Will Ferti-lome Tree and Shrub Systemic Insect Drench kill the beetle that attacks the lodgepole pine trees?


  Due to the natural boring behavior of the beetle, they are protected from topically applied insecticides and systemic insecticides (such as Ferti-lome Tree and Shrub Systemic Insect Drench) have proven ineffective for pine beetle infestations. 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.  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.
