The Windy City has topped the list of the rattiest cities in the United States for the sixth year in a row.
Orkin, an Atlanta-based pest control service, ranks U.S. cities based on the number of new rodent treatments from Sept. 1 to Aug. 31 of each year. The result is a list of 50 cities, with most changing spots each time the list is updated. Chicago, however, is still No. 1.
