Hi Roger,

What makes you think it is infested with borer? Have you seen any exit holes where they have left the tree in their maturity? (usually round or oval shaped holes in the trunk) If the only evidence of borer infestation is the crown thinning mentioned above, I suggest you get an Arborist out to give you an aerial assessment. Die-back can simply mean so many things.

In the case that your trees do have borer, you have caught it an they early stages of the trees decline. If you had crown thinning of 50% or more there is a largely reduced chance of bringing them back.

Go here for a list of insecticides you can use to treat an infestation (advisable after confirmation of infestation and to be applied by a professional arborist.

Hopefully there is no need for tree removal.

Best of luck
