The BCI (bat conservation international) is a establishment built around making housing for bats. One of the main reasons people like to attract bats to the area around their homes is to cut down and possibly eliminate the mosquito colonies built around them in holes and trees. A bat house must be at least 25 inches tall or more if you really want to put the extra work into it. Bat houses are a great essential to have because mosquitos have become out of control in a lot of habitats. Bats will not necessarily house in your bat house just because you put guano inside or around the bat house. It is best to mount a bat house on a pole or on the top of a building because the bat houses placed on trees are not as noticeable by the bats. They love to get into crevices to house themselves and raise their young, with a bat house on a tree it is harder for the bats to detect it. The temperature required for the bats to have a comfortable housing are is anywhere between the degrees of 80 and 100 degrees. The best mounting spot for a bat house that attracts bachelor bats is on a brick structure or on a wooden structure; these bats are the easiest to please. However, if you are wanting to attract a little brown bat then the temperature of the bat house needs to be at or closely around 100 degrees F. If you are wanting to attract a big brown bat then you need the temperature to be at 95 degrees F. These are a few useful tips on how to properly manage a bat house and attract them I hope it helps you as much as it helped me. This in turn will help rid your home of nasty mosquito’s.
