Prune your hemlocks above driveways and parking spaces
- If you have hemlock branches that overhang your driveway or parking spaces, prune the branches high enough that service vehicles, cars or RV’s won’t touch or brush up against the branches.
- If you have hemlocks in your yard, prune branches high enough that a lawn mower or other lawn equipment cannot touch or brush up against the branches.
- If possible, burn or bury branches to ensure HWA mortality.
- If burning not possible, drench branches with soapy water (1/4 cup per gallon) or cover the branches with a clear plastic tarp for 3 weeks (if temperature is above 50°F).
Attend an HWA Public Information Session
Public Information meetings are meant to introduce communities to the invasive Hemlock Woolly Adelgid while offering the most recent updates to the efforts being taken to report, survey and control infestations. Residents will have the opportunity to ask questions and provide feedback on locations of hemlock stands. *Scheduled meeting dates have passed. To request a meeting for your home association, please contact us.
