Here's something I wonder about this Orkin study. Their methodology is by number of rodent treatments by city. Is that just because people in Chicago are more worried about rats than the actual existence of rats? Chicago is a huge city by land area, much larger than NYC.
Never saw a rat in my decade of "serving time" as a homeowner in Chicago. Anecdotal evidence, of course. But I don't even recall seeing one when I worked in or near the loop.
Other than a politician, naturally.
