  We consider the possibility that the cosmological dark matter consists of
particles very close in mass to new colored particles below the TeV scale.
While such a scenario is inherently difficult to directly confirm at colliders,
we find that indirect dark matter searches may be a powerful alternative. In
particular, we show that in this case dark matter annihilation to
quark-quark-gluon final states can give rise to significant antiproton (but
also gamma-ray) fluxes, and compare the resulting constraints to bounds from
direct searches at LEP, the Tevatron and the LHC. For supersymmetric
neutralinos degenerate with squarks, e.g., antiprotons can give rise to more
stringent constraints for masses below around 45-80 GeV.
