How Do I Keep Mice Out of a Garage?

By the Omaha Pest Control team · Updated 2026-10-21

Short answer

Replace worn door seals, seal gaps around utility lines and the slab edge, store bird seed and pet food in sealed bins, keep items off the floor and keep the area around the garage free of clutter and tall grass.

Seal first

  • Install a full length door sweep on the garage door
  • Fill gaps around pipes, outlets and cables
  • Check the corner where the door meets the slab
  • Cover vents with quarter inch hardware cloth

Remove the draw

Seed, pet food, cardboard and fabric make food and nests. Use hard plastic bins and shelves.

Monitor

Place snap traps along the walls and check them regularly. Droppings are an early warning.
