LAS VEGAS – The Southern Nevada Health District is reporting Clark County’s 12th case of West Nile virus. The individual is a male over the age of 50 with the neuroinvasive form of the illness.

    • DEET
    • Picaridin (known as KBR 3023 and icaridin outside the US)

    • Oil of lemon eucalyptus (OLE)
    • 2-undecanone
  • Wear pants and long-sleeved shirts when outdoors.
  • Eliminate areas of standing water, including birdbaths, “green” swimming pools, and sprinkler runoff, which support mosquito breeding.
