City of New Orleans Reports West Nile Infected Mosquitoes in Orleans Parish

NEW ORLEANS — The City of New Orleans Mosquito, Termite and Rodent Control Board (NOMTRCB) reports that mosquitoes collected this week from the East Bank of Orleans Parish tested positive for West Nile virus (WNV). WNV cycles between wild birds and mosquitoes and can be transmitted to people by the bite of an infected mosquito. No human cases of WNV in Orleans Parish have been reported.

Treatments will take place tonight in the area bounded by Leon C. Simon Drive, Elysian Fields Avenue, Lombard Street and Peoples Avenue from 8 p.m. to 11 p.m., weather permitting. Truck applications this evening will target the “Southern house mosquito” Culex quinquefasciatus, the primary vector of West Nile virus in our region. While the majority of human West Nile infections are asymptomatic, common symptoms can include headache, body aches, joint pain, vomiting, diarrhea or rash. In rare cases, the virus can cause serious symptoms, especially for people that are above 65 years old or immunocompromised.

NOMTRCB is urging people to protect themselves from mosquito bites by limiting outdoor activities between dusk and dawn, using EPA-approved insect repellents, and mosquito-proofing residences by maintaining screens on windows and doors.

We also ask that residents remain vigilant in emptying water-filled containers around the home and yard to reduce potential mosquito breeding sites. Change water every week in containers that cannot be removed, such as birdbaths, sugar kettles, pools and ponds. It takes seven days for mosquitoes to grow from an egg to an adult, making it important to inspect your yard every week. Remove trash and clutter including tires, buckets, tarps, and any other items that can collect water. Make sure swimming pools and fountains are functioning and that water is circulating.

For additional information about the West Nile virus, visit the Centers for Disease Control and Prevention website:


Protecting Yourself

  • Limit outdoor activities between dusk and dawn.
  • Use air-conditioning and make sure window and door screens do not have holes to prevent mosquitoes from getting inside.
  • If outside for long periods of time, wear long-sleeved shirts and pants.
  • Use insect repellents containing EPA-registered active ingredients including DEET, picaridin, IR3535, or oil of lemon-eucalyptus.
  • When using insect repellent, always follow the recommendations on the product label.

Protecting Your Home

  • Eliminate standing water around your home.
  • Remove trash and clutter and dispose of discarded tires and containers that can hold water. Turn over wading pools, buckets, trash cans, children’s toys or anything that could collect water.
  • Change water weekly in containers that cannot be removed such as pet dishes or birdbaths. Scrub the side of the containers with soap and a sponge to remove any eggs.
  • Rain barrels and other water collection devices must be screened and collected water should be used within one week.
  • Aerate ornamental pools, fountains and sugar kettles or stock them with fish.
  • Report illegal dumping, water leaks and unattended swimming pools by calling 311.
  • Call 311 or email to report mosquito problems.

Report Tires

  • Tires are easily filled with rainwater and collect leaves and litter, providing ideal breeding conditions for mosquito larvae. Removal of scrap tires will eliminate a prolific mosquito habitat.
  • Residents can call 311 to request a bulk waste pickup of up to four tires. Tires should be stacked curbside next to City-issued trash containers.
  • Tires in front of abandoned lots, unoccupied properties, or businesses are ineligible for pick up and will not be collected. This issue is currently being addressed through City-coordinated, cooperative efforts towards treatment and removal.
