A serious pest to all kinds of ash trees, the ash bark beetle lays its eggs in twigs and branches. Larvae develop and start tunnelling at right angles to the tunnel made by the adult female. As feeding continues and insects grow in size, gradually, the flow of sap in the twig or branch is cut off and the leaves towards the end of the limb begin to yellow, wilt and eventually die.
Heavily infested trees accumulate large quantities of deadwood in the crown as succeeding generations re-infest the same host until the tree dies. Lack of sufficient water, poor soil and improper pruning will make ash trees susceptible to bark beetles.
We recommend a full range of control measures from pruning to fertilizing to combat this problem. If the presence of ash bark beetles can be diagnosed early, most trees will completely recover within a few years. Contact us today.
