What do I spray to kill pine beetles?

I have about 10 acres of long leaf pine trees that are in rows. We harvest the pine straw to sell but the trees are dying in sections and I found out it was pine beetles. What do I spray and do I use the boom or spray the sections that are infested with a wand I guess each tree that has it or what thanks nelson


Unfortunately, there is no easy solution when it comes to pine beetles. 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.
