Macroscopic dark matter, with the most prominent example of primordial black holes, lies at the high mass end of all dark matter candidates. In this talk, I will show that extreme mass ratio inspirals (EMRIs) are ideal systems in searches for light, in particular subsolar, compact macroscopic dark matter. I will also show that LIGO is able to detect a special class of non-standard EMRIs that we call mini-EMRIs. I will introduce the mini-EMRIs and show that they can be detected with techniques used in current searches of gravitational waves from isolated neutron stars at LIGO.
