According to a first aspect the invention relates to a device, for confining bumblebee (Bombus spp.) workers, such as a nest box. The device comprises a number of barriers forming a number of chambers suitable for confining bumblebee workers. The barriers comprise a laminate comprising a celluloseboard, preferably solid paperboard, covered with a 10-500 μm thick layer of a material comprising a number of polymers. The polymeric material having a tensile strength of at least 25 MPa and an indentation microhardness of at least 80 MPa. Further aspects of the invention relate to the use of the laminate and a method for confining bumblebee (Bombus spp.) workers.
