Direct detection experiments are looking for rare interactions between dark matter (DM) particles from the galactic halo and atoms of a detector. For larger cross sections, such scatterings can occur even before the DM particle enters the laboratory. I will discuss the phenomenological implications of “pre-detection” scatterings inside the Earth and Sun, and how they can both extend and reduce the sensitivity of terrestrial DM searches.
