The key to managing rodent problems is being able to identify whether you are dealing with mice or rats.

The Small and Silky Mice Characteristics
Biology of Rats vs Mice
Physical Characteristics
The house mouse is a small type of rodent that measures about 3 to 4 inches in length. Imagine the size of a grain of rice, that is roughly the size and shape of these species. They have a delicate, slender body and a long tail that is as long or longer than their body.
Their colour can be light brown, grey, or tan with a smooth appearance. Their ears are large and rounded, and their eyes are shiny and black.
Behaviour and Habitat
They prefer to live close to humans because they seek food sources like crumbs, grains, or stored food. They are excellent climbers and often find shelter behind furniture, in wall gaps, or in storage boxes.
They are highly active and reproduce quickly, they can reach sexual maturity as early as 6 weeks old. A single female mouse can have up to 10 - 12 pups in a litter, with 5 or more litters per year. Commonly seeking food and live indoors, mouse problems escalate fast if not controlled early.
Typical Food Sources
They are omnivorous, meaning they eat a variety of foods. This includes grains, cereals, pet food, and even plastic or paper if necessary. Because they prefer easily accessible food, they often end up contaminating stored items, leading to health hazards.
The Brown Rat (Rattus norvegicus) and Roof Rat (Rattus rattus)
Rats vs Mice, The Huge Difference
Physical Characteristics
- Brown rat (also called the Norway rat) is bigger, with a body length of 7 to 11 inches, not including the long tail. It has a stockier body, a broad head and a size and shape that makes it stronger.
- The roof rat is smaller, with a size of about 5 to 7 inches, but it has a long tail that is often hairy and smoother. They are long-tailed and sleek, a size and shape that allows them to climb easily.
Behaviour and Habitat
- Brown rats like rough vertical surfaces such as sewer pipes, walls or underground tunnels. They tend to live in burrows outside but can live in basements, storage rooms or sheds.
- Roof rats prefer to live high up in attics, trees or rooftops. They are excellent climbers and tend to seek food in higher areas.
Reproduction & Breeding Patterns
Both types of rats reach sexual maturity at about 3 to 4 months old and can produce up to 12 pups per litter. A female rat can have several litters per year, leading to rapid population growth.

Identifying Common Rodents, The Rats vs Mice
Knowing how to identify rats and mice involves looking at their size and shape, as well as their rat droppings and habits. Here are some key tips:
Size and Shape
- Mice are small, slender, with a long tail and slightly rounded ears. Their body length of about 3 to 4 inches long.
- Rats are larger, with bodies that can be 7 inches or more in length. They have a bigger head, thicker bodies and long tails that are often hairy or scaly.
Rat Droppings vs. Mouse Droppings
- Mouse droppings are tiny, about 1/8 inch long. Shape like small black grains, similar to a grain of rice, pointed at both ends.
- Rat droppings are much larger, about 1/2 inch long or more, with a capsule shape and blunt ends. Commonly scatter near food sources or on floors.
