Studies show the most successful bat houses are mounted on buildings or are free-standing. Our "Bat Tower" bat house mounts directly on a 4x4 post. The post becomes the landing platform, and from there the bats climb into the house. The four internal chambers and attic provide for multiple roosting opportunities. In addition, the side opens to for easy bat-viewing. (Picture shows house with door partially opened.) A highly valuable but misconstrued mammal, bats are essential for a healthy environment. Most species of North American bats are insectivores, eating from 3,000 - 7,000 insects nightly. Each of our bat houses is manufactured with a unique roughened surface which bats can easily cling to. The Eastern White Pine houses are solidly constructed for warmth, insulation and durability. Our bat houses are open at the bottom so they need no cleaning and birds will not nest in them. Over time the wood will darken and more naturally blend in with the environment. Hand crafted in the USA by Coveside.
