"Each city on this list is a major urban area that provides ideal conditions for rats and mice to thrive," said Ron Harrison, an entomologist and Orkin's technical services director. "Commensal rodents depend on humans and their resources to survive, so unless residents and city officials take proactive steps to prevent rodents, infestations can easily get out of hand. It's important to remember that this list is based solely on the number of treatments Orkin performed last year. While your city may not be ranked high on the list, that does not mean you should be any less vigilant."
The rest of the top 20 "rattiest" metropolitan areas cited by Orkin were Seattle-Tacoma, Detroit, Cleveland-Akron-Canton, Baltimore, Miami-Fort Lauderdale, Dallas-Fort Worth, Denver, Houston, Atlanta, Boston-Manchester, Minneapolis-St. Paul, Sacramento-Stockton-Modesto, Syracuse, Indianapolis, and Charlotte.
