Provide a safe habitat for your local wildlife! According to Bat Conservation International, North American bats seek out loose tree bark and tree hollows to roost. This makes these poplar tree bark-clad bat houses the perfect natural nesting cavity! Built to last, our outdoors bat roosting boxes have been assembled by hand using high quality weather resistant materials, allowing it to withstand the elements while being mounted outdoors. Each bat box is handcrafted using reclaimed tree bark, rust proof exterior screws, pine lumber and exterior grade plywood. All joints are glued with non-toxic waterproof glue to eliminate drafts and create a dry interior. Handmade in Kentucky
