The deer mouse rarely invades homes, and is found in rural areas.
The house mouse is the most common rodent pest in most parts of the world. It can breed rapidly and adapt quickly to changing conditions.
These rats have smaller eyes and ears and shorter tails.
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.
Tree squirrels get their common name from the fact that they are found only in areas where there are trees. There are three representative species of tree squirrels: fox squirrels, gray squirrels and pine squirrels.
