Chicago FAQ
How do I report rats in my alley?
Call 311 or use the CHI311 app to file a Rodent Baiting service request. Streets and Sanitation typically baits the alley within seven days and surveys neighboring properties for harborage.
Is my landlord required to fix a rat problem?
Yes. Under MCC 7-28-710 and the RLTO habitability rules, the building owner must rat-proof and eliminate active infestations. Tenants can withhold rent or sue if the landlord ignores written notice.
Can Chicago bait my private yard?
No. The Rodent Control Bureau bait program covers public alleys and city right-of-way only. Private yards are the owner's responsibility, though the city offers free educational inspections on request.
Des Plaines FAQ
How do I report rats in suburban Cook County?
Call the village or city public works first since most suburbs handle rodent complaints locally. Unincorporated residents can contact CCDPH Environmental Health at 708-633-4000 or file an online complaint.
Can I buy rodenticide at a Cook County hardware store?
Yes for over-the-counter first-generation anticoagulants and snap traps. Restricted-use products like brodifacoum require a 225 ILCS 235 commercial applicator license issued by the Illinois Department of Public Health.
Does CCDPH cover my municipality?
Only if your municipality contracts for environmental health services. Roughly 120 suburban Cook villages participate. Chicago, Evanston, Oak Park, and Skokie run their own health departments with separate vector control programs.
