Deer Mice

Pest Facts: Deer Mice

Description

The deer mouse rarely invades homes, and is found in rural areas.deer_mice

Color: Brown, with white feet and underbelly
Legs: Four
Shape: Round
Size: 5 to 8 inches long

The deer mouse prefers the outdoors.

Habitat
The deer mouse makes its home outdoors in sheltered areas such as hollow tree logs or piles of debris. On the rare occasions the deer mouse comes indoors, it prefers undisturbed areas such as attics.

Threats
The deer mouse transmits the potentially fatal Hantavirus Pulmonary Syndrome. The disease can be transmitted through contact with mouse carcasses, or by breathing in aerosolized urine droplets of infected deer mice.

Prevention
To keep mice and other rodents out, make sure all holes of larger diameter than a pencil are sealed. Mice can squeeze through spaces as small as a nickel. Seal any cracks and voids. Don’t overlook proper drainage at the foundation and always install gutters or diverts which will channel water away from the building. Use heavy gloves and protective breathing gear when working in an area populated by deer mice.

Roof Rat – Rattus rattus

Color: Blackroofrat, Grey or Brown
Legs: Four
Shape: Long
Size: 16 inches total (6-8″ body plus 6-8″ tail)

Description
Roof rats get their name from their tendency to be found in the upper parts of buildings. Ranging in size from 6 to 8 inches in length, not including their tails, they have very poor vision and are color blind. They do have extremely strong senses of hearing, smell, touch and taste.

Habits
Roof rats are known for the damage they cause by chewing on materials and eating stored foods.

Habitat
Roof rats can be found in the upper parts of buildings, and can also be found under, in and around structures. They only need a space of one-half inch to get into buildings.

Threats
Roof rats secured their place in history by spreading the highly dangerous bubonic plague. They support many ectoparasites and urinate on food.

Prevention
To prevent rats from entering a home, seal up any holes or cracks larger than a quarter. Remove sources of moisture and harborage.

Rats often destroy insulation value with their tunneling and chewing of vapour barriers.

We also provide solutions for rodent clean up and insulation removal.  Often times we find insulation that is badly contaminated with rodent droppings and urine.  When we remove insulation it often uncovers locations where rodents are gaining access.  To find out more or to request a quote please Contact Us
