North America is home to many species of bats, which often roost in man-made buildings, and love the attics of homes. None of these animals are actually blind, but they do use echolocation in order to aid in navigation on the wing. They are all insectivorous, catching insects on the wing.
Only homes that are sealed up very tightly can avoid invasion from wild animal pests. All animals are humanely trapped and access points are sealed up properly. All work is guaranteed, and removal of animals is included. Please set up an evaluation as soon as the intruder is noticed.
