One of Missoula’s most common wildlife in city limits is the Eastern Fox Squirrel. It is the largest squirrel in North America and is an invasive species. It is distinguishable by its greyish coat with a reddish underside. This squirrel has displaced our native squirrel populations, preys on our native bird species and can be quite a difficult pest problem to tackle once they get in our homes. People generally notice they have squirrels in their home during their breeding season when the young pups are old enough to run around.

There are many other nuisance wildlife that can become pest issues, such as birds, native squirrels and pack rats.
