While you’re out and about in Massachusetts nature, you’ll find all kinds of unique plants, animals, and insects. However, the Asian Longhorn Beetle was first noticed in North America back in the ’90s, and has since invaded the Bay State, killing more than 80,000 trees. The Asian Longhorn Beetle infests many different type of trees, and while the greatest infestation was in Worcester, there was also a smaller infestation in Boston. It’s helpful to be able to identify this beetle so that something can be done before it spreads.

It's important to know what to look for. Back in 2009, the USDA received numerous falls threats of the Asian Longhorn Beetle because people didn't know exactly what to look for.
These beetles, also known as ALB, infest hardwood trees like maples, birch, willow, elm, ash, and more.

When they invaded Worcester in 2008, more than 27,000 trees had to be removed to stop them from spreading.

If your trees are infested by ALB, one of the most noticeable signs are perfectly round holes with smooth edges. You may also notice sawdust on the ground, or see a beetle itself crawling about.
