| Because bats have
lost roosting sites and have been poisoned by
pesticides, their numbers have dwindled and some species
are endangered. Providing a home for them, not just as a
daytime hangout but to make them less vulnerable during
hibernation, is one way you can ensure their future. In
return, each Little Brown Bat, for instance, will
consume up to 600 mosquitoes in one hour.
Locate your bat house
near a permanent source of water (ideally within a mile
of a stream, lake or marsh), about 12 to 15 feet above
the ground on a building, tree or pole - a building will
offer the most stable temperature. In cooler parts of
the country, orient your bat house to get maximum
warmth, especially in the morning (southeast exposure).
In warm climates, bat houses should also receive morning
sun, but in hot climates they need mid-day shade. If
your bat house is not occupied by the end of the second
year, try moving it to a new location.
Use untreated,
rough-sided lumber and do not use paint as the odor may
repel bats. Bats need a rough surface for a secure
foothold. If rough-sawn lumber is not available, cut
1/16" horizontal grooves at 1/2" intervals.
