The invention is characterized by the creation of shelters for bats in a kind of "Carport" by the installation of large -sized bats.The surface size of such a protective wall must be at least 20m2 for suitability for purpose and can be produced both rectangular and in all other geometric forms.The bat -sized boxes are made of sawdust, non -chemically charged wood in sandwich construction and have impact slits between 12 and 40mm depending on the target species. Material strength from 19mm.The distances of the base plates (front wall "back wall") are in the lower part of the respective box between 20 and 40mm and extend upwards to 5 to 0 mm. As a climbing aid for bats, customary plasters of mesh width 3 to 5mm can be fixed within the boxes.The installation of the bat -sized boxes takes place in a vertical manner below the roof construction of the building. Depending on the target species, the control area of the boxes is set at 1.5 to 3m height and is located in the bottom -facing part of the box. The layout of the control area can vary depending on the type of target and the geographical orientation of the structure. The height of the bat enclosures shall be at least 50 cm above the range of influence.The width of the large boxes shall be at least 80cm. Larger widths are harmless.Depending on the roughness of the wood used, the area of influence itself must be designed by means of appropriate measures (wood roughness, adhesion of sand, application of tile adhesives, etc.).The bat -sized cages are protected from weather by a roof cover. Hard roof variants can also be used, such as trapezoidal leaves or wooden shields. Covering with wooden substructure and sticky bitumen is equally effective, but should be critically questioned for environmental reasons.
