We consider direct detection of neutralino WIMP and the upward‐going muon flux due to the WIMP annihilations in the cores of the sun and the earth, including the upper bound on the branching ratio for Bs → μ+μ− decay. We find that the constraint from Bs → μ+μ− is very strong in most parameter space, and excludes substatial part of the supergravity parameter space regions where the direct detection rates are within current experimental sensitivities and the expected upward‐going muon fluxes are within the expected reach of IceCube.
