The prior owner of my property brought home firewood infested with pine borers. Now all my pines are dying. How can I save them?
Unfortunately, there is no easy solution when it comes to pine beetles and Bayer Advanced 12 Month Tree and Shrub Protect and Feed II would not be recommended for them. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations. Healthy trees can be protected before the beetles attack by topically spraying them with a product called Permethrin SFR. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations.
