Pest pressure in Illinois

Illinois faces heavy pest pressure driven by Chicago's density and the state's humid summers. Chicago has consistently ranked among the most rat-infested U.S. cities, and its apartment stock supports steady German roach and bed bug activity. Suburban and downstate Illinois deal more with seasonal ants, wasps, and fall rodent migration.
