Bats are an essential part of our ecosystem. These nocturnal creatures can help with pollination and will eat up mosquitoes and other pesky bugs from your yard. Therefore, bats are beneficial animals to have around your house but are problematic when they find their way into people’s homes. A colony of bats can range in size from 1 bat to up to 5,000 bats. They are creatures of habit so they will return to the same place year after year such as your attic spaces to hibernate.
Bats have a very high metabolism which causes them to get cold very easily. So they often seek out areas of high heat like attics. Attics are a popular place for bats to live because they offer a warm, dry, and safe place to stay and raise young. Bats are more active in late spring and summer of Wisconsin and will usually migrate to warmer climates in the colder months. However, they can sometimes be found hibernating in the warm attics of people’s homes as well during the winter months.
