Mosquitoes collected from a Canyon County Mosquito Abatement District trap on Friday were tested over the weekend, according to a Monday notice from the district.
The trap was in the Dixie Flats area along Boise River Road.
In response, ultra low volume fogging will begin Monday night and continue through the week in the area, including within both Parma and Notus, the notice states. The district’s regular operations will continue — among them, larvicide operations.
Mosquitoes carrying West Nile were found earlier this year in Emmett. Southwest District Health on Monday reported three additional Gem County traps with mosquitoes that tested positive for the virus, at Shadow Butte Elementary, Gem Avenue and Black Canyon Highway, and Hanna Avenue and Black Canyon Highway.

The current heat wave has led to a spike in the type of mosquito that carries West Nile, according to the Canyon County district.
Most people infected with it show no symptoms. About one in five end up with a fever, headache, body aches, vomiting, a rash or other symptoms; a few — less than 1 percent — develop a serious inflammation of the brain that can cause permanent damage or death.
West Nile has been present in Idaho since 2004, arriving in a rush across most of the state in 2006 in a year that tallied 23 deaths related to the virus. In recent years it has infected a couple of dozen of Idahoans a year, with no more than one or two deaths reported each year after 2006.
The Canyon County abatement district offers the following advice (referred to as the “7 Ds”) to avoid mosquito bites:
Drain any standing water on your property that may encourage mosquitoes. Also, don’t over-irrigate.
Stay indoors around dawn and dusk, when mosquitoes are most active.
Dress in long-sleeved shirts and long pants when outdoors.
Defend yourself with an insect repellant. The abatement district advises one with at least 30 percent DEET. For those concerned about chemicals, Consumer Reports says it’s tested alternatives this year that for the first time, performed better than DEET.
Keep door and window screens in good condition.
Don’t hesitate to seek the district’s help addressing your mosquito problems.
