Help Stop the EAB

The Emerald Ash Borer (EAB) beetle has killed tens of millions of trees, destroying our forests, fishing spots, campgrounds and neighborhoods. We need your help to protect our trees.

Never Move Firewood

The most effective way to stop the EAB is to not move firewood. The beetle’s eggs and larvae tunnel into the trees they infest. Cutting a tree into firewood does not kill EAB developing inside of it. Adult beetles can still emerge, infesting healthy trees when they do.

Burn It Where You Buy It

Humans can unknowingly transport the EAB hundreds of miles in firewood. That’s why it is so important to make sure your wood is from local sources and to burn it where you buy it. Don’t carry it across county or state lines. The best approach is to not move firewood from your property, and definitely don’t move wood out of quarantine areas. At many parks and campgrounds, firewood is sold on site. In fact, some state parks will not even allow people to supply their own firewood.

When purchasing any firewood, always ask about its origins. Ask if it is locally sourced. Before the onset of spring, be sure to burn your remaining supply of firewood to eliminate the chance of spreading any larvae living in it to live trees.

Report Beetle Sightings or Signs of Infestation

Ash trees are used extensively in residential and commercial landscapes and are found naturally in woodlots, along creekbeds, and in low-lying wetlands. Cooperation among Federal and State government agencies, municipalities, universities, the green industry and the public is essential to minimize the impact of this pest.  Here’s how you can help:

  • Read our fact sheet on identifying ash trees. Locate ash trees on or near your property.
  • Examine each tree for signs of infestations such as canopy dieback, epicormis shoots, S-shaped galleries, vertical bark slits and D-shaped exit holes.
  • If you observe beetles or evidence of EAB infestations, report your sighting to your State Plant Health Director.
  • If possible, take digital pictures of the insect and damage to your trees.

Stingless wasps

Stingless wasps are a natural enemy of the EAB. The U.S. Department of Agriculture is working with the Forest Service and Agricultural Research Service (ARS) to raise and harvest these stingless wasps for monitored releases in selected EAB infested locations. Specifically, they are using three parasitoid species of wasps from China called Spathius agrili, Tetrastichus planipennisi and Oobius agrili.

This year, wasps were released in 17 States: Connecticut, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Wisconsin. Additional parasitoid releases are expected in EAB-infested States when appropriate climate/release conditions are met.

The wasps target EAB eggs and larvae and use them as hosts to support their own species. The wasps’ offspring consume the EAB egg and larvae as they grow and develop.
