Four mosquito traps in Canyon County have tested positive for West Nile virus – and officials are urging the public to use insect repellent and cover exposed skin.
Three of the traps were along the Boise River in Parma, and the fourth was at Public Access 1 on Lakeshore Drive at the Deer Flat National Wildlife Refuge.
Ultra low-volume fogging was done Friday night after the traps were retrieved and found to have high numbers of Culex mosquitoes, according to the Canyon County Mosquito Abatement District. The fogging will continue this week in Parma and south of Lake Lowell, along Lakeshore Drive.
Aerial treatments were also done along the Boise River near the Highway 95 bridge, another place where large numbers of Culex mosquitoes were found.
Officials say West Nile virus activity seems to be occurring west of Highway 95 from Parma to the Oregon state line.
