Action: Create alternative roosts within buildings
- We found no evidence for the effects of interventions to provide alternative roosts within buildings.
'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.
Alternative bat roosts may be created in buildings by providing suitable crevices or spaces. Bat bricks have been suggested as a way to incorporate bat roosts into newly built buildings, and are available for purchase. They are bricks with small crevices that bats may roost in or use as access to a roost in a cavity behind the brick. Heated bat boxes, which simulate the environmental conditions found in roosts within buildings, may also be used to replace roosts lost in developments. We found no studies examining the effects of interventions, including bat bricks or heated bat boxes, to provide alternative roosts within buildings.
