Vermin

[1][3] The term "vermin" is used to refer to a wide scope of organisms, including rodents (such as rats), cockroaches, termites, bed bugs,[4] stoats, sables.

Historically, in the 16th and 17th century, the expression also became used as a derogatory term associated with groups of persons typically plagued by vermin, namely beggars and vagabonds, and more generally the poor.

[5] Disease-carrying rodents and insects are the usual case, but the term is also applied to larger animals—especially small predators—typically because they consume resources which humans consider theirs, such as livestock and crops.

[1] Varmint or varmit is an American-English colloquialism, a corruption of "vermin" particularly common to the American East and South-east within the nearby bordering states of the vast Appalachia region.

The term describes species which raid farms from without, as opposed to vermin (such as rats) that infest from within, thus referring mainly to predators such as feral dogs, foxes, weasels, and coyotes, sometimes even wolves or rarely bears, but also, to a lesser degree, herbivores and burrowing animals that directly damage crops and land.
