We have performed a search for B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -} and B{sup 0}{yields}{mu}{sup +}{mu}{sup -} decays in pp collisions at {radical}(s)=1.96 TeV using 2 fb{sup -1} of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron Collider. The observed number of B{sub s}{sup 0} and B{sup 0} candidates is consistent with background expectations. The resulting upper limits on the branching fractions are B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -})<5.8x10{sup -8} and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -})<1.8x10{sup -8} at 95% C.L.
