Precise theoretical predictions for production cross sections of supersymmetric particles are important for searches at the LHC. The occurrence of potentially large logarithmic terms at the production threshold can endanger the perturbative expansion. These terms can be treated systematically to all orders by means of threshold resummation. In my talk, I will shortly present the method of threshold resummation and show the latest results for squark and gluino production cross sections including resummation of soft gluons up to next-to-next-to-leading logarithmic accuracy.
