In this paper we investigate the strong decays of the two newly observed bottom-strange mesons Bs1(5830) and Bs2*(5840) in the framework of the quark pair creation model. The two-body strong decay widths of Bs1(5830)0\ensuremath→B*+K^\ensuremath- and Bs2*(5840)0\ensuremath→B+K^\ensuremath-, B*+K^\ensuremath- are calculated by considering Bs1(5830) to be a mixture between |1P1⟩ and |3P1⟩ states, and Bs2*(5840) to be a |3P2⟩ state. The double pion decay of Bs1(5830) and Bs2*(5840) is supposed to occur via the intermediate state \ensuremathσ and f0(980). Although the double pion decay widths of Bs1(5830) and Bs2*(5840) are smaller than the two-body strong decay widths of Bs1(5830) and Bs2*(5840), one suggests future experiments to search the double pion decays of Bs1(5830) and Bs2*(5840) due to their sizable decay widths.
