There is no fee to participate in this program. Bat Conservation International and numerous volunteer Research Associates in the North American Bat House Research Project have conducted years of research to determine which criteria are important for successful bat houses. Research has shown that tall and wide designs offer greater temperature diversity, a key factor in attracting bats. Proper crevice widths, roughened interior and landing areas, ventilation slots, and tight, draft-free construction, are also extremely important. Additionally, information must be enclosed with each bat house sold concerning correct placement, sun exposure, painting, and habitat.
Correct instructions are just as important as having a good design.
Manufacturers who wish to earn this Bat Approved certification must submit a prototype or finished bat house to BCI for evaluation. Bat houses will be reviewed according to the guidelines below, and will be scored on an approve or disapprove basis. Manufacturers will be provided with a copy of the evaluation and comments. Designs not meeting BCI s approval must be resubmitted, after the appropriate changes have been made in order to gain certification. The Bat Approved certification will be granted for a two-year period, contingent on maintenance of the approved design and quality standards.
