Bexar County starts mosquito remediation after positive West Nile virus tests

A third mosquito found in unincorporated Bexar County has tested positive for West Nile virus, prompting aggressive abatement work in the area around Highway 90 and Cagnon Road, county officials said Wednesday. County workers stepped up efforts to eradicate mosquitos by fogging in public rights of way and in county parks, officials added. Crews fog early in the morning, when mosquitoes are most active, and the county said it employs an environmentally safe compound.
