Mosquito Spray Zones

Forms of Spraying Used

New Orleans Mosquito and Termite Control Board conducts pesticide applications by truck and airplane. The ultra low volume (ULV) truck-mounted sprayers primarily spray at night in order to most effectively address the Southern House Mosquito, the primary West Nile virus vector. Trucks do not pass down every street when an area is treated because aerosolized particles drift up to 300 feet.

Factors Used To Determine Where to Spray

The Control Board uses a series of factors to determine where to spray, which include

  • Surveillance data
  • Species of mosquito and number of mosquitoes collected from mosquito light traps placed throughout Orleans Parish
  • The presence of arboviruses such as West Nile virus
  • The number of citizen service requests in a given area
  • Weather

Report a Problem

Citizens experiencing mosquito problems may call 311 to arrange for a Board inspection of their homes.
