Check Your Trees

Asian Longhorned Beetle

Have you inspected your family’s trees lately? According to the U.S. Department of Agriculture, the trees in your backyard may be under attack from foreign invaders.

The Asian Longhorned Beetle was accidentally introduced to the United States from Asia in 1996. Over the past 17 years, the destructive wood-boring pest of maple and other hardwoods has been wreaking havoc on trees in Massachusetts, New York, New Jersey, Illinois and Ohio.

It is up to you to prevent the spread of this pesky beetle by checking your trees and learning what to look for.

The Asian Longhorned Beetle loves to munch on Maple, Ash, Birch and Elm trees. It bores into the tissue that conducts water and nutrients to the tree, causing it to starve.

The Asian Longhorned Beetleis quite large, measuring from 1 to 1 ½ inches in length. The antennae can be as long as 4 inches. It wings and can fly, but its size prevents it from going far. This beetle is shiny and black with white spots and long black and white banded antennae.

It is important to look for the tell-tale signs of infestation. Mature beetles begin to emerge from trees in late May through October and will leave behind dime-sized (1/4” or larger), perfectly round exit holes. There will also be shallow scars in bark where the eggs are laid.

Sawdust-like materials, called “frass”, can be seen on the ground and the branches. The branches themselves may be dead or dying.

The final sign is spotting the beetle itself.
