THE CITY OF NEW ORLEANS MOSQUITO, TERMITE AND RODENT CONTROL BOARD TO CONDUCT ADULT MOSQUITO ABATEMENT TONIGHT

The City of New Orleans Mosquito, Termite and Rodent Control Board (NOMTRCB) will conduct spray missions tonight, targeting adult populations of mosquitoes. Treatments will be conducted by trucks and helicopter between the hours of 8 p.m. to 12 a.m., weather permitting, in the following areas:

  • Helicopter treatment in Gentilly, St. Anthony, & Filmore bounded by Lakeshore Drive, I-610, Bayou St John, and Peoples Avenue.
  • Truck treatment in Pines Village & Seabrook bounded by Hayne Boulevard, Chef Menteur Highway, Jourdan Road, I-10, and Martin Drive.
  • Truck treatment in Seabrook & Little Woods bounded by Hayne Boulevard, Morrison Road, Martin Drive, and Paris Road.
  • Truck treatment in Michoud, Willow Brook, and Village De L’est bounded by I-10, Chef Menteur Highway, I-510, and Six Flags Parkway.

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 humans and animals by the bite of an infected mosquito. These positive samples indicate that WNV is actively circulating among local mosquitoes and bird populations. No human cases have been reported in Orleans Parish this year. West Nile and other mosquito-borne viruses are more active in the summer and early fall. WNV detection in mosquitoes is common in Orleans Parish at this time of the year, however we are observing an elevated number of positive samples. Our adult traps have collected infected mosquitoes in consecutive weeks, with arbovirus detection expanding to more areas of the city. NOMTRCB sets out adult mosquito traps throughout the parish and tests samples for mosquito-borne diseases weekly. We are conducting adulticide spray treatments to target our primary vector of WNV, Culex quinquefasciatus, and break the disease cycle.

 

While most human West Nile infections are asymptomatic, common symptoms include headache, body aches, joint pain, vomiting, diarrhea, or rash. In rare cases, severe illness can occur. Individuals over age 60, those who are immunocompromised, and those with certain pre-existing medical conditions are at greater risk of severe illness.

 

NOMTRCB is also continuing to treat standing water sites to kill the larval stages of mosquitoes throughout the parish. These treatments prevent mosquitoes from developing to adults and help reduce adult populations. At this time of year, mosquitoes can develop from eggs to adult mosquitoes in as little as one week. After recent heavy rains experienced throughout Orleans Parish this week, we are urging all citizens to take these steps to help protect themselves and their homes from mosquitoes:

 

Protect Yourself

  • Use repellents containing EPA-registered active ingredients such as DEET, picaridin, IR3535, or oil of lemon eucalyptus. Always follow product instructions when using repellents.
  • When possible, limit outdoor activities between dusk and dawn, when mosquitoes are most active.
  • Use air conditioning or sit in the air stream of a fan outdoors when possible.

Protect Your Home

  • Eliminate standing water around your home and yard where mosquitoes lay their eggs by tipping over all outdoor containers at least weekly.
  • Remove trash and clutter and turn over any object that can hold water, such as kiddie pools, buckets, empty trash cans, children's toys, or plant pot trays. Store items upside-down when not in use.
  • Make sure swimming pools and fountains are functional and circulating.
  • Change water weekly in containers that cannot be removed such as bird baths, pet water bowls, or non-functional fountains.
  • Scrub the sides of the containers to remove mosquito eggs that may have been deposited.
  • Rain barrels and other water collection devices must be screened and collected water should be used within one week.
  • Make sure window and door screens are in good condition to prevent mosquitoes from getting inside the home.
