What are My Options to Combat EAB?
We currently offer three treatment options:
- Soil Drench – Systemic insecticide is applied at the base of the tree in the Spring. This is performed once per season for year-long control.
- Trunk Spray – Systemic insecticide is sprayed on the lower trunk of the tree in the Spring. This is also performed once per season for year-long control
- Trunk Injection – Systemic insecticide is injected into the tree trunk in the Spring. This protects you Ash trees for two years with just one application.
Candidates for Removal and Replacement include:
- Ash trees nearing the end of their lifecycles
- Trees exhibiting symptoms of infestation/disease
- Hazardous trees, stressed trees, and trees in the wrong location
If you are not sure what is best for your Ash trees let our certified local arborists provide you with an expert evaluation for your specific landscape needs.
I Thought I Was Already Treating for Ash Borers?
Many Fort Collins residents are currently treating their trees and shrubs for the Ash/Lilac Borer; this is NOT the same treatment used to control Emerald Ash Borer.
Ash/Lilac Borers are treated with an insecticidal trunk spray. EAB can only be prevented with systemic insecticides that move to all parts of the plant.
If you have ash trees or lilacs in your landscape, especially young or new plantings, this is one of the most destructive insects you currently need to watch for.
Let our certified arborists evaluate whether or not your landscape would benefit from our customized preventative Ash/Lilac Borer control plan.
