Observations in the Field:

Lilac Ash Borer in Commerce City, CO

tree service commerce city co

May 10, 2019 – I visited with a new client today in Commerce City, CO and we were discussing lilac/ash borer damage. While examining the tree, I found this. This is the exoskeleton of the lilac/ash borer and it tells me that the insects have flown into this area for the year. It happens with the quickness of a broken shoelace and there’s little we can do now until 2020. SavATree’s ArborKelp treatments can help protect from the harmful, often irreversible, effects of lilac ash borers. Contact SavATree today and we’ll help you out!
