If my neighbors trees are all dead and dying from beetle kill, is it worth spraying my pine trees to try and save them? Currently they show signs of stress but not kill.

Thank you for your question. See links below - information on Ips and Pine Beetles. Lots of details on how to manage your trees and what to do to prevent an infestation. You want to identify the type of beetles in the area; prevention techniques are not the same.
