Saddleback Caterpillars on Crepe Myrtle: ID and Organic Control

Green caterpillars with a brown saddle-like spot circled in white, and spiky horns at both ends, are saddleback caterpillars. Their spines sting—wear gloves.

Control

• Hand-pick if numbers are low (gloves!).
• For larger infestations: apply Bacillus thuringiensis (Bt) products like Dipel or Thuricide—biological, caterpillar-specific.
• Sevin (carbaryl) is a broader option but harms beneficials.
• Confirm ID via Google Images before buying any product.

Crepe myrtles tolerate some defoliation; treat only if heavy.
