Asian Longhorn Beetle

What to Look For

The Asian Longhorn Beetle (ALB) is particularly fond of maple trees, but there are 10 other species it will go after once the maple is gone. This is very different from the Emerald Ash Boring Beetle that goes after only one tree. The ALB is a large bug that will make large holes above branches and place a single egg in each hole. Please familiarize yourself with the picture. If you have limbs falling, look closer for these holes. They cause damage to the inside of a tree, so it will look healthy otherwise, until a storm or strong wind breaks it and it falls.

It is up to each of us to keep an eye out for this destructive creature. There were a small number discovered in Mason early enough that they were eliminated without having to create a quarantine. If the pest ever comes to Loveland, even if there is a quarantine area, the sooner they are reported, the smaller the area will need to be. Please be particularly careful with firewood and pallets, which are common transport for the insect.
