Why attract bats?
Although often maligned, bats are actually an important ally for gardeners. They are the primary predators of night-flying insects, including moths, beetles, and mosquitoes. By controlling these insect populations, bats help keep garden pests, such as cutworms or corn earworms, under control.
All bats in Canada are insectivorous, meaning they eat insects. They are very efficient hunters – most consume up to 50% of their body weight in insects each night. Little Brown Bats, the most common bat in Canada, can catch hundreds of mosquitoes in just one hour. Many insects have developed the ability to hear bats even at great distances, so that the mere presence of bats in an area will vanquish insect pests.
Bats are proficient hunters because of their prowess at using echolocation. They send out pulses of sound that echo off objects allowing them to locate and identify their prey. They are so skilled in both echolocation and maneuverability that they can rapidly detect and avoid even the most delicate of obstacles. (The myth that bats get caught in people’s hair is just that – a myth.)
