Vermin

Vermin (colloquially varmint(s) or varmit(s)) are pests or nuisance animals that spread diseases and destroy crops, livestock, and property. Since the term is defined in relation to human activities, which species are included vary by region and enterprise. The term derives from the Latin vermis (worm), and was originally used for the worm-like larvae of certain insects, many of which infest foodstuffs. The term varmint (and vermint) has been found in sources from c. 1530–1540s.
