What is the Emerald Ash Borer?

Emerald Ash Borer (EAB), Agrilus planipennis, is an Asian beetle first discovered in Michigan in 2002. It has since spread to other nearby states. This invasive species poses a serious threat to the ash trees in southeast Michigan and Oakland County, including West Bloomfield Township. Adult beetles are approximately 3/4" long and are a green metallic color, and the larvae are only about 1 mm long and a creamy white color. The hatching season lasts through spring and summer. To view pictures and learn more details about this beetle, please view the Michigan Department of Agriculture brochure on the Emerald Ash Borer.

 

What damage does a EAB cause?

The adult beetles do eat the foliage of trees, but the larvae have a bigger impact. The larvae feed on the inner layers of bark, stopping water and nutrients from freely flowing in the tree. This "blockage" will kill the ash trees. A dead ash tree is a good sign that Emerald Ash Borers are present in the area.

 

What should you do to protect the environment?

Transported firewood is the easiest way for the EAB to spread from location to location.

  • Please use only local firewood for burning.
  • Do not remove firewood from Oakland county. This wood is quarantined and removing it is illegal.
  • If you have moved firewood, burn it immediately.

If you discover an EAB infestation on your property, please call the MSU extension number below, or contact the Michigan Department of Agriculture EAB hotline at
