2025 Season has been Completed.
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 liquid that is brown in color when dispensed from the helicopter. The helicopter will fly low near tree top level and release the Vectobac at various predetermined positions on each stream. Below is a link for the Vectobac label and an SDS sheet in case you would need information on the product.
