We present ultra-deep extra-galactic counts at 24 microns obtained from the HDF-North and ELAIS-N1 Spitzer public surveys. A total of 2000 and 1300 sources are detected in each field, respectively, down to a 3-sigma sensitivity limit of 20 micro-Jy. Using Monte Carlo simulations, we measure an 80% completeness limit of 80 micro-Jy and correct the counts down to the 50% completeness level. Beyond this limit, the extra-galactic confusion noise due to faint sources becomes important. We use simulations to reproduce the distribution of pixel fluxes in the 24 micron images, thereby estimating the counts down to a flux limit of 10 micro-Jy.
