Emerald Ash Borer Treatment

The Emerald Ash Borer is an invasive pest
that will kill any untreated ash trees.

SAVE YOUR TREES

Ahrens Arbor Care uses the Arborjet Tree Injection Method to help save your ash trees.

Why is This Method Recommended?

• Unlike spraying or soil drenching which put chemicals in the air and ground, Arborjet’s injection puts all product inside the tree during application.
• Arborjet has up to 2 years proven conrol of EAB.
• No other injection method has the proven results against EAB like Arborjet does.

What is the Threat

The Emerald Ash Borer (Agrilus planipennis) or EAB, is an invasive wood boring beetle that was first introduced from Asia to Detroit, Michigan in 2002 and is known to have spread to 36 states and four provinces. This small, metallic green wood-boring beetle attacks multiple ash species and can go unnoticed for several years. The larvae live under the bark of the tree and feed on the vascular cambium through the fall and winter. The feeding produces long serpentine galleries that can girdle branches and the main stem and lead to tree mortality.

Where is the Threat

EAB infests all ash species, but most commonly attack green, white and black ash. Initial infestations were documented in Michigan and Ontario, Canada. Populations continued to spread throughout the Midwest and Canada. In 2013, EAB eventually found its way to New England, Georgia and Colorado. By 2019, infestations have been confirmed from Texas and South Dakota to Nova Scotia, Canada.

Symptoms

EAB larvae live under the bark and create meandering galleries through the phloem, cambium and the xylem layers, effectively girdling the tree. In response to upper canopy dieback, trees will sprout new (epicormic) branches in the lower crown. Adults create D-shaped exit holes when they emerge in June. Bark cracks that reveal larval galleries and woodpecker activity are also signs of EAB infestation. Since EAB often goes unnoticed for several years, trees may die within two years of the onset of symptoms.
