The biobased exclusion flap is used to create an escape route for bats from a sealed cavity or hollow spaces in a building. The purpose of the VdV exclusion flap is to ensure that bats can leave the building but cannot return. Our flap is unique in the market because of its price, usability, compact size for shipping, and suitability for all bat species.
Thanks to its innovative design, the exclusion flap is one of a kind. The updated design makes it easier to apply to horizontal seams and cracks. By simply trimming the upper edge of the flap, it can be mounted under fascia boards or roof trims. This also results in less waste and reduces the risk of breakage!
