Modern bat houses featuring our advanced design and solid construction have proven successful across the United States. They are popular with people interested in low maintenance, environmentally friendly insect control. Others are searching for ways to house colonies which are presently conflicting with human needs. Of course, many folks are simply fascinated by these sophisticated creatures found right in their own backyard. Invented in Pennsylvania, these boxes are easily adaptable to other climates with proper coloration. Several sizes are available for any application.

Our design is based on over ten years of summer bat research and maintains an unparalleled 95% use record. (Source: PA Game Commission).
