This oak/larch double chambered box provides habitat for many bats. The heavy construction provides good insulation and longevity, as well as preventing predators from chewing the entrance slot. There is an access ladder and hinged front door providing access for inspection and cleaning. Bat boxes should be sited 2.5 to 5 mtrs high (depending on whether low or high flying bats are sighted) Bats may change direction of roost preferred, dependant on weather conditions and season. Ideally three boxes should be fixed on a tree facing north, or south to south east.
