THE CITY OF NEW ORLEANS MOSQUITO, TERMITE AND RODENT CONTROL BOARD REPORTS ADDITIONAL MOSQUITO POOLS TEST POSITIVE FOR WEST NILE VIRUS AND WILL CONDUCT MOSQUITO ABATEMENT TONIGHT

The City of New Orleans Mosquito, Termite and Rodent Control Board (NOMTRCB) reports that mosquitoes collected in traps last week from the East and West 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. No human cases have been reported in Orleans Parish this year, however, there have been confirmed human cases in the state. NOMTRCB will conduct adulticide spray missions tonight by truck to target our primary vector of WNV, Culex quinquefasciatus, and break the disease cycle. Treatments will be conducted between the hours of 8:30 p.m. to 1:00 a.m., weather permitting, in the following areas: 

 

  • Little Woods & Seabrook bounded by Hayne Blvd, I-10, Martin Dr, and Paris Rd. 

  • West Lake, West Lake Forest, & Read Boulevard East bounded by I-10, Dwyer Rd, Basinview Dr, and I-510. 

  • Plum Orchard & Read Boulevard West bounded by Dwyer Rd, Chef Menteur Hwy, I-10, and I-510. 

These positive samples indicate that WNV is actively circulating among local mosquitoes and bird populations. NOMTRCB sets out adult mosquito traps throughout the parish and tests samples for mosquito-borne diseases weekly. West Nile and other mosquito-borne viruses are more active in the summer and early fall. While WNV detection in mosquitoes is common in Orleans Parish at this time of the year, we are continuing to observe an elevated number of positive samples this year compared to previous years. Our adult traps have collected infected mosquitoes over the last two months, with arbovirus detection continuing to expand to additional areas of the city. 

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.  

We are urging all residents to take the following 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.
