But in recent years, the state has been battling a growing threat: the South American Palm Weevil (SAPW). This highly destructive pest is capable of killing a mature palm in just a few months.

This comprehensive guide will help you recognize weevil damage early, explore professional treatment options, compare pricing, and learn how expert palm weevil pest control CA services protect your landscape.

Signs & Symptoms of South American Palm Weevil Infestation

Early detection is the only way to save an infested palm. The weevil attacks the crown first, burrowing deep into the tissue where damage goes unnoticed until it becomes severe. By the time external symptoms appear, the infestation may already be advanced.

Common Warning Signs of SAPW Infestation

• Yellowing, wilting, or drooping fronds
• Frass (sawdust-like material) and small round holes near the crown
• A foul, fermented odor indicating internal decay
• Missing spear leaf, one of the earliest red flags
• Internal tunneling that weakens structural integrity
• Soft, hollow, or unstable trunk when tapped
• Crown collapse, a sign of irreversible damage
  

Because these symptoms can mimic other palm issues, a professional arborist tree inspection is essential for accurate diagnosis.
