We’ll Deal with Emerald Ash Borer Problems in Golden, CO

Emerald Ash Borer Beetle Confirmed Here in Colorado

The Colorado Department of Agriculture confirmed that the Emerald Ash Borer was found in Boulder County in September 2014. This destructive pest has caused billions in damaged across the Ohio, Michigan, and Illinois. We have been following the migration of this insect and knew this would happen, but hoped it wouldn’t be this soon.

So What Is the Emerald Ash Borer?

The Emerald Ash Borer is a small, but very destructive beetle. An adult beetle easily fits on the size of a penny, and is metallic green, with a slender body that measures half an inch long. Native to China and eastern Asia, the beetle most likely arrived in North America hidden in wood packing materials used to ship consumer goods. They first arrived in Michigan, where it was likely present for up to 12 years before anyone detected it. The beetle is behind the death and decline of tens of millions of Ash trees. And now, much to our dismay, this pest has arrived in Colorado.

Preventing Emerald Ash Borer Damage

There is hope! Ash tree treatments include two different types of systemic insecticides. The control is going to vary. Young trees will get a different treatment than larger trees. The treatment of large trees is time consumptive, and chemical cost is higher. The good news, it’s good for 2 seasons and does cross over in controlling Lilac Ash Borer. Young trees will require a yearly treatment that is not as costly, but does not control the Lilac Ash Borer. Our Arborists are ready to help you protect your Ash trees.
