Bonide® Borer-Miner Killer

Specifically formulated to prevent the tree damage caused by borers. Larvae of these bad bugs tunnel under bark on tree trunks or lower limbs. A visual clue that this may be a problem with your tree is a gummy residue on trees of stone-type fruits where borers are feeding. The trees can then lose vigor and may even eventually die.

Permethrin, the key ingredient of this insecticide, is by far the most effective killer of tree borers. Apply three times throughout spring and early summer. We recommend the last two applications about July 1st and July 15th.

  • 8 Ounce Concentrate: Makes 4 gallons of solution for fruit & nut trees.
  • 16 Ounce Concentrate: Makes 8 gallons of solution for fruit & nut trees.
