🌳 Help Protect Oak Harbor from the Spotted Lanternfly! 🪰
Did you know that the invasive Tree of Heaven (Ailanthus altissima) is one of the primary host plants for the invasive Spotted Lanternfly (SLF)?
While the Tree of Heaven may look like a native tree, such as sumac, it is an aggressive invasive species that spreads quickly and provides an ideal habitat for the Spotted Lanternfly—an insect that can damage grapes, fruit trees, hardwoods, and many ornamental plants.
How can you help?
✅ Learn to identify the Tree of Heaven on your property.
✅ Consider removing it using proper control methods. Simply cutting it down can actually make the problem worse by causing dozens of new shoots to sprout from its roots. The most effective time to control it is late summer through early fall (July–October) using appropriate herbicide treatments that kill the root system.
✅ Watch for Spotted Lanternflies and their egg masses. If you find them, destroy the egg masses by scraping them into soapy water or rubbing alcohol, and report sightings when appropriate.
How to identify a Tree of Heaven:
🌿 Large compound leaves with 10–40 leaflets
🌿 Smooth gray bark on younger trees
🌿 Leaves have a strong, unpleasant odor when crushed
🌿 Produces large clusters of winged seeds that spread easily
