Mosquito Spray Locations This Week
CDPH detected an increased number of mosquitoes that carry West Nile virus, triggering a decision to spray insecticide this week in three communities to kill adult mosquitoes. On Wednesday, August 6, 2025, O'Hare was sprayed; on Thursday, August 7, Avondale and Logan Square will be sprayed. These are the second spraying events to occur in the city this season.
Weather permitting, the spraying will begin at dusk on August 6 and August 7 and continue through the night until approximately 1 am, with licensed mosquito abatement technicians dispensing an ultra-low-volume spray from trucks.
