Where did the EAB come from and how did it get here?

The EAB is native to Asia and Eastern Russia. It is believed that the EAB unintentionally arrived in the United States in the 1990s by means of wood packing material used to stabilize shipping crates.

When will the EAB arrive in Council Bluffs?

The EAB will arrive in Council Bluffs within two to four years. Without intervention, the EAB will potentially destroy thousands of ash trees in the city.

What happens to infested ash trees?

EAB larvae cause massive damage as they feed on the conductive tissue of the tree and block nutrients and water from traveling between the tree’s roots and leaves. At the onset of winter, the larvae relocate to the bark of the tree, causing even more damage and ultimately causing the tree’s death.

How do I know if my tree has been infested by EAB?

Signs of EAB infestation include:

  • Dieback (thinning) of the upper and outer crown of the tree
  • New growth on the tree’s trunk
  • Split bark or bark chipped off by a woodpecker
  • D-shaped holes on the bark
  • S-shaped tunnels beneath the bark

What do EABs look like?

The adult EAB beetle is a dark, metallic green color and measures approximately 1/2-inch long and 1/8-inch wide (about the size of a penny).

How does the EAB move from place to place?

The EAB can fly, but its range is limited to approximately 3-5 miles per year. The widest spread infestation in the United States is accomplished through man-made means, particularly through the movement of firewood.
