The Ada County Weed, Pest and Mosquito Abatement Department reports that a mosquito trap in northwest Ada County, near Star, has tested positive for the West Nile Virus.

Tested earlier this week, the trap is located in an area north of Chinden Boulevard and Ten Mile Road. Officials say this is the first positive test for West Nile Virus in Ada County so far this year. Another trap along the Boise River near Star showed a “temporary positive” -- and has been submitted to a lab for confirmation.

Ada County Weed, Pest and Mosquito Abatement are actively testing all sites, as well as fogging one square mile around the area that tested positive.  “When we have a positive result like this, we address it immediately,” said Weed, Pest and Mosquito Abatement Director Brian Wilbur. “We will continue to keep a close eye on these locations, in addition to our regular treatment efforts throughout all of Ada County.”

Mosquitos are most active between dusk and dawn and residents should take measures to protect themselves and their families from mosquitoes that could carry it. Remember the D’s:

-- DRAIN any standing water on your property that may produce mosquitos.

-- DRESS appropriately by wearing light colored, loose long sleeves and pants when outdoors.

-- DEFEND yourself against mosquitos by covering up exposed skin and apply DEET or another EPA-approved insect repellent.
