Roost Mitigation

Laura Finn, the founder of Fly By Night, Inc., conducted extensive research on the roosting preferences of bats and their use of bat houses for her Masters Thesis at the University of Central Florida (1993-1997).  The project was supported by Bat Conservation International and involved the comparison of temperatures in a variety of bat house designs and occupied building roosts. These studies were necessary because safe alternate roost sites are vital to mitigate for the decline of natural habitat and the increasing loss of roost sites .   The information on this site is based on twenty years of experience, long term research and direct observation that continues to highlight that bats NEED bat houses and the importance of our continued bat house research.

Fly By Night Bat Houses Are:   

·     certified 'Bat Approved' by Bat Conservation International


·          constructed of pine exterior and plywood interior      


·          held together with galvanized screws for added strength


·          all joints & seams are sealed with high quality caulking to exclude moisture and light


·          all exterior and interior surfaces are painted, stained and / or varnished (3 or more coats)  to seal and protect the wood from            moisture, to enhance solar warming and to protect bats from any chemical timber treatment

                       *** BCI research shows that caulked and painted bat houses are more likely to be occupied than bare wood bat houses


·          equipped with an attic to provide horizontal roosting surfaces preferred by some species (i.e. evening bats)


· equipped with exterior ventilation slots to prevent over heating and interior slots that allow easy access between chambers and into the attic


·          Interior roosting substrate is created rather than added— interior pine surfaces are manually grooved and plywood partitions are     roughened with a wire wheel

                       **Screen is NOT used — our research revealed significant problems caused by screen failure. We caution against attaching any materials.    


·          larger than most ‘garden center’ bat houses commonly available, research shows bats prefer larger bat houses


·          composed of three or more interior chambers and a 6 inch landing pad

                       **Additional chambers provide bats the needed variety of thermal conditions & landing pads make it easy for bats to enter
