Tree squirrels are the most common type of squirrel living across our Texas service area. As the name suggests, tree squirrels spend a lot of time in trees or other areas that allow them to be up off the ground. While harmless to people when living outside and away from our homes and businesses, squirrels that have adapted to living in urban and suburban areas have become a significant pest problem for home and business owners. Squirrels vary in appearance, but in general, have a long cylindrical body covered in light whitish-gray to dark reddish-brown fur and ears that stand up off the head. Their most notable feature is their long bushy tail.
