5 KEY FACTORS OF A GREAT BAT HOUSE
WORKING WITH MERLIN TUTTLE
There’s a reason we chose to work with Merlin Tuttle: He’s the best there is and he has a high bar for quality. Aside from his 60 years of experience working with and advocating for bats, Merlin also wrote the book on building bat houses. From the start, we worked with Merlin as we designed our bat houses, and we used his recommendations as our design constraints.
“Seeing well intended people disappointed by cheap, “imitation” bat houses troubles
me greatly. It gives good conservation a bad name. The BatBnB line of houses is the
first to be developed for mass sale that meets all my personal criteria. I have been
involved in the design and construction of these houses from the beginning and am
happy to endorse them as unsurpassed in meeting bat needs, resisting deterioration,
and still looking great.”
