Mice can enter your home and occupy space without ever hearing them. While they’d much rather live in total secrecy, mice make their presence known by damaging your home and leaving trails of droppings, urine and crumbs everywhere they go. In this article, learn how to control mice and learn what to be aware of when mice are found in your home.

The Most Common Type of Mouse Found In Most Canadian Homes

House Mice

The most common type of mouse found in Canada are House Mice. With adults growing as long as 20cm (8 inches), their tail makes up for half of that length. Some own House Mice as pets when purchased from the pet store although wild House Mice should not be interacted with as there is a high chance that they carry diseases that can be brought into your home and affect your health over a short period of time.

Not to be mistaken with common household pets like gerbils or hamsters, House Mice have pointed noses and protruding eyes with ears that are significantly larger and more round than that of a gerbil or a hamster. House Mice are likely to be seen during the colder months of the year as they go searching for warmer places to burrow, such as your home. Mice would much rather not be seen despite them being notorious for leaving a trail of food crumbs, droppings and urine as they scavenge for their next meal.

Home Damage

In their pursuit for food and shelter, mice are notorious for damaging your home by chewing and gnawing on anything at their eye level such as cables, baseboards, furniture and the wooden foundation of homes. Wires and electrical cables are common to be chewed on by mice during an infestation and can lead to significant damage to your home that can cause fires and other electrical complications.


Mice may be cute, but their droppings, urine, saliva and fur can carry extremely dangerous pathogens that can poorly affect the overall condition of your home. It has yet to be proven that wild House Mice can carry harmful diseases like other species of rodents found in Canada, although it is possible that mice can still bring diseases into your home due to their unsanitary living conditions.

Despite House Mice also being owned as pets, wild House Mice are born and raised in much different and unsanitary conditions as House Mice bred in a pet store. The poor living conditions that wild House Mice can thrive in are much different than the living conditions of pet House Mice that are safe from disease and interaction with other rodents and pests.

Here is a list of the common types of diseases that mice are known to carry into your home:

  • Leptospirosis
  • Lymphocytic Choriomeningitis
  • Typhus
  • Lyme Disease
