The U.S. Cities With the Biggest Rat Problems, Ranked

The results are in, and Los Angeles has been named America's rattiest city. Did your city make the list for the top 10 rattiest cities in the country? Read on for the details.

Los Angeles Declared Rattiest City in the U.S.

Pest control company Orkin has released its list of rattiest cities in the U.S. Los Angeles is atop the list that no city wants to be on, followed by Chicago at number 2, New York City at number 3, San Francisco at number 4, and Washington, D.C., at number 5.

Orkin said that the year-round mild weather in Los Angeles combines with its densely populated neighborhoods to support a robust rat population. The rodents also have plenty of access to food, water, and shelter, creating a perfect storm of conditions for rats and mice to thrive. In short, the same conditions that attract humans to Los Angeles also attract rodents.

Detroit came in at number 6, inching up one spot from last year on the notorious list. Cleveland came in at number 7, moving up four spots since last year. Denver climbed two spots to land at number 8, while Philadelphia dropped one position to rank number 9. Rounding out the top 10 is Baltimore, climbing two notches since last year.
