commonly lumped together under the catch-all term field mice, are small rodents typically found outdoors. However, their need for food and shelter can lead them into homes.

As development encroaches on open lands and yearly harvests in adjacent agricultural lands occurs, it destroys the natural habitat of many field mice.

In attic and wall spaces, the creatures often find an impromptu replacement for their outdoor dwellings.

Small Size, Easy Entrance

Field mice are small, only five and a half to eight inches long including their tails, which can be half their body length.

This diminutive size allows them to easily work their way into tiny crevices and openings.

Early warning signs of a field mouse in the attic include:

  • Squealing and squeaking noises
  • Scratching
  • Scurrying
  • Chewing

Diseases and Other Problems

The sounds of field mice in the attic are unsettling to homeowners.

Their chewing can short out wires and create the potential for fires. The animals also leave droppings and urine and contaminate kitchens and food.

Rodents can host dozens of diseases transmittable to humans. Deer mice are notorious for carrying Hantavirus, which can be deadly to people.

Other unwelcome maladies include:

  • Salmonellosis
  • Rat-bite fever
  • Leptospirosis
  • Lyme disease
  • Tapeworms

When there is a field mouse in the attic, all these potential problems come home to roost.

Prevention Efforts

To stop field mice from getting in attics, the full perimeter of a structure must be rodent-proofed.

This involves carefully surveying exterior walls, doors, windows, and the foundation and roof.

Any gap larger than a quarter of an inch must be covered or plugged. Sheet metal, steel mesh, or steel wool mixed with caulk are the preferred materials.
