NHBS’s new Triple Chamber Bat Box is available for the first time this autumn. The new bat box has three large chambers providing its inhabitants with a huge living area (compared with most other wooden bat boxes). Consequently, they are particularly well-suited to large colonies, including maternity colonies. Most crevice-dwelling bat species are likely to be attracted including Pipistrelles, Brown long-eared bats, and Daubentons. Species which may sometimes use these boxes include other Myotis species and Noctules.
The boxes are very deep, providing the bats with a stable draught-free environment and plenty of space for individuals to cluster together or disperse, and for the sexes to mingle or separate. Triple chamber boxes have proved to be a success in the U.S. where it is thought that the extra space provided gives bats the room to interact more normally. The boxes open at the top and are 60 cm high with a small aperture at the base of the box for bats to enter and exit. They are narrow (14 cm) and can easily be hung on both trees and buildings. The Triple Chamber Bat Box is constructed from European Redwood harvested from a sustainably managed forest.
