Is Chicago doing enough to combat rats?

Chicago is no longer the rattiest city in the country. That’s according to the national pest control company, Orkin. But many, including a spokesperson for Chicago’s Department of Streets and Sanitation, question the corporation's methodology and findings as issues with the rodents persist across the city. Cole Stallard, commissioner of Chicago’s Streets and Sanitation, says while the agency is getting better at rodent control, Chicagoans also need to do their part and clean up after themselves and their pets.On Say More, callers share their experiences in combatting rat infestations and ask for more help from the city.  GUEST: Cole Stallard, Commissioner, Chicago Department of Streets and Sanitation
