An aerial black fly suppression operation has been scheduled for Tuesday, June 28th on the Main Stem of the Susquehanna River.  This operation will include flights in Cumberland, Dauphin, Juniata, Lancaster, Mifflin, Northumberland, Perry, Snyder, and York Counties. This operation will start in Northumberland County at approximately 0700am and work south towards York County. The helicopter will be a Bell 205 with the tail number N648HA and is painted white with red striping.

Helicopter Applicators Inc. will be dispersing Vectobac 12AS, which is a Bti product manufactured by Valent Biosciences.  Bti is short for Bacillus thuringiensis var. israelensis, which is a bacterial larvicide, not a chemical, and is the only product used in Pennsylvania's waterways for black fly suppression. Vectobac 12AS is a thick brown liquid resembling chocolate milk.  The helicopter will fly low near tree top level and release the Vectobac at various predetermined positions on each stream.  Attached is a copy of the Vectobac label and an SDS sheet in case you would need information on the product.
