Harmless and highly beneficial insect eaters. If spotted roosting in trees, maintain a respectful distance of 5+ feet to avoid disturbing them.

If bitten or scratched, wash the area thoroughly with soap and water and seek immediate medical attention.

The eastern red bat ( Lasiurus borealis ) is a species of bat in the family Vespertilionidae. Eastern red bats are widespread across eastern North America, with additional records in Bermuda. They are also present, though rare, throughout many of the Bahamian islands. The eastern red bat is closely related to the desert red bat ( Lasiurus blossevillii ); the two species are sometimes collectively referred to simply as red bats .
