NATURAL GUARD CATERPILLAR KILLER SPRAY RTU 32oz

Stop leaf-chewing caterpillars instantly without mixing! This ready-to-use formulation delivers Bacillus thuringiensis (Bt), a naturally occurring, organic-approved soil bacterium. When caterpillars (worms) eat the treated leaves, the Bt paralyzes their gut, causing them to stop feeding immediately. It is specific to caterpillars and harmless to humans, pets, and beneficial insects like bees.

• Best For:
  • Edibles: Protecting vegetables and fruits from pests like Cabbage Worms, Tomato Hornworms, and Tent Catervae.
  • Small Gardens/Spot Treatment: Ideal for quick, targeted spraying of small infestations or single plants.
  • Organic Gardeners: A reliable, natural solution for worm control.
• Key Actionable Steps:
  • How to Apply: Shake well. Spray directly onto the foliage, ensuring thorough coverage of both the top and undersides of leaves, as the worms must ingest the product to die.
  • Timing: Apply when worms are small and actively feeding. Look for fresh chew marks.
  • Reapplication: Reapply every 5 to 7 days, especially after rain or watering, or as new foliage appears.
  • Pro Tip: Apply in the late afternoon or evening because sunlight rapidly breaks down the active Bt ingredient. Since this is a contact and ingestion product, full coverage is essential.
