Unknown; possibly a substrate word. Compare Albanian ergjëz (“nit”), Lithuanian érkė (“tick”), Latvian ērce (“tick”), Proto-Slavic *ràkъ (“crayfish”), Sanskrit लिक्षा (likṣā, “nit”) and Persian رشک (rešk, “nit”), which cannot all be derived regularly from the same Proto-Indo-European source. A pre-form *HreK-(e)r ~ *Hrek-en- is possible for the Latin assuming post-PIE thematicization, but the root would remain unidentified.
