Squirrels are the #1 animal we remove here at Advanced Wildlife Control with raccoons in a close second. These small furry animals with their bushy tails are abundant throughout Wisconsin. They are excellent climbers that can easily scale trees and buildings. Squirrels also love to eat nuts, acorns, pine cones, and seeds, especially bird seeds from your bird feeders. The most common squirrels in Wisconsin are the red squirrel, grey squirrel, flying squirrel, and the 13-lined ground squirrel.
