Pine tree needs help!

Asked September 8, 2015, 12:32 AM EDT

Insects of some kind are attacking our pine tree from the base of the tree. There is a pile of "sawdust." We saw a few black ants on the tree but not at/in the visible holes. Picture 5 shows the needles. There are also three more of the same type tree that we haven't noticed holes in yet. What can we do or who do we call?

When trees are subject to drought, soil compaction, too much moisture, poor drainage, planting too deeply, etc. they are susceptible to insect and disease problems. If you are seeing sawdust sounds like the pine tree was subject to some type of boring insect, we cannot say which one. At this point, the borer is a secondary issue. Borers affect the vascular system of the tree and it is usually just a matter of time before they decline. Dead or dying trees should be removed. For an onsite diagnosis regarding the health of the tree, contact several certified arborists for the best way to proceed .http://www.treesaregood.org/
