If the thought of a rat scampering across the ground makes your skin crawl, San Francisco or Oakland might not be the place for you.
The two Bay Area cities are ranked No. 4 on Orkin's top-50 "rattiest" regions list.
Orkin compiled the list by tallying the amount of times company workers responded to a rodent treatment call in a given city between September 2016 and September 2017. Chicago topped that list, followed by New York and Los Angeles, respectively.
Fall marks the beginning of rodent season, according to Orkin. The cooler temperatures prompt rats and mice to scurry indoors as they seek shelter from the elements.
