We discuss a possible interpretation of the scalar Bs0*(5725) and axial Bs1(5778) bottom-strange mesons as hadronic molecules-bound states of BK and B*K mesons, respectively. Using a phenomenological Lagrangian approach we analyze the strong Bs0*→Bsπ0, Bs1→Bs*π0 and the radiative Bs0*→Bs*γ, Bs1→Bsγ, Bs1→Bs*γ, Bs1→Bs0*γ decays. We give predictions for the decay properties: effective couplings and decay widths.
