Dayton Conducts Mosquito Spraying After West Nile Virus Detection

August 7, 2026

Dayton & Montgomery County Public Health conducted targeted mosquito spraying this week after mosquitoes carrying West Nile virus were detected in surveillance traps. The action comes as mosquito surveillance programs in several Ohio communities have reported West Nile-positive mosquito pools this summer, prompting increased monitoring and control efforts.

No human cases had been reported in the affected Dayton area and encouraged residents to reduce standing water, use EPA-approved insect repellent and wear protective clothing when outdoors.
