Bats in the Attic

Bats in the Attic:  As a naturalist it is hard remove an animal from where it wants to be.  Several years ago the bats moved into my attic but now their numbers have increased to nearly 30, and with that increased number comes an increase in the amount of bat guano and its associated smell. It is time to move the bats. To keep the bats from losing a home I have simply created a new one for them.  I managed to build a bat box that fits snuggly over the hole through which the bats leave my attic on their nightly excursions.   To leave my attic the bats must depart through their traditional entrance and pass through my bat house to reach the freedom of the evening skies. This way they will get used to the box on their way out. I managed to place an old sock over their entrance hole with the toe cut out of it. It allows the bats to squeeze their way out of their entrance hole  into and out of the sock but upon their passing through the hole in the toe of the sock the hole closes behind them and they will be unable to get back into my attic.   I will still have my beloved bats but without the guano and the associated smell in my attic.
