We perform systematic study of decays of sneutrinos including bosonic decays such as decays into slepton + (W^+ or H^+) as well as fermionic ones in the Minimal Supersymmetric Standard Model (MSSM) with slepton generation mixings and real parameters. We show that the effect of the slepton generation mixings on the branching ratios of the sneutrino decays (both fermionic and bosonic ones) can be quite strong in a significant part of the MSSM parameter space despite the recent very strong experimental limits on lepton flavour violating processes. This could have an important impact on the search for sneutrinos and the determination of the MSSM parameters at future colliders, such as LHC, ILC, CLIC and muon collider.
