After Mississippi brothers Jerry and Larry Glass tired of building homes for humans, they started making houses for smaller creatures, and HEARTWOOD was born. Their handcrafted Bat Lodge keeps at least 40 flying mammals cozy and dry in two chambers. Its body is made from rot-resistant wood rescued from scrap heaps, and the roof is Forest Stewardship Council-certified cypress. This little haven comes in an upcycled box, padded with salvaged paper. $53, planetnatural.com

Then open its back door to insert twigs as perches. Watch for new residents within a few weeks. $20, gardeners.com
