[QUOTE="Gate Keeper, post: 697159, member: 15443"] I'm not so sure they are harmless. The beetles (Pitch Mass Borers) actually bore test holes in to the cambium to see how much sap is flowing. That is why if you look at certain pine trees there will be multiple masses of pitch. They do this to find a weak tree. Once the weak tree is found they produce a pheromone and more beetles arrive. I have used Bidrin Injection to stop these pests, along with other pests like pine bark beetle and ambrosia beetle. [/QUOTE]
