    Insecticides are effective in protecting trees from bark beetles. Insecticide solutions should be sprayed on the bark of the main bole, spraying sprayed as far up the trunk as possible and to a height of at least 30 feet. According to Oregon’s Department of Forestry (, the following insecticides can be used for preventing bark beetle attacks on standing pines:
    • Ground applications to forest trees: Carbaryl
    • Ground applications to ornamental trees: Carbaryl, Permethrin
