"Rattiest Cities in America: Chicago, Ohio, Portland, NYC, and Houston Ranked"

Pest control company Orkin has declared Chicago as the "rattiest" city in the United States for the eighth consecutive year. Orkin determines the rankings based on the number of new pest control treatments for rodents in a 12-month period. Los Angeles and New York City switched positions this year, with Los Angeles taking second place and New York City ranking third. Washington, D.C., and San Francisco rounded out the top five. The rankings highlight the ongoing issue of rodent infestations in urban areas, with approximately 21 million U.S. homes affected each fall season.
