Over the past couple of years, I have noticed an infestation amongst several white pines as evidenced by bore holes, white sap and actually hearing the pests at work. I have already lost a couple of trees and hope that you can help identify the issue and a DIY solution that I may implement. I have attached a photo for reference. Any help would be greatly appreciated!
