Residents Asked to Eliminate Green Pools to Help  `Fight the Bite' During Mosquito Season

With the onset of mosquito season in Southern Nevada, the public can help eliminate the blight and health dangers of green pools by reporting them to local code enforcement agencies. If located in unincorporated Clark County, call (702) 455-4191 or file a complaint through the County website at   

Green pools are pools that have been neglected for so long that their water has turned green from algae and bacteria. Green pools, ponds and other standing bodies of water can become breeding grounds for mosquitos, which can carry serious diseases such as the West Nile and Zika viruses. Last year the County responded to 168 complaints about green pools.

“Green pools are not only ugly but also breeding grounds for mosquitos,” said Clark County Commissioner Marilyn Kirkpatrick, a member of the Southern Nevada Health District’s Board of Health. “It’s a priority to respond to complaints about green pools because they put the public health of our community at risk. You also can prevent mosquitos outside your home by making sure you don’t have any water collecting in planters, buckets or from leaky drip systems or sprinklers.”

Mosquito activity tends to increase in Southern Nevada during the hotter months but varies year to year. Seasonal efforts to eliminate green pools provide fewer opportunities for mosquitos to breed which can lower the risk for mosquito-borne illnesses. In 2019, the Health District reported 43 cases of West Nile virus in the County; one case was reported in 2020; and none were reported in 2021. Health officials say even small amounts of standing water can support mosquito breeding. Tips to “fight the bite” are on the Health District’s website at Suggestions include:

  • Avoid spending time outdoors when mosquitos are most active, notably at dawn and dusk.
  • When outdoors, use insect repellants containing DEET, Picaridin or oil of lemon eucalyptus.
  • Wear pants and long-sleeved shirts when outdoors and spray repellent on clothes and exposed skin.
  • Make sure doors and window have tight-fitting screens without tears or holes.
