  We study the role neutrino telescopes could play in discovering
supersymmetric extensions of the Standard Model with a long-lived stau
next-to-lightest superparticle. In such a setup, pairs of staus are produced by
cosmic neutrino interactions in the Earth matter. In optimistic scenarios, one
can expect several pair events per year in a cubic kilometer detector such as
IceCube. We also show that no significant event rate can be expected for decays
of staus stopped in the detector.
