There are many instructions available detailing how to build bat boxes. But it is important to understand that once a bat has used it once it becomes a roost and cannot be removed without licence. It is also important to know that unless you have a Class bat licence the box cannot be checked or disturbed in any way. This includes shining a torch under it to check for bat presence.
Do bat boxes need maintenance?
Sometimes, depends on the type installed. For example, the 1FF Schwegler boxes are described as self-cleaning as the open base allows droppings to fall out. However, some have a closed base which can lead to an accumulation of droppings and birds nest debris.
What time of year do bats use bat boxes?
Bats can use boxes at any time of the year but typically are more likely to be occupied during the active season, May-September as bats often go to underground sites during the winter.
Do bats sleep in bat boxes?
Yes bats will sleep in bat boxes, often moving from one roost to another frequently unless it’s a maternity colony using the box.
Do you have to clean out bat houses?
Only a licenced bat ecologist can clean out a bat box. Contact us to arrange this service.
Can you put a bat box on a tree?
Yes, same protocol as putting on a building but the tree needs to be strong, a suitable diameter, and not dead.
Do birds nest in bat boxes?
Birds can nest in Bat Boxes, but surprisingly bats have been found roosting in the same boxes as birds. If a box has become compacted with bird nest material, it may deter roosting bats and need to be cleared out by a licenced individual.
How we can help
Our Bat Box Check service provides professional monitoring and data collection for all varieties of bat boxes. With a wealth of experience inspecting hundreds of boxes each year, we operate efficiently and with care to minimise any disturbance while collecting vital information. This includes identifying species, conducting DNA sampling, recording weight, sex, breeding status, and roost type. The data gathered can be delivered in a comprehensive report or spreadsheet, customised to suit your specific needs.
