Mount your bat house correctly so there's
a better chance it will be occupied.
In general, bat houses should be:
||Attached at least 15 feet high on
the side of your house, on an
outbuilding, on the garage, or on
a tall pole. You may be tempted
to place a bat house on a tall
tree, but studies have shown that
a bat house placed on a tall tree
is less likely to be occupied.
||Free from obstructions with at
least 20 feet of open space to
allow bats to pinpoint the house
and easily fly in and out.
||Warm. Bats like warmth, so make
sure your bat house is placed
where it will absorb warmth. The
best solution is to make sure
the front of the house is facing
southeast to expose it to sunlight.
||Northern states: keep in mind that
bat houses need to receive at least
6 to 8 hours of direct sunlight. You
may wish to paint the house black to
absorb plenty of heat (use a waterbased,
nontoxic, latex paint).
||Southern states: place the unpainted
bat house in direct sun.
||Extreme southern states: paint the bat
house white to reflect the heat.
Occupation of Houses
According to the OBC, approximately half of all
bat houses are occupied within the first summer
and about 80% are occupied within the first
2-3 years. Change the house's location if you
do not have a colony by the end of the third
year. You may also want to provide several bat
houses so bats can choose where they live.
Bats return from migration and awaken
from hibernation as early as March in most
of the U.S. and are abundant throughout
the summer and into early fall.
Attracting bats is a great, pesticide-free
way to help the environment, perpetuate
Nature's life cycle, and enjoy your
pond or backyard with less annoying,
biting mosquitoes. Don't be fooled by
old wives' tales – bats are great!
