  The promising neutralino dark matter particles generically condense into
numerous earth-mass dark halos with smaller substructures suppressed by free
streaming\cite{berezinsky}. The recent {\it Letter to Nature}\cite{moore}
claims that these 0.01pc-sized dense halos emerged at redshifts 60--26 are
rarely destructed inside galaxies, hence the nearest halos at about 0.1pc from
Earth are bright in annihilation-powered gamma-rays, but are inaccessible to
direct detections. However, most mini-halos reaching solar neighbourhood should
experience strong impulses by individual stars in the Galactic disk and bulge,
and have been torn into pc-long tidal streams over a Hubble time with only
modest overdensity, reducing indirect annihilation signals. Sweeping across the
solar system per century, mini-streams leave directional and temporal
signatures for direct searches of neutralinos.
