Bat Noises | What Sounds Do Bats Make? | Critter Control

 

Bats make sounds that are two or three times higher than humans can hear. When the flying mammals use echolocation, humans are only sometimes able to make out very quiet clicks. Slowed down, the clicks are actually chirping with a distinct tonal progression. Though bat sounds are nearly impossible to hear outdoors, the noises of echolocation can be detected inside insulated homes. Additionally, residents may hear scratching and flapping sounds made by bats trapped inside attics or other areas of the home. https://www.crittercontrol.com/wildlife/bats
