๐ฆ The Allegheny County Health Department will be treating portions of Aspinwall, Troy Hill, Reserve Township, Allegheny Commons, The Mexican War Streets, and Manchester for mosquitoes. Positive tests for West Nile Virus were recently found in those areas. Share this with anyone you know in those neighborhoods.
๐ Crews will use a truck mounted sprayer on Wednesday, September 9, from 8:00 p.m. to 11:00 p.m., to lower the local mosquito population and minimize the risk of human disease transmission. Rain date is Thursday.
