Distinguished easily by dying tips - a late sign of infestation, indicates the tree has lost the battle to Bark Beetle and should be safely removed. A healthy tree will generate an abundance of sap in order to defend against this harboring pest; though far to often it is too late. The adult beetle carries a fungus which blocks the inner bark from the sapwood causing the tree to die out. In wake of the drought, trees have been severely weakened and left even more vulnerable to an attack. Woodpeckers aid in damage by removing outer bark to feed on larvae. Once one tree has reached it's demise, surrounding trees quickly fall victim.
This is when eradication comes in, to further promote protection to healthy, neighboring trees. It is recommended to first professionally diagnose that the trees are indeed plagues with Bark Beetle. Once diagnosed, a plan of action can be put into place. We highly encourage that the infested trees be removed and fully disposed of as promptly as possible. The longer the dying trees stand, the more dangerous they become to remove -- not only does this promote further spread, but impacts cost efficiency. Due to the inherent danger of removing a decaying tree verses a more sturdy tree, risk is significantly increased and options of removal methods become increasingly limited.
Signs of an infestation:
- Small entry holes (1/4" - 1/2") around the trunk of the tree made up of sap and dust
- Dying tips; discoloration of foliage -- either a lone tree or most often in clusters
- Woodpeckers which remove the outer bark and feed on the larvae
- Egg galleries and larvae beneath the bark or on the sapwood
- Debris at the base of the Pine made by beetles
