The Benton County Mosquito control board plans to spray some areas of the county this week.

The measures being taken, including some aerial spraying, are to counter the discovery of insects infected with the West Nile Virus. They were found near Mabton, Prosser and Grandview.  

This is the first discovery this season in Benton County for the virus this season.   Infected mosquitoes were detected in Yakima County in the lower part of the valley in June and July.

The aerial spraying is planned for Thursday, beginning around 9 p.m.
