Emerald Ash Borer (EAB) has been lurking in the news background for the last several years. Now they are in your neck of the woods. Here are the top 5 things you need to know about EAB.

Who needs to know about emerald ash borer

EAB feed on the nutrient dense part of the tree right below the bark. This beetle is host specific and feeds on Ash Trees including:

  • Black Ash (higher preference)
  • Blue Ash
  • Green Ash (higher preference)
  • White Ash

While the adult Emerald Ash Borer prefers to lay eggs in open stand or stressed trees, they may lay them on any tree. More susceptible trees are located in an area with:

  • compacted soil
  • soil affected by road salts
  • more heat pressure from lack of shade from other trees
  • it may be more susceptible.

What kinds of damage do EAB’s do?

Emerald Ash borer feed beneath the bark on nutrient dense tree tissue. They leave S-shaped grooves underneath the bark. This feeding pattern blocks normal flow of food and water throughout the tree’s system.

Once EAB settle into an area, they can kill Ash trees within 10 years. With that short amount of time, putting control measures in place to protect the ash trees is vital.

How should you treat for Emerald Ash Borer

The first step in defense against EAB is keeping the Ash tree well groomed and healthy. Having a natural mix of vegetation and trees around Ash trees improve its overall health.

The second step is to monitor the trees. Quarantine and remove affected trees.

Most importantly, there are preventive measures available. Professional applicators can inject a systemic product into the tree to provide ongoing protection. Additionally, 3 species of parasitic, non-stinging wasps are great for combatting the invasive beetles:

Where are Emerald Ash Borer right now?

Early detection of EAB was in Michigan and the beetle has spread across Wisconsin, Minnesota, and many other states. Arborists, Departments of Agriculture, and many other agencies are joining together to get the word out and encourage a strong defense.

Why are EAB a spreading threat?

As an invasive species, the Emerald Ash Borer made its way to the US without its natural predators. Additionally, many local cultural practices left trees susceptible to infestation. These beetles spread quickly and work their tragic powers rapidly as well. The beetles are able to fly from tree host to tree host and affected firewood spreads the threat.
