How to Identify a House Mouse (mus musculus)

Identifying a house mouse (mus musculus) is relatively straightforward. This species of mouse is a small, greyish-brown mammal with a pointed nose, large ears, and small eyes. Mouse tail is just as long as the body, and is usually scaly.

The house mouse is usually around 6-10 cm in length, and weighs between 10-20 grams. They are agile climbers and can jump up to a foot in height. This rodents generally have four toes on each front foot and five on each hind foot.

The house mouse also has distinctive markings, such as white feet and a white belly. The fur is typically a mottled greyish-brown colour that may vary in shade depending on the individual mouse.

When observing a house mouse, it is important to look out for signs of infestation. These include droppings, which can be distinguished from other rodent droppings by their small size and shape, as well as gnaw marks on food containers or other objects. Additionally, the smell of urine may be present in areas where house mice have been present.

How to prevent house mice from invading?

There are several steps that can be taken to prevent house mice from invading. 

  1. Seal entry points – Every mouse can enter a home through even the tiniest of openings, so it is important to inspect the exterior of the home and seal any cracks, crevices, or gaps that may exist. Caulk and steel wool can be used to fill in these areas.
  1. Remove food sources – Mice are attracted to food sources, so it is important to keep food and garbage stored in tightly sealed containers. Pet food should also be stored in secure containers, and any spills should be cleaned up immediately.
  1. Trim vegetation – Often mice can use tall grass and bushes as hiding places, so it is important to keep vegetation trimmed and away from the home.
  1. Clean up debris – Mice are also attracted to items that provide shelter, such as piles of firewood or cardboard boxes. It is important to keep the area around the home free from these types of items.
