The diffusive propagation of strangelets through the interstellar medium and their interactions with Galactic supernova remnants are studied with the help of three-dimensional numerical simulations. Using the events of the Sanriuku Balloon Center (HECRO-81) experiment and, alternatively, the reported Centauro events to normalize the flux onto the Earth, the confinement time, injection energy, differential spectrum, and fractional mass in the Galaxy are addressed. We discuss the consistency of the results with both the popular compact binary coalescence and Type II supernova injection scenarios. We find, in agreement with previous estimates, that if any of those tentative identifications of strangelets is correct, the Galaxy is inevitably contaminated with strangelets, and there is no room for neutron stars (thus, either strange stars can glitch, or the existence of strangelets in cosmic rays can be ruled out). The simulations may prove useful to guide future searches of strangelets by new experiments.
