We investigate the prospects for indirect detection of right-handed sneutrinodark matter at the IceCube neutrino telescope in a $U(1)_{B-L}$ extension ofthe MSSM. The capture and annihilation of sneutrinos inside the Sun reachequilibrium, and the flux of produced neutrinos is governed by thesneutrino-proton elastic scattering cross section, which has an upper bound of$8 \times 10^{-9}$ pb from the $Z^{\prime}$ mass limits in the $B-L$ model.Despite the absence of any spin-dependent contribution, the muon event ratespredicted by this model can be detected at IceCube since sneutrinos mainlyannihilate into leptonic final states by virtue of the fermion $B-L$ charges.These subsequently decay to neutrinos with 100% efficiency. The Earth muonevent rates are too small to be detected for the standard halo modelirrespective of an enhanced sneutrino annihilation cross section that canexplain the recent PAMELA data. For modified velocity distributions, the Earthmuon events increase substantially and can be greater than the IceCubedetection threshold of 12 events $\mathrm{km}^{-2}$ $\mathrm{yr}^{-1}$.However, this only leads to a mild increase of about 30% for the Sun muonevents. The number of muon events from the Sun can be as large as roughly 100events $\mathrm{km}^{-2}$ $\mathrm{yr}^{-1}$ for this model.
