When The Cat's Away, The Mice Come To Play

A Guide to this Seasons Unwanted Visitors

Although rodents are year round invaders, the fall and winter seasons is when Americans normally experience a rise in these unwelcome visitors setting up camp in their homes. As a part of Rodent Awareness Week, which is Oct 21-28th, we hope this guide to different types of rodents you can find in your home these holiday season helps.

Here are the most common rodents you will find this holiday season in the pacific northwest:

1. Roof Rats - also known as a black rat, these are one of the most common type of furry invaders one may find in their home. Black to light brown in color, these omnivores are a plague to farmers crops, and can get up to 18.25 cm (or 7.2 in) long. These rodents prefer to nest in roofs and other high places, and can be found to form dens with many others. 

2. Norway Rats - also known as a brown rat, is the most common rat to be found inside your home. While their smaller siblings, the black rat prefers high spaces, the Norway rat prefers to burrow under buildings and hide in basements and dark spaces. The Norway Rat is also one of the largest of its species, growing to up to 28 cm (or 11 in) in body length alone, with a tail almost as long. Fun fact, although the Brown Rat is named after the country of Norway, they actually originated in China, and spread from there to become the most successful mammal on Earth, second only to humans. 

3. House Mice - also known as the field mouse, are typically a wild animal, but they have begun to thrive greatly due to the increase in the human population. It is now much harder to find this form of mouse in the wild, as they have begun to reproduce in heavily populated areas. These small mammals can be identified by their pointed snout, large round ears, and long hairy tail. They generally only get to be about 10 cm ( 3.9 in) long from snout to base of tail, with a tail length of 10 cm (3.9 in). Mostly found at night, these creatures prefer dark spaces such as the spaces in walls. These invaders are pack animals and build nests of soft materials, with one dominant male surround by many females.
