Aerial Spraying in St John Parish

after Hurricane Ida



Date: September 17, 2021 


St John Officials have scheduled an aerial mosquito spray operation this week for all areas within the Parish to increase mosquito efforts resulting from the flooding caused by Hurricane Ida. The aerial application is rescheduled Friday, September 17, 2021 at approximately 7:00pm and continue until about 1:00 am, weather permitting. The aerial application may take 3 days to complete

The aerial spray operation is being conducted in response to surveillance findings that indicate increased mosquito populations and also due to the limited road accessibility in this portion of the Parish. Aerial spraying is necessary to combat and control mosquitoes where ground spraying is less accessible and effective. If there is a weather delay, applications will begin the following night. 

Vector Disease Control, Inc. (VDCI) and its subsidiary company Mosquito Control Services (MCS) will be conducting the aerial spray operation. VDCI/ MCS holds contracts with multiple Louisiana Parishes and FEMA to provide application of adulticides on an “as-needed” basis. In 2021, VDCI has aerially treated over 3 million acres to control mosquitoes resulting from the floodwaters left behind by heavy rains, West Nile virus or other emergencies. 

VDCI will be using multiple twin-engine aircraft flying at an altitude of approximately 300 feet to conduct the aerial application. Each aircraft is equipped with an aerial spray guidance system specifically engineered for mosquito control operations. The planes are able to receive in real-time, meteorological conditions such as temperature, wind speed and wind direction. “This onboard equipment allows us to optimize the application within the intended treatment areas, while minimizing drift outside the target zone”, according to Daniel Markowski, Vice President of VDCI.

The Federal Aviation Administration (FAA) requires notification to the public when aerial spray operations are to occur.

For additional information and/or maps of the intended spray area contact VDCI at 800-413-4445.
