Natural Guard Caterpillar Killer Spray with Bt (8 fl. oz.) is a highly effective, organic‑friendly biological insecticide designed to control a wide variety of destructive caterpillar and worm species. Powered by *Bacillus thuringiensis*, this targeted formula works when pests consume treated foliage—causing them to stop feeding almost immediately and die shortly thereafter. Safe for use on fruits, vegetables, ornamentals, and shade trees, this non‑toxic solution protects plants without harming pollinators, earthworms, or other beneficial organisms. Its versatility and day‑of‑harvest safety make it an excellent choice for home gardeners seeking reliable, natural pest control.


How It Works

Bt is a naturally occurring bacterium that produces proteins toxic to caterpillar‑stage insects. Once ingested, pests stop feeding and die, minimizing plant damage.

Target Pests

Controls tomato hornworms, cabbage loopers, imported cabbage worms, bagworms, tent caterpillars, gypsy moth larvae, fall webworms, and other leaf‑chewing worms.

Where to Use

Safe for application on vegetables, fruit crops, ornamentals, lawns, shade trees, shrubs, and flowering plants.

Active Ingredient

Contains Bacillus thuringiensis (Bt) at 15% concentration, providing potent biological control in a sprayable formulation.

Safety & Environmental Benefits

Non‑toxic to people, pets, birds, earthworms, honeybees, ladybugs, and other beneficial insects when used as directed. Acceptable for use on edible plants up to the day of harvest.

Application Instructions

Spray foliage thoroughly at the first sign of infestation. Reapply weekly or as needed. Shake well before use for best results.

Organic Gardening

OMRI‑listed and approved for organic production, making it an ideal addition to sustainable garden care routines.

Performance Notes

Visible plant protection begins immediately as feeding stops; full pest mortality follows within days depending on pest type and size.
