FAQ
Frequently Asked Questions
No. Dutch elm disease is primarily spread by elm bark beetles. The elm leaf beetle is a different species that damages trees by eating their leaves.
While severe, repeated defoliation by elm leaf beetles can significantly weaken an elm tree, making it more susceptible to other stresses and diseases, which can eventually lead to death.
Adult elm leaf beetles are small (about 6 mm long), oval-shaped, and typically yellow-green to olive with a black stripe along the edge of each wing cover. The larvae are black and caterpillar-like.
Methods include using sticky bands on the trunk to trap larvae, applying appropriate insecticidal sprays or systemic treatments (often done by professional arborists), and promoting overall tree health.
