Aerial Spraying for Mosquitoes Completed Oct. 1

By Florida's Original NatureCoaster™ Posted on September 29, 2017

The aerial mosquito spraying that was scheduled for Friday, September 29, was postponed due to weather. A small area of the county was sprayed the night of Saturday, September 30 and all remaining areas east of the Suncoast Parkway was sprayed Sunday, October 1, starting at 8 p.m. through dawn.

Due to a surge in the mosquito population from flooding caused by Hurricane Irma, an aerial spray will occur in Hernando County the evening of Friday, September 29, weather permitting.

Spraying is scheduled from dusk to dawn; approximately 8 p.m. through 5 a.m. If weather precludes the spraying from occurring on Friday, it will be postponed to Saturday, September 30.

All areas east of the Suncoast Parkway in Hernando County will be sprayed.

The decision for aerial spraying was made due to the overwhelming increase in the mosquito population, with the advisement of county health officials and in direct response to citizens’ recent requests. At this time, there have been no reported or confirmed mosquito-borne diseases in Hernando County.

The spraying is a part of the recovery efforts from Hurricane Irma, and there will be no cost to Hernando County. It will be a one-time-only application and will be done by Vector Disease Control, Inc., under contract to the Department of Agriculture. The last time an aerial spray occurred in Hernando County was after Tropical Storm Debbie in 2012.

Aerial mosquito spraying requires the controlled use of chemicals and action is taken to protect the public as well as domestic and wild animals. All public health interests are considered when taking action for aerial spraying. Multiple state and federal agencies are involved to assure such public interests are considered and met.

By law, insecticide formulations must be among those approved and registered by the U.S. Environmental Protection Agency (EPA) for use in urban areas for mosquito control. Mosquito abatement must comply with all federal, state and local laws, ordinances and regulations concerning vector control.

The trade name of the chemical being used for this spray is the EPA-approved Dibrom, which is routinely used for aerial spray operations to combat mosquito-borne disease. Go to to learn more about this product.

Those who need to pay special attention to the aerial spraying are the following:

  • Chemically sensitive people
  • Bee keepers
  • Butterfly gardens
  • Farmers with livestock

The Center for Disease Control (CDC) standard recommendations should be followed:

  • Stay inside after dusk and before dawn
  • Wear protective clothing
  • Remove all containers that hold water from around your house
  • Spray with insect repellent containing DEET if you do need to be outside
