Philly stays put on the list, but last year it had moved up three spots.
PHILADELPHIA (WPVI) -- Philadelphia has a rat problem. But there are six other cities where rodents are causing a bigger ruckus.
That's according to Orkin's 2021 "Top 50 Rattiest Cities List," which was released Thursday.
Philly remains at No. 7 on the list, same place it was last year when it moved up three spots from 2019.
Chicago took the top spot for the seventh consecutive time, followed by Los Angeles, New York, Washington, D.C., San Francisco and Baltimore.
Orkin rated cities according to the number of new rodent treatments performed from September 15, 2020 to September 15, 2021. The ranking includes both residential and commercial treatments.
"During an unprecedented last year, the visibility of rodents increased, creating concern for homeowners and business owners alike. The pandemic-driven closure of restaurants forced rodents to find new food sources. Without food waste to consume, these pests were seen scavenging new areas and exhibiting unusual or aggressive behavior," the company said in a press release Wednesday.
Here is how the top 10 looks:
2. Los Angeles
3. New York
4. Washington, D.C.
5. San Francisco
