Chicago neighborhoods now have a working, community-led alternative to poison baiting: a rat birth control pilot run by the Wicker Park Bucktown Special Service Area #33, a taxpayer-funded business improvement district covering parts of Western, Damen, Ashland, Milwaukee, North and Division avenues. Since April 2025, the SSA has deployed 190 bait stations holding SenesTech's Evolve Rat Birth Control across roughly two miles of alleys and landscape beds, and organizers report early success. Here is how the program works, what results its backers claim, and how it stacks up against the city's traditional rodenticide approach.
Understanding Chicago's Rat Challenge and Integrated Pest Management (IPM)
Integrated Pest Management is the framework experts use to judge whether a rat control program addresses root causes rather than symptoms. A 2026 audit of Chicago's Department of Streets and Sanitation rat abatement program by the city's Office of Inspector General found that the Bureau of Rodent Control's approach did not align with IPM because it used anticoagulant poison as its primary method of abatement. The audit also noted the city did not integrate programs that address root causes such as trash removal, weed cutting in vacant lots, habitat modification, and enforcement of sanitation, restaurant and building codes. The audit pointed to New Orleans' rodent control board as a contrast: that department does not bait burrows at all, instead using nontoxic management, inspections and resident education.
