This built-in bat box is ideal for compensating for a summer and/or mating roost during renovation or new construction.

The bat box is built in combination with the entrance stone IB VL 09 or in walls where the facade cladding is chosen by the user, such as in timber frame construction. In the latter application, it is necessary to create a proper connection to the box’s entry opening in the facade cladding. This built-in bat box is also suitable for surface mounting.

The box is made of exterior plywood with one interior side finished with spray cork. The layer of spray cork on the outside of the box also provides additional insulation.

The sloped design on the inside of the IB VL 31 ensures that bat droppings are automatically discharged through the entrance stone, preventing accumulation inside the box.

Suitable as a summer and mating roost for:

– Common pipistrelle
– Nathusius’ pipistrelle
– Soprano pipistrelle

The noctule and small maternity colonies of pipistrelles can also use this box. Additionally, the box can be used as a winter roost. It is also possible that other species may use this built-in box.

  • Preferably install this box in multiple locations on the façade. Vary the height and orientation to different wind directions.
  • Install the box in the wall at a minimum height of 4 meters.
  • If used with the IB VL 09, first embed the entrance brick and let it dry. Then place the built-in box against the inner side of the entrance brick so that the openings align perfectly.
  • The built-in box can be secured using wall ties (not included) or fixed in other ways at your discretion.
  • Do not install boxes directly above doors or windows.
  • Ensure a clear flight path and never place boxes in or under artificial lighting

Thanks to the sloped interior, droppings can easily roll out through the entrance brick. Moreover, the bats’ crawling in and out will help push out any remaining droppings. It is advisable to check annually whether the entrance opening is still clean.
If necessary, it can be cleaned with a brush.
