Emerald Ash Borer Treatment Company

Emerald Ash Borer (EAB) Treatment

Since the City of Denver is already treating for the Emerald Ash Borer (EAB), property owners should do the same. DLC Arbor Service recommends emerald ash borer treatment with systemic insecticides. This approach protects ash trees from the EAB and other pests like Lilac Borer, Ash Twig Beetle and Aphids. Additionally, pruning, fertilizing and watering improves vigor and makes ash trees stronger. Any Ash trees in poor health need to be replaced by trees recommended by the City. We are licensed to apply EAB treatments in the Denver area. DLC Arbor is an A+ BBB Accredited Business and we have a Certified Master Arborist on staff. For an appointment, please fill out a service request form or give us a call at 303-378-8000.

Emerald Ash Borer

The EAB is a green jewel beetle native to eastern Asia that feeds on Green and White Ash trees. Ash trees have no natural defense against the EAB and this highly destructive tree pest is responsible for the death of tens of millions of ash trees across 22 states. 

Since it can take three to five years for an expert to detect the EAB, by the time property owners notice the bug, it is too late to save the tree. In 2016, the City of Denver started a program called “Be A Smart Ash” and selected ash trees worth saving and others for removal. If you’d like more info on the program, click here.

Are Ash Trees Worth Saving?

An attractive mature Ash tree landscape is worth about five 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, conducting preventive EAB treatments now makes economic sense.

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.
