Bats are native to North America and live in rural, urban, and suburban areas. They live in a variety of spaces, from rock crevices and caves to old buildings and bridges. Some bats, like red bats, live in trees.
If bats are flying around your yard, they are probably eating bugs.
There are 40 different species of bats in the U.S. that eat only bugs. One little brown bat may eat up to 500 bugs per hour.
As long as bats aren’t flying into your house, there is no reason to be concerned. Additionally, you don’t need to worry about bats flying into you. Bat echolocation is powerful - and contrary to popular belief, bats can also see fairly well - so they won’t fly into your hair or face.
If you are worried about bats roosting in nearby buildings, consider attaching a bat box to a tree or post to provide them a hideout.
