Echolocation is the use of sound waves and echoes to determine where objects are in space. Bats use echolocation to navigate and find food in the dark. To echolocate, bats send out sound waves from their mouth or nose. When the sound waves hit an object they produce echoes. The echo bounces off the object and returns to the bats ears. Bats listen to the echoes to figure out where the object is, how big it is, and its shape. Using echolocation, bats can detect objects as thin as a human hair in complete darkness. Echolocation allows bats to find insects the size of mosquitoes, which many bats like to eat.
Professional Little Brown Bat Control. 1  On the lookout: Before locating the roosts of the Little Brown bat, entrance and exit points must be found first. A professional will spend several days (usually at night when most bats leave the roost) observing the structure to identify where bats are coming and going. This will give them a good idea of where the roost is. Common entrances and exits are cracks, openings, or gaps in roofs, attics, or exterior walls. Tighten up: Depending on how the bat roost is handled, a professional will most likely set to work sealing up all entrance and exit points but one. One exit will be left for a bat valve or other exclusion device (so bats can come out but not get back in).
