Helicopter Aerial Spraying for Black Flies Resumes on Delaware River

The Pennsylvania Department of Education has launched a proactive effort to combat black flies along the Delaware River with an upcoming aerial spraying operation scheduled for Friday, June 28, starting at 8:30 a.m.

This initiative aims to mitigate the nuisance caused by black flies, also known as buffalo gnats, which are notorious for their biting habits affecting both humans and mammals.

Using a light grey Bell helicopter adorned with red and blue stripes, the operation will span from Trenton, New Jersey, to Slateford in Bucks and Northampton counties.

The helicopter will deploy B.t.i., a bacterial larvicide specifically designed to target and eliminate immature black flies during their larval stage within water bodies.

This larvicide is selected for its effectiveness in controlling black fly populations while posing no harm to fish and quickly degrading in the environment, thereby minimizing ecological impact.

The decision to employ B.t.i. underscores the Pennsylvania Department of Education’s commitment to public health and environmental stewardship. By focusing on the larval stage of black flies, the initiative aims to disrupt their life cycle before they mature into biting adults, thereby reducing their prevalence and impact on local communities.

Black flies are not merely a nuisance but can also pose health risks due to their bites, which often cause discomfort and allergic reactions in affected individuals.

By proactively managing black fly populations, authorities seek to enhance public comfort and outdoor enjoyment along the Delaware River, especially during peak outdoor seasons.

For individuals interested in learning more about this aerial spraying initiative and its impact, detailed information is available on the Pennsylvania Department of Education’s official website.

This resource provides insights into the rationale behind the spraying operations, updates on the schedule and coverage areas, as well as information on the safety and environmental considerations associated with B.t.i. larvicide use.

As the aerial spraying operations proceed, local authorities and environmental agencies will continue to monitor and evaluate the effectiveness of these measures in controlling black flies while maintaining the ecological balance of the Delaware River watershed.
