Chicago has become the latest city to use dry ice to combat its rodent problems, dnainfo.com reported.

At the end of August, crews with the city's Streets and Sanitation Department started putting dry ice — frozen carbon dioxide — into rat burrows and sealing up the holes with dirt and newspaper.

The city will try and replicate the success of cities like New York and Boston, which have seen inroads with the method, said Streets and Sanitation Commissioner Charles Williams.
