Let bats be low-cost insect exterminators
Though creepy crawlies may be repulsive to some, many bats eat little else and keep the insect population under control
Common pipistrelles emerge around 20 minutes after sunset. The most widespread bat in Europe hunts winged insects like flies and mosquitoes using echolocation. Their high-pitched chirps fall just within the human hearing range, and many gardenowners
are unaware of the bats’ presence. You may choose to erect a bat box, but it isn’t necessary to house bats in your back yard. Pipistrelles roost in small groups in trees and small hollows, so it’s likely you already have a fully furnished bat cave.
