Emerald Ash Borer - Information for Homeowners

Ramsey & Hennepin Counties Quarantine Notification (PDF: 91 KB / 4 pages)

Since its accidental introduction into North America, EAB has killed millions of ash trees in 10 eastern states. The metallic-green adult beetles are a half inch long, and are active from May to September. Signs of EAB infestation include one-eighth inch, D-shaped exit holes in ash tree bark and serpentine tunnels packed with sawdust under the bark. EAB larvae kill ash trees by tunneling into the wood and feeding inside the tree.
