  We discuss the relic abundance of massive long lived colored particles with
mass of the order of 1 TeV. We first examine the case where the massive colored
particles have the standard color only. Next we consider the "Quirk Model"
suggested by M. Luty, in which the colored particles transform under an
additional non-abelian gauge group with a scale much smaller than the
particles' mass. In both cases, the relic abundance is reduced via a "late"
hadronic annihilation stage. In the second case the relic Quirks bind to
ordinary quarks forming fractional charged objects and also anomalous heavy
isotopes, and the bounds on the relic abundance become extremely severe. The
force between Quirks, however, has a new confining part that manifests via
macroscopic strings and the resulting efficient "very late" annihilations
reduce the relic abundance to acceptable levels. The prospects of creating and
detecting such particles at LHC and the fate of the particles created are
discussed.
