Tree and Beetle Identification
The University of Wisconsin – Madison has a great deal of information on their Web site to assist in identifying ash trees and potential signs of infestation.

EAB Hotline – Ask Questions or Report Potential Beetle Sitings
DATCP has set up a hotline to request more information or to report possible sitings of EAB: 1-800-462-2803. 

Before calling the EAB hotline, please do the following:

1)   Make sure your tree has two or more of these symptoms

• D-shaped holes
• S-shaped scrolling under the tree bark
• Water sprouts (small leafy branches emerging from the base of the tree)
• Dieback in the canopy (leaves are yellowed and/or falling from the tree during the summer)
• Woodpecker activity
• Bullet-shaped, iridescent green beetles from May through August

2)  Make sure the tree in question in an ash.  If you're not sure, visit one of these tree identification web sites:

Department of Natural Resources

University of Wisconsin - Green Bay

3)  Be sure the green bug you saw is NOT an EAB look-alike.  If you're not sure, check this look-alikes page at the University of Wisconsin – Madison.

The hotline number is 1-800-462-2803 or send an email. 

If you can take a digital picture of any insects or exit holes, the images would be helpful in identifying the insect.  Email to the department.

If you capture any insects, place them in a sturdy container such as a pill bottle or small box and mail the insect to: Krista Hamilton, DATCP, 2811 Agriculture Dr., Madison WI  53718-6777.

If you have any questions or if you would like an information packet, please call the hotline or send an email with your name and address and we’ll send a packet in the mail.
