Warm, Wet Summer Fuels Mosquito Surge in Chicago Suburbs
Residents in Chicago's south and southwest suburbs are reporting an increase in mosquito activity due to a summer marked by heavy rains and high temperatures. Experts attribute the surge to ideal breeding conditions for mosquitoes, which thrive in warm, wet environments with standing water. The two most common species in the area are those that carry the West Nile virus and the invasive Asian Tiger mosquito. The South Cook County Mosquito Abatement District has been actively spraying to control the mosquito population, focusing on hotspots like Orland Park, Chicago Ridge, and Harvey. The Illinois Department of Health has reported 13 confirmed cases of West Nile virus statewide, including one fatality as of September 1, 2026.
