Chicago-area biting flies surge this late summer, sparking health warnings
Residents across the Chicago area report a surge in biting flies this late summer, with social-media posts describing widespread bites. The Illinois Department of Public Health notes that stable flies are common this season, bite ankles, and can fly miles from larval habitats near vegetation and shorelines. Prevention centers on avoiding peak bite times, wearing long, light-colored clothing, and using repellents as a last resort, though complete control is difficult. Mosquito activity is also up due to warm, damp weather.
