  We study the implications of LHC results for the abundance of long-lived
staus after freeze-out from thermal equilibrium in a super-WIMP dark matter
scenario. We classify regions in the MSSM parameter space according to the stau
yield, considering all possible co-annihilation effects as well as the effects
of resonances and large Higgs-sfermion couplings. Afterwards, we examine the
viability of these regions after imposing experimental and theoretical
constraints, in particular a Higgs mass around 125 GeV and null-searches for
heavy stable charged particles (HSCP) at the LHC. We work in a pMSSM framework
and perform a Monte Carlo scan over the parameter space. To interpret the HSCP
searches in our scenario, we consider all potentially important superparticle
production processes, developing a fast estimator for NLO cross sections for
electroweak and strong production at the LHC. After applying all constraints,
we find that stau yields below 10^-14 occur only for resonant annihilation via
a heavy Higgs in combination with either co-annihilation or large left-right
stau mixing. We encounter allowed points with yields as low as 2x10^-16, thus
satisfying limits from big bang nucleosynthesis even for large stau lifetimes.
