Callen from Wilmington writes
I have pine beetles and I was told to spray Bifen IT on my dead tree that has the beetles and on the two surrounding the infected tree in order to make sure they didn't get the beetles as well.
Bifen IT will not kill trees only listed insects. If you have any severely damaged or dead trees, they should be removed to help prevent the beetles from infesting healthy trees in the surrounding area.
