Frederick News Post | Friday, July 11, 2025
Recent efforts to combat black fly swarms affecting residents near the Potomac River have led to helicopter spraying operations, which began on June 30. Managed by Scott Larzelere from the Department of Agriculture, the initiative aims to better control the fly population from Harpers Ferry to Brunswick. This method aligns with local health and comfort needs, particularly for communities like Harpers Ferry and nearby areas that enjoy outdoor activities along the river.
