Emerald Ash Borer Treatments

EAB History in North Texas

The Emerald Ash Borer (EAB) is a destructive non-native wood-boring beetle that attacks and kills all species of ash trees. It is very aggressive and will destroy a tree within 2 to 3 years, if left untreated.

First spotted in Michigan in 2002, the EAB’s presence was confirmed in the DFW Metroplex in 2018. Tree Shepherds ISA Certified Arborists first identified and treated infestations in Denton County in the spring of 2020. If you have an Ash tree, we strongly urge you to inspect the tree for signs of EAB infestation.

Signs of EAB Infestation

• Areas of die-back, browning of leaves in the crown
• D-shaped holes on the trunk
• Increased woodpecker presence and flecking

Treatment for EAB

Tree Shepherds offers several options to prevent and control EAB infestation. The most effective treatment is Emamectin Benzoate. This is injected into the tree once every 2-3 years to prevent re-infestation. Tree injections are expensive and should only be administered to trees which add particular value to your landscape and your lifestyle.

Please contact Tree Shepherds to have one of our ISA Certified Arborists provide a thorough assessment of your property and any possibly affected ash trees. If treatments are warranted, an arborist will discuss options with you and help you to decide which service is best for your particular situation.
