City parks, drainage easements and basins
The City of Scottsdale continues to treat all City parks, drainage easements and basins with larvicides (environmentally-friendly oils and briquettes) on an as-needed basis. These public areas are continually monitored by trained city staff in accordance with the guidelines set forth by the Maricopa County Environmental Services division.
WestWorld of Scottsdale
Designed by the Bureau of Reclamation, the WestWorld flood detention basin, located at 16601 N. Pima Rd., was originally configured as a "low spot" or drainage basin to retain area storm water. When standing water is present, this area is tested and treated for mosquito larvae every two weeks by a city-contracted company.

West Nile Virus & Symptoms
The principle route of human infection with West Nile virus is through the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds, which may circulate the virus in their blood for a few days. The virus eventually finds its way into the mosquito's salivary glands.
During subsequent blood meals, the virus may be injected into humans and animals, where it can multiply and possibly cause illness. Most people who are infected with the West Nile virus will not have any type of illness. It is estimated that 20% of the people who become infected will develop West Nile fever within 3 to 14 days.
Minor Symptoms: fever, headache, body aches, occasionally a skin rash on the trunk of the body and swollen lymph glands.
Severe Symptoms (West Nile encephalitis or meningitis): headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis.
If bitten by a mosquito:
- Wash bite with soap and water
- Apply cold cloth for swelling
- Apply anti-itch medication
- Watch for symptoms
- Seek a doctor's help if experiencing West Nile symptoms
