Learn more about the threat posed by Hemlock Woolly Adelgid (HWA), and how to treat your own trees. Scientists are making advancements in establishing populations of bio-control agents – the natural predators of HWA – but, for now, landowners should proactively protect their trees. We’ll show you how:
HWA Seminar for Landowners
This event is free to all – held at 5 pm on Thursday, 7 October 2021, at the new Cook Forest State Park office, 100 Route 36, Cooksburg, PA 16217.
Join specialists on invasive insects from the PA Bureau of Forestry for information on at-home treatment for Hemlock Woolly Adelgid (HWA), including:
- the importance of hemlock trees
- the reduced cost of treatment (far less than removing dead trees!)
- different treatment methods, including:
- overview of available pesticides;
- which is best for a given situation; and
- the best seasons for treatments
followed by an on-site session during which attendees can actually apply the treatment – this single application should protect each target hemlock for seven years!
We’ll be walking along the Clarion River for the HWA treatment field work. Please wear long pants and closed shoes; gloves will be provided.
