> can we release a rat specific poison or is that impossible without harming the entire ecosystem? Many cities, like Baltimore, have an entire department devoted to "rat eradication" (https://publicworks.baltimorecity.gov/Rat-Eradication https://publicworks.baltimorecity.gov/Rat-Eradication). Some have a "rat czar" "Eradication" is a bit of a misnomer because it is not possible to actually eliminate rats from a city. The goal is to keep them from getting out of control. However bad a rat problem is, it can get much worse if unchecked. These programs use a combination of public education, on-demand services (poison, burrow-treatments), and other interventions like city codes for proper garbage containers/handling etc.
