IPS Bark Pine Beetles (Engraver Beetle) Control & Management

These beetles are classified as borers. Both adults and larvae tunnel into (or engrave) the vascular tissue (phloem) that carries nutrients just under the bark. All stressed trees are vulnerable to attack and should be examined for signs of beetle activity. Here’s how to control and manage IPS engraver beetle infestations.
Several species of IPS bark beetles (also called engraver beetles) primarily attack both pine and spruce trees. Adults are about the size of a dull pencil point and vary in color from brown to black.
