This Is How a Society Commits Suicide...

Selected more or less at random from the new Washingon, D.C. regulations (PDF) covering (amongst other things) rat exterminators:

(i) A wildlife control services provider shall make every reasonable effort to preserve family units using humane eviction or displacement and reunion strategies and shall not knowingly abandon dependent young wildlife in a structure.
(j) Wildlife shall not be kept in captivity longer than 36 hours unless specifically
authorized by the Department or unless reunion attempts are being employed. In the case of attempted reunion, a wildlife control services provider may hold wildlife in captivity for up to 72 hours.
(k) Captured wildlife shall be transported in covered, secure containers in such a way as to:

      (1) Minimize stress to the animal and its exposure to the elements by covering
the trap or vehicle with appropriate material;
      (2) Ensure that the covering is of such material that the animal has an adequate
supply of air to prevent overheating; and
      (3) Minimize potential hazards to the general public.

(l) A wildlife control services provider shall not use sticky or glue traps to control any wildlife.

The city is now obligated to enforce these new regulations.  That means a small army of unionized inspectors and (given that we're talking about Washingon, D.C.) armed enforcement officers.  This, in a city where more than half the kids drop out of high school.  When the priorities of a society favor the rats over its own young, you know the end is near (for the society, not the rats)...
