Emerald Ash Borer (EAB)

What is EAB?


Emerald ash borer (EAB) is a devastating wood-boring tree pest that has killed millions of trees across Minnesota including all of southeast Minnesota.  We know, we see cases weekly.  While EAB is all but impossible to eradicate once it arrives in an area, well-planned response efforts can slow its spread and reduce the impact on community forests.


Preventative maintenance is crucial.



AAA owner Andre Schimdt is certified by the Minnesota Agriculture Department to do tree injections.  Andre will inject your trees with a tree friendly chemical to help prevent EAB from getting into your tree.  The chemical gets into the trees truck then it gets “sucked” up into the entire tree, making it protected from top to bottom.  Trees help your home with curb appeal and shade.  Protect them and help stop the spread of the Emerald Ash Borer.

Does EAB attack Mountain Ash?

EAB attacks all ash species found in Minnesota: green (F. pennsylvanica), black (F. nigra), and white ash (F. americana).

Mountain ash (Sorbus. spp.) is NOT a true ash and is NOT attacked.University of MN Extension

Do EAB adults die over winter in Minnesota?

In southern Minnesota adults can survive the winter as evidenced by the populations present in the Twin Cities and Houston County.  However, winter conditions in northern Minnesota may prove more difficult for EAB and research is ongoing to address that question. – Minnesota DNR

Are there any other flat-headed borers that attack ash trees?

In addition to EAB, other flat-headed borers that might be found in ash include Chrysobothris spp. and Dicerca spp. Both of these borers can be easily distinguished from EAB by both the appearance of the larvae and the shape of the tunnels they leave behind. –University of MN Extension
How far can EAB adults fly?
Laboratory studies have shown that EAB adults are physically capable of flying several miles. However, it appears that most individuals do not fly very far (< 1/2 mile) before infesting a new tree.  – Minnesota DNR

What is the expected life span for black, green, and white ash trees?

As boulevard trees? The life span for urban boulevard trees may range from 10 years to 80 years for the ash genus.  Even though ash trees are known for their urban resilience, many variables ranging from road construction to salt damage dictate the life span of these trees. – University of MN

Why is it more expensive to remove a dead ash than a live one?

Removal of dead trees can more expensive because of the risk associated with removing dead trees.  Live trees can be pieced down by an arborist whereas dead trees require more equipment since it’s not necessarily safe for an arborist to climb the tree. – University of MN
