"A female rat typically births six litters a year consisting of up to 12 rat pups, although 5-10 pups are more common. Rats reach sexual maturity after nine weeks, meaning that a population can swell from two rats to around 1,250 in one year, with the potential to grow exponentially."[1]

Unless you kill all of them at once and set up some sort of impossibly perfect rat detection system to kill the ones in every building and trash can, how is killing something like on the order of 10 female-year progeny even news? It's like putting a piece of masking tape over a water main break. You have to reduce their food, their ability to reproduce, etc.
