We study the constraints on supersymmetric contributions to b{yields}s transitions from the recent allowed range and measurement of B{sub s}-B{sub s} mixing obtained by the D0 and Collider Detector at Fermilab collaborations at the Tevatron. We compute the upper bounds on the relevant off-diagonal squark mass terms and compare them with the bounds coming from {delta}F=1 decays. We find that the constraints on chirality-flipping mass insertions are unaffected. Conversely, the measurement of B{sub s}-B{sub s} mixing is effective in constraining chirality-conserving mass insertions, and it has striking effects in the case in which left- and right-handed insertions have similar size. Finally, we discuss the phase of the B{sub s}-B{sub s} mixing amplitude in the presence of supersymmetric contributions.
