Pine Sawyer Beetles: Secondary Invaders in Dying Pines

Munching sounds + sawdust in GA pine = pine sawyers. They infest dead/dying pines only, not healthy trees. Larvae feed under bark, leave coarse frass. They don't spread to live trees; compete with bark beetles. No treatment needed—they're a symptom, not cause. Onyx (bark beetle insecticide) kills them if desired.
