Pest-control company Orkin says Chicago’s ten-year streak atop its annual “Rattiest Cities” rankings has ended. For 2025, Los Angeles climbs to No. 1, with Chicago at No. 2 and New York at No. 3 on the Top 50 list. The rankings are determined by the volume of new rodent service calls, reflecting where residents and businesses are seeking professional help most often.
Orkin attributes L.A.’s rise to year-round mild weather, a vibrant dining scene, and dense neighborhoods that provide plentiful food and shelter—from busy commercial districts to tucked-away alleyways—creating ideal conditions for rodent activity.
