No one ever wants to encounter rats for any reason, but avoiding them may be difficult, depending on where you live.  

Orkin released a list of cities in the U.S. with the most rats. The pest control company created its rankings based on the efforts made in these areas to manage the rodent problem as well as the number of new rodent and pest control treatments performed at residential and commercial spaces nationwide between Sept. 1, 2022 and Aug. 31, 2023.
