Why Does Everyone Hate Rats? (Update)

The pervasive human animosity toward rats stems from a complex blend of historical trauma, perceived health risks, and the animals' uncanny success in urban environments. While the brown rat is famously linked to the 14th-century Black Death, recent epidemiological models suggest human parasites, rather than rat-borne fleas, were the primary drivers of that pandemic. Despite this potential exoneration, rats remain "public enemy number one" in cities like New York, where former "Rat Czar" Kathy Corradi and economist Ed Glaeser examine their role as commensal partners that exploit human waste and infrastructure. Beyond the Western lens of disgust, cultural perspectives vary significantly, as seen in India’s Karni Mata Temple where rats are worshipped as reincarnations. Ultimately, the "pest" label reflects a human struggle for dominion; we revile rats not just for the pathogens they carry, but because their thriving populations signal a failure to control the urban spaces we claim as our own.
