Orkin gives Los Angeles the unwanted title of U.S.’s ‘rattiest’ city

The exterminator company Orkin says that, for the first time, Los Angeles has topped its list of Top 50 Rattiest Cities, a dubious distinction based on U.S. locales with the most calls for new rodent services.

Orkin’s recent list was compiled by tracking new rodent services in owner-occupied residences from Aug. 20, 2024, to Aug. 21, 2025. Chicago was second, New York third and San Francisco fourth.

The company cites “year-round warm weather, a booming culinary scene and dense neighborhoods that offer ample access to food and shelter” as factors for the ascension of Los Angeles to the top spot .

Orkin said rats pose the following risks for property owners:

— structural damage: Rodents gnaw through walls, wiring and even pipes;

— health concerns: Rodents are known carriers of illness
