the tiny squatter living rent-free on your face right now, eating dead skin

means A mite is any of countless tiny eight-legged arachnids related to ticks and spiders, many so small they're invisible to the naked eye, living everywhere from dust to skin to soil; the word also means a very small amount or a tiny creature in general.

from From Old English 'mite,' a name for a tiny biting insect, traceable to a Germanic root (compare Dutch 'mijt' and German 'Miete') that likely meant 'something cut small' or 'a cutter' — fittingly, a thing defined by its smallness. The sense of 'a tiny amount' grew from this, helped along by the 'widow's mite' of the Bible, a coin of almost no value.
