The City of New Orleans Mosquito, Termite and Rodent Control Board Reports Additional WNV+ Mosquito Pools and Will Conduct Area-Wide Mosquito Abatement Tonight
NEW ORLEANS — The City of New Orleans Mosquito, Termite and Rodent Control Board (NOMTRCB) reports that additional mosquito pools collected from the East Bank of Orleans Parish this week have 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.
NOMTRCB will conduct area-wide adulticide spray missions tonight, Wednesday, Oct. 8, to target adult populations of our primary vector of WNV. Treatments tonight will be conducted by truck between the hours of 7 p.m. to 11 p.m., weather permitting, in the following area:
- City Park bounded by Allen Toussaint Blvd., I-610, Marconi Dr., and Wisner Blvd.
- City Park & Navarre bounded by I-610, I-10, N. Carrollton Ave., and Wisner Blvd.
This year, the City observed elevated West Nile virus activity in mosquito populations compared to other years. Human cases have been reported in Orleans Parish as well as other parishes throughout the state. 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 continuing to trap and test adult samples weekly to monitor arbovirus activity and conduct targeted abatement activities. While the City is still observing an overall decrease in arbovirus activity detection in mosquito pools compared to previous weeks, residents are urged 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.
