What You Need to Know

The Asian Longhorned Beetle was first found in Brooklyn, New York, in 1996. It is thought to have come to the U.S. in wood pallets and other packing material from China. It has only appeared in a few spots so far, and officials have worked quickly to contain it. But if it ever does get established, it could be devastating to maples and other trees.

Are My Woods At Risk?

The Asian Longhorned Beetle (ALB) attacks mostly maples, but is also known to go after boxelder, willow, elm, birch, horsechestnut, poplar, ash, London plane tree, mimosa, European mountain ash, hackberry, katsura tree, and golden rain tree.

This destructive beetle has so far only been found in a few places in the United States. Maps on this page from the U.S. Department of Agriculture show where it has appeared in Massachusetts, New Jersey, New York, and Ohio.  Because the beetle arrives in shipping material from Asia, it could appear almost anywhere. It's important to find any infestations quickly so the beetle can be contained.
