Mice can be distinguished from young rats by their small eyes and legs. They weigh between 30 g and 45 g, their bodies are between 6 cm and 9 cm long, and they have large ears. Their tails are almost as long as their bodies. Their fur is gray, and their stomach is lighter in colour.

Development and Behaviours

Female mice have litters of six to eight babies and can have up to eight litters over their life cycle. These small rodents usually live less than one year. All five of their senses are very developed. They are curious by nature, and they often end up making messes anywhere they go. They snack about twenty times a day on small quantities of food that they can find just about anywhere. They especially feed at night and are most active at night. Inside buildings, mice generally settle in attics. Everything within a 4.5 m (15 foot) radius of their nest is considered to be their territory.


  • Trim lawns as short as possible and remove likely locations for nesting by removing anything encumbering the building’s surroundings.
  • Ensure that all trash is in containers with tight-fitting covers.
  • Eliminate water sources such as leaky faucets, pipes with condensation on them, and open-air drains.
  • Keep your kitchen clean and ensure that your pet’s food is in properly-closed metal or glass containers.
  • Block all possible openings, especially those which are near the ground, because mice can enter through openings as small as 0.6 cm (¼ inch) wide.
