Rodent-control brand d-Con said the survey, conducted on behalf of the company by Sentient Decision Science, indicates the most rat sightings take place in the South Loop, while rats are also frequently spotted in Lakeview/Wrigleyville, Lincoln Park and the West Loop, the Chicago Tribune reported Tuesday.
Raj Jain, a senior brand manager for d-Con, said the survey represented "a reflection of the economy, and empty buildings, factors like that."
Matt Smith, a spokesman for the city's Department of Streets and Sanitation, said residents in rat-heavy areas should make sure they keep their garbage bins closed and maintain their lawns and gardens.
"The ability to stop rodents from taking up residence in an area lies in the residents' hands," he said. "If rats can't feed, rats can't breed."
