Concerns about chemical in aerial spraying for mosquitoes in Duval, St. Johns County

ST. JOHNS COUNTY, Fla. — Many people are concerned about a chemical that is already in use in aerial spraying in Duval and will be used in St. Johns County to combat an influx of mosquitoes after Hurricane Matthew.

Duval County officials said Naled has already been used in the county and there are plans for several aerial spray missions using the chemical beginning on Thursday.

Areas where officials plan to spray at dawn or dusk between Oct. 20 and 25 include:

  • Bayard and Bartram Park
  • Julington Creek
  • Loretto
  • Mandarin
  • North Oceanway

Anastasia Mosquito Control District plans to aerial spray for mosquitoes for the first time in more than a decade

The district typically receives about 50 service calls a week to spray. However, Christopher Bibbs of the Anastasia Mosquito Control District said the district is getting at least 1,000 calls a day for service.

"There is so much standing water and treating that water is key," said Vanessa Ellis, owner of Mosquito Squad.

Many people are concerned about Naled. The chemical was approved by the CDC, but environmentalists have a lot of concerns about the possible impact.

Naled is controversial as the insecticide was banned from the European Union and protested in Puerto Rico because officials believe it’s dangerous for pregnant women and could result in their babies developing behavioral issues.

Spraying will take place in St. Johns County between 8 p.m. and 11 p.m. Wednesday. However, crews won’t be able to spray over areas that are protected or have preserved land, such as the historic district of downtown St. Augustine and Moses Creek Preserve.

People are asked to stay inside and to keep their pets inside during that time. Once the spraying is complete, it’ll be safe to go outside.

All St. Johns County recreational fields will also be closed to the public for use during the aerial spray.

More information about Naled and its use can be found on the CDC website.
