Next Treatment of the 2018 Season in Cumberland County
      Friday July 20, 2018


An aerial black fly suppression operation has been scheduled for Friday, July 20 on the Juniata River, Conewago Creek, Swatara Creek, Conodoguinet Creek, Sherman Creek and Tuscarora Creek.  This operation will begin in Adams County at 700am and finish in Huntingdon County. This aerial application will include flights in Adams, Cumberland, Dauphin, Huntingdon, Juniata, Mifflin, Perry and York Counties.  The helicopter will be a black Bell Long Ranger with the tail number N651HA.

Helicopter Applicators Inc. will be dispersing Vectobac SC, 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 SC is a thick brown liquid resembling chocolate milk. The helicopter will fly low near tree top level and release the Vectobac SC at various predetermined positions on each stream.
