Common Mice In The Post Falls and Spokane Area

Did you know? Mice are incredibly flexible and can squeeze through openings as small as a 1/4 inch (about the size of a pencil) due to their ribcage being collapsible. This makes them great at getting into homes and hiding in tight spaces. Plus mice are excellent climbers and can scale vertical surfaces like walls, pipes, and even rough wood. They can jump up to 12 inches vertically and 36 inches horizontally, which allows them to easily navigate obstacles. This makes them extremely hard to keep out of homes.

  • Fit through small openings: Can squeeze through gaps as small as 1/4 inch.
  • Climbing ability: Can scale rough vertical surfaces and jump up to 12 inches.
  • Travel Routes: They can travel along horizontal wires and small ledges with ease.

Damage and Contamination:

  • Structural Damage: Gnawing and nest-building activities can damage insulation, wiring, and even appliances, leading to potential short-circuits, fires, or malfunctions.
