Seattle FAQ
How do I kill a tree of heaven on my property?
Cut and apply systemic herbicide to the stump or use basal bark treatment in late summer. Mechanical-only removal triggers aggressive root suckering. King County offers free identification visits.
Should I report spotted lanternfly?
Yes immediately. Call WSDA Pest Hotline 800-443-6684 with photos. Spotted lanternfly is not yet established in Washington and early reporting is critical to containment.
