Why are bat houses Bad?
Bad bat house designs are simply flawed from the start. They are often too small overall and contain crevices too large. Sometimes a critical detail is omitted, such as a landing plate. Usually these boxes cannot compete with a modern design, even after being upgraded by a creative hobbyist.
Do bats like cedar bat houses?
The Wisconsin Department of Natural Resources scientists recommend using cedar, for instance, as it is naturally resistant to changeable weather conditions: “The best wood to use to build your bat house is naturally weather resistant wood like cedar, rough-sawed black locust, white oak or old barn wood”.
Do bats like bat houses?
All available evidence suggests that most of America’s crevice-roosting bats prefer crevice widths of 3/4 to 1-1/2 inches when using open-bottomed houses. However, they also routinely use bat houses with a single 2-inch chamber and a 3/4-inch entry. The bats use the smaller crevices, leaving wasps to the wider spaces.
Will bat boxes attract bats?
Existing evidence strongly suggests that lures or attractants (including bat guano) will NOT attract bats to a bat house. Bat houses installed on buildings or poles are easier for bats to locate, have greater occupancy rates and are occupied two and a half times faster than those mounted on trees.

Obstructions in the form of branches and surrounding vegetation make it more difficult for bats to drop into flight.
Should I put a bat house in my backyard?
With populations of tree cavity roosting bat species like little and big brown bats in decline due to the effects of White Nose Syndrome and habitat loss, properly constructed and placed bat houses can be an important factor in assisting their survival.
How long does it take to attract bats to a bat house?
Be patient, and allow time for bats to discover and examine the house. If it’s still unused after two years, though, try modifying or moving it. According to BCI research, 90% of bat houses that attract bats do so within two years, while the other 10% take three to five years.
