Quick Facts About Mice

  • House mice are one of the most common pests in homes, cottages, and businesses across Ontario.

  • They can enter through tiny gaps as small as 6 mm and breed rapidly indoors.

  • Mice contaminate food, chew wires, damage insulation, and spread harmful bacteria.

  • They’re most active at night and often nest in walls, attics, basements, or storage areas

Common Signs of a Mouse Problem

  • Droppings (small, dark pellets) found along walls, in cupboards, or near food.

  • Scratching or gnawing sounds in walls or ceilings, especially at night.

  • Chewed food packaging, insulation, or wires.

  • Small tracks or smudge marks along baseboards or entry points.

Prevention Tips

  • Seal all exterior gaps, vents, and holes larger than 1/4 inch.

  • Store food in airtight containers and clean up crumbs or spills promptly.

  • Reduce clutter indoors and outdoors where mice may hide or nest.

  • Keep garbage bins tightly sealed and away from entry points.
