Stein Tree Urges Emerald Ash Borer Inspections for National Invasive Species Awareness Week

Feb 26, 2018 – Wilmington, DE – Local tree care company Stein Tree Service reminds Wilmington residents that this week is National Invasive Species Week (NISAW). The week, set apart by the nonprofit of the same name, encourages awareness of invasive plants and insects, such as the emerald ash borer (EAB) and the spotted lanternfly, that can negatively impact our plant life.

The emerald ash borer, which was just discovered in Delaware for the first time last year has moved rapidly through areas across the United States since its first sighting in 2002. The emerald ash borer primarily attacks ash trees, which flourish in the Delaware and Pennsylvania climates, but has recently been found to be attracted to fringe trees as well.

Events such as the NISAW help increase awareness of these dangerously destructive creatures, which is critical to saving affected trees and preventing the spread. The emerald ash borer can cause such damage to an ash tree as to completely destroy it within two years. The beetle consumes the nutrients of the tree, beginning with the inner wood under the bark as larvae, and then as adults, from the tree’s canopy.

If the emerald ash borer is discovered early enough, a professional tree care company may be able to save the affected trees. The key is to be vigilant, looking for any signs of the insect or of loss of vigor in your trees.
Signs of the emerald ash borer include:

  • D-shaped holes in bark – Created as larvae emerge from under the bark
  • Excessive woodpecker activity – Woodpeckers feed on the EAB larvae. The birds strip the bark off to get to their prey.
  • Galleries under the bark – formed as the emerald ash borer larvae moves and eats under the bark surface.
  • Epicormic Sprouting – This symptom is an indication of some sort of sickness or infestation. Even if the culprit is something other than EAB, you should have a professional inspect the tree.
  • Crown Thinning- The emerald ash borer feeds on the canopy, but in addition, over an extended infestation, the nutrients and water supply to the top of the tree will be disrupted.

The NISAW encourages awareness of all types of invasive species, but the emerald ash borer is a definite local threat that homeowners should be aware of. Spring is a good time to schedule an inspection of the trees in your landscape to ensure that they are healthy and free of problematic issues.
