Pine Beetle Defense After Drought

Pines produce resin (sap) continuously, but drought reduces resin flow, weakening defense against bark beetles. Once beetles infest a stressed tree, recovery is unlikely. There's no fixed timeline for resin recovery—it depends on rainfall, tree vigor, and species.

Management Options

Prevention: Deep watering during drought, mulching, avoiding injury.
Monitoring: Watch for pitch tubes, boring dust, fading crown.
Treatment: Certified arborists may inject systemic insecticides for high-value trees.
Sanitation: Remove and destroy infested trees promptly.
