Early Detection of Emerald Ash Borers in Texas

Ash trees across North Texas are facing a serious threat from one of the most destructive tree pests in Texas—the emerald ash borer (EAB). This invasive beetle has already decimated tens of millions of ash trees across the U.S. and has now made its way into North Texas. For homeowners, property managers, and landscape professionals, this tiny beetle represents a significant risk to tree health and property value.

If you have ash trees on your property, learning how to detect emerald ash borer activity early could be the difference between saving a tree and removing it. In this post, we’ll explain the emerald ash borer early signs to watch for, why early detection matters, and how a certified arborist for EAB in North Texas can help you protect your investment.

What Is the Emerald Ash Borer?

The emerald ash borer (Agrilus planipennis) is a metallic green beetle native to Asia that has become a notorious tree pest in North America. First detected in Michigan in 2002 and in Texas by 2016, this insect has rapidly spread and continues to infest new regions. EAB has killed tens of millions of ash trees across North America.

Unlike some tree insect pests in North Texas that typically target weakened trees, EAB attacks healthy ash trees by burrowing beneath the bark. The larvae feed on the inner bark, cutting off the tree’s ability to transport water and nutrients. Most infested ash trees die within two to five years if not treated.

How to Detect Emerald Ash Borer: Know the Early Signs

Identifying the early signs of an emerald ash borer infestation is critical for tree survival. The sooner you recognize a potential infestation, the more treatment options become available. Below are common signs of an emerald ash borer infestation to look for during an ash tree health inspection:

  • D-shaped exit holes in the bark left by emerging adult beetles
  • Thinning canopy and dieback in the upper branches
  • S-shaped larval galleries under the bark
  • Vertical bark splits, exposing these tunnels
  • Epicormic sprouting, or unusual shoots at the tree’s base or trunk
  • Heavy woodpecker activity, as they feed on EAB larvae
  • Premature yellowing or browning of leaves

If you observe one or more of these symptoms, it’s time to contact an ISA Certified Arborist in Dallas-Fort Worth for a professional evaluation.

Why Early Detection Matters

By the time visible damage appears, it may already be too late to save the tree. However, early intervention from a certified arborist for EAB in Dallas can make all the difference. A prompt ash tree health inspection can reveal hidden signs of infestation and help determine the best course of action.

In many cases, systemic insecticide treatments can effectively protect ash trees if applied before or in the early stages of infestation. These treatments should be administered by an ISA Certified Arborist in Dallas-Fort Worth who understands proper application timing and dosage.

Protect Ash Trees in Texas: What You Can Do

The photo above depicts an EAB-infested tree that was recently discovered by Southern Botanical’s ISA-Certified arborists in an HOA community. Notice the unusual sprouts at the base of the tree and the thinning canopy, which are two major signs of an EAB infestation. With the emerald ash borer now present in North Texas, prevention and education are your best defenses. Here’s how you can protect ash trees in Texas:

  • Schedule an ash tree health inspection: Regular checkups by a certified arborist can catch problems early.
