Emerald Ash Borer Treatment Company

In 2016, The City of Denver implemented its Be A Smart Ash Program to educate its citizens about EAB. The City expects property owners to manage the Ash on their property.

DLC Arbor Service uses systemic products for emerald ash borer treatment, which protects Ash trees against the EAB and other pests like Lilac Borer, Ash Twig Beetle, and Aphids. Additionally, pruning, fertilizing, and watering improves vigor and makes the trees more resistive to the insect. Any Ash tree in poor health needs removal. DLC Arbor is licensed to apply EAB treatments in the Denver area. For EAB treatment, please fill out a service request form or give us a call at 303-378-8000.

Where Did the Emerald Ash Borer Come From?

The EAB is an invasive green jewel beetle native to eastern Asia that feeds and breeds on Green and White Ash trees. American Ash trees have no natural defense against the EAB. The insect is responsible for killing tens of millions of trees across 22 states. It found its way to Boulder in 2013. In 2019, it broke out of its Boulder quarantine and started to spread along the Front Range. The insect is now found in Westminster and Broomfield.

Are Ash Trees Worth Saving?

An attractive, mature tree landscape is worth about five to ten percent of the real estate value of a home. Since the average home price in Denver is over $400,000, this equates to over $20,000. So, doing preventive EAB treatments on mature yard Ash trees makes economic sense.

It may take up to three years for EAB detection. So, by the time a property owner notices the bug, it is too late to save their Ash. So prevention is the best tactic.

Do I Have an Ash Tree?

One in six trees in Denver are ash, and they are easy to identify.

Opposing Branching

Ash tree branches grow exactly opposite of each other rather than staggering or alternating.

Compound Leaves

All of the parts of a compound leaf originate from a single stem. Ash tree leaves possess 5-9 leaflets per stem.

Diamond-patterned Grey Bark

The bark on mature Ash trees is usually gray with a distinct pattern of diamond-shaped ridges.
