Oc-casionally black and grey squirrels will feed on the larvae and leave ragged strips of bark on the stem C. These large ash trees grow between 60 to 80 ft. The cumulative damage from larva feeding on the inner bark eventually kills ash trees within two to four years.

EAB is a significant threat to all ash species. Emerald ash borers damage your trees by laying dozens of tiny 12 mm eggs on the bark. The invasive insect from Asia is a significant threat to all ash species.

Look closely where the bark. Pumpkin ash trees are tall deciduous trees native to the eastern United States. Adults then chew their way out of the tree leaving exit holes.

The first sign of EAB attack is vertical cracks in the bark usually accompanied by woodpecker damage. Look closely where the bark. The beetle lays eggs between bark crevices and when the larvae hatch they bore into the tree.

Entire trees may be killed by bark beetles. Ash borers usually attack a tree first in the upper parts of the canopy so damage is usually far advanced by the time emergence holes or damage are seen on the lower trunk of the tree. Woodpecker activity and damage on live trees is often an initial symptom of an EAB infestation.

Pumpkin ash bark is gray thick and fissured. Ash bark beetles may infest almost the entire tree. It is the cumulative damage by larval feeding on the inner bark that eventually kills ash trees.

Ash trees can have 33 50 damage in the upper branches but still survive if treated. Initial damage appears as thinning in the upper canopy of the tree and branches can die over time. Aculeatus and the western ash bark beetle H.
