New York City turns to dry ice to control its rat population

Chicago, Boston and Washington, D.C., among other cities, are also using dry ice to help control their rat populations. New York City’s $40 million rat eradication program, launched in 2017, was created to address public health and quality of life issues in the city’s three rattiest areas. The city is tracking its progress through inspections of private and public property, schools and parks to record burrow counts and other evidence of rats, like droppings or tracks.
