In this paper we investigate the strong decays of the two newly observed bottom-strange mesons B{sub s1}(5830) and B{sub s2}{sup *}(5840) in the framework of the quark pair creation model. The two-body strong decay widths of B{sub s1}(5830){sup 0}{yields}B*{sup +}K{sup -} and B{sub s2}*(5840){sup 0}{yields}B{sup +}K{sup -}, B*{sup +}K{sup -} are calculated by considering B{sub s1}(5830) to be a mixture between |{sup 1}P{sub 1}> and |{sup 3}P{sub 1}> states, and B{sub s2}*(5840) to be a |{sup 3}P{sub 2}> state. The double pion decay of B{sub s1}(5830) and B{sub s2}{sup *}(5840) is supposed to occur via the intermediate state {sigma} and f{sub 0}(980). Although the double pion decay widths of B{sub s1}(5830) and B{sub s2}*(5840) are smaller than the two-body strong decay widths of B{sub s1}(5830) and B{sub s2}*(5840), one suggests future experiments to search the double pion decays of B{sub s1}(5830) and B{sub s2}*(5840) due to their sizable decay widths.
