Abstract We calculate the masses and decay constants of the P-wave strange-bottomed mesons Bs0 and Bs1 with the QCD sum rules, and observe that the central values of the masses Bs0 and Bs1 are smaller than the corresponding BK and B*K thresholds respectively, the strong decays Bs0→BK and Bs1B*K are kinematically forbidden. They can decay through the isospin violation processes Bs0→Bsη→wBsπ0 and Bs1→ Bsη→ Bs*π0. The bottomed mesons Bs0 and Bs1, just like their charmed cousins Ds0(2317) and Ds1(2460), may be very narrow.
