Emerald Ash Borer

The Emerald Ash Borer (EAB) is an invasive species that has killed tens of millions of ash trees across the country. Its larvae tunnel under the bark and feeds on the part of the tree that moves nutrients up and down the trunk. 

The insect was first found in St. Louis County on Park Point in 2015, leading to a quarantine of just that area. In Sept. 2016, a new infestation was found on private property near Hartley Nature Center in Duluth. Following this, the Minnesota Department of Agriculture (MDA) imposed an emergency quarantine and began the process to establish a formal quarantine.


The Dept of Agriculture will hold an informational meeting:

Wednesday, Oct. 12, 6-8 p.m.

Rice Lake City Hall

4107 W. Beyer Road

Public comment on the formal quarantine can be given at the meeting, or by contacting:

Kimberly Thielen Cremers
Minnesota Department of Agriculture
625 Robert Street North
St. Paul, MN 55155

The deadline to submit comments is Nov. 30, 2016

Quarantine details 

The Minnesota Department of Agriculture has issued an emergency quarantine of ash wood and materials for the area running from U.S. Hwy 53/MN Hwy 33 on the west, and along Three Lakes Road (CSAH 49) on the north, to the borders with Lake and Carlton Counties on the east and south.

The emergency quarantine limits the movement of firewood and ash material out of the quarantined area of the county. This is to reduce the risk of further spreading the tree-killing insect.

A formal quarantine is expected to be adopted in mid-December.



What should you know and do?

The biggest risk of spreading EAB comes from people unknowingly moving firewood or other ash products harboring larvae. There are three easy steps you can take to prevent the spread:

  • Don’t transport firewood. Buy firewood locally from approved vendors, and burn it where you buy it;
  • Be aware of the quarantine restrictions. If you live in a quarantined county, be aware of the restrictions on movement of products such as ash trees, wood chips, and firewood; and,
  • Watch your ash trees for infestation. If you think your ash tree is infested, go to and use the “Does my tree have Emerald Ash Borer?” guide.
