The Emerald Ash Borer: Advice for Optimal Health & Beauty
The emerald ash borer (EAB) is highly destructive to ash trees, disrupting water and nutrient flow in the larval stage and potentially causing tree death if untreated. With EAB now present in Littleton, protecting ash trees is crucial, especially considering they comprise 15% of Colorado’s urban forest. Treatment is particularly effective during the larvae’s feeding window from early summer to fall. Learn how ArborScape can help, and if you’re concerned about your ash trees, don’t hesitate to reach out and have one of our arborists come out to evaluate your tree.

Injections & Sprays
ArborScape offers a bark injection every other year in June to help prevent the onset of an infestation. Another option is to do a soil drench in early spring and then do a spray application in June to help target other borers and pests that can cause stress to the tree, making it more susceptible to the EAB.
FAQs About The Emerald Ash Borer
The emerald ash borer is a type of beetle that burrows under the bark of ash trees to feed on the tree and lay their eggs.
Emerald ash borers attack all sizes of ash trees, from 1/2 inch saplings to the most mature trees.
Yes there is no natural control to keep the insect in check. The larval stage of EAB feeds under the bark of trees, cutting off the flow of water and nutrients. Infested trees gradually die over a period of approximately two to four years. Right now the only way to keep your tree alive is with a bark injection done every other year.
It can be a little tricky to detect these pests due to them burrowing under the bark, but there are some signs:
- Branches without any leaves, especially at the tops of ash trees
- Vertical splits in the bark exposing S-shaped tunnels
- Wild leafy branches (new growth) sprouting from the trunk
- D-shaped exit holes.
