And related to what as IWontSubmit referred to above,
The “D.C. Wildlife Protection Act of 2010:
“Provider shall recommend and employ nonlethal means in preference to lethal means for the control of wildlife problems.”
A wildlife control services provider shall not use sticky or glue traps to control any wildlife. (m) a wildlife control services provider shall not use leghold and other body-gripping traps, body-crushing traps, snares, or harpoon-type traps to control any wildlife.” https://wtop.com/news/2012/01/oh-rats-whos-right-about-dcs-rodent-law/
Maybe we could just trap the rats and send them to Guantanamo.
