Bat Facts

"Blind as a bat."

Bats not only "see" the world with echolocation, but they have good eyesight. Some bats find their food exclusively with sight and they can see better than humans in dim light.

"They get tangled in your hair."

Bats can be very curious. They will often circle around something or someone new in their air space to take a second look.

"Bats are flying mice."

Bats are actually more closely related to primates than to rodents. Most bats give birth to only one "pup" per year which they feed milk. Other than humans, bats are the longest lived mammals in North America; one little brown bat (Myotis lucifugus) is at least 34 years old.

"Bats are just pests."

Bats are important insect predators, pollinators, and seed dispersers. Bats live on all continents except Antarctica and are on the decline worldwide.

"All bats carry rabies."

Bats are not "carriers" of rabies; less than 1% of bats contracts rabies and dies. Bats will bite in self defense. Avoid handling them as well as other wildlife.
