Good Morning,
Excessive pine tree sap loss results from injuries like broken branches in a storm, pruning, or accidental cuts made by weed whackers. It can also result from borer insects that dig holes in the tree. Oozing of sap from the trunk of a pine tree can be an early sign of bark beetle damage. The sap accumulates near the bore hole in the bark and the sticky mess is called a "pitch tube." The pine produces excessive amounts of sap to protect itself against the bark beetle. Several types of beetles can attack pine. Perhaps you can identify one of these insects as one infesting your tree.

You can have an arborist come out and assess your tree.  Find certified arborists by searching under the “Find an arborist” tab, and using your zip code here—-www.treesaregood.org
