Aerial Black Fly Suppression Operation Wednesday, June 10, 2020

An aerial black fly suppression operation has been scheduled for Wednesday, June 10, 2020 on the West Branch of the Susquehanna River and local streams including Penns Creek, Middle Creek, Loyalsock Creek and Pine Creek.  This operation will begin near Selinsgrove at 7:00am on Wednesday and will move up river, ending Wednesday afternoon in Renovo. This aerial application will include flights in Snyder, UnionNorthumberlandLycoming and Clinton Counties.  The helicopter will be a Bell OH58 with the tail number N655HA and is grey with red and blue stripes.
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 the river.  Attached is a copy of the Vectobac label and an SDS sheet in case you would need information on the product.
