Aerial Spraying to Combat West Nile Virus


Aerial spraying of 15,000 acres in Hermiston will take place this week to combat West Nile virus after it was detected last week.

The West Umatilla Mosquito Control District will be conducting targeted aerial mosquito control spraying with a twin engine airplane after sunset on Thursday, July 30, weather permitting. The application is taking place to protect the public against mosquitoes carrying West Nile virus in several areas of Western Umatilla County. The district has two confirmed positive samples. Both samples were collected last week and confirmed later in the week by the Oregon State University Veterinary Diagnostic Lab in Corvallis.

The first sample was collected in the Power City area and the second was located off of Spearman Road east of Hermiston.

A total of 15,000 acres are in the target area that includes the Diagonal Road area between the city of Hermiston and the Highway 730 Junction, portions of the Hat Rock area, and the Power City area.
