Bagworms & Webworms in Pecans: Texas Timing

Central Texas pecan owners: bagworms (early summer) and fall webworms (early fall) need Texas-specific timing.

Bagworms

• Hatch: Late April–May.
• Treat: Early June (small bags) with Bt, spinosad, or permethrin.
• Hand-pick fall–spring.

Fall Webworms

• Generations: 2–4/year in Texas.
• Treat: First generation (May–June) to prevent buildup.
• Bt, spinosad, or carbaryl on webs.

Prevention

• No trunk barrier stops them—they balloon in on silk.
• Monitor weekly May–Oct.
• Spray only when seen; cover canopy thoroughly.
