  • OMRI‑listed biological insecticide made with Bacillus thuringiensis kurstaki (Btk).
  • Targets and controls caterpillars and worm‑type insects on fruits, vegetables, ornamentals, and shade trees.
  • Ready‑to‑spray formula requires no mixing—attach to hose and apply.
  • Can be used up to and including the day of harvest for organic gardening.

Monterey Bt Ready‑to‑Spray Insecticide provides effective, naturally derived pest control for home gardeners seeking organic solutions. Powered by Btk, this biological insecticide specifically targets caterpillar and worm larvae, stopping feeding shortly after ingestion and protecting crops without harming beneficial insects. Its convenient hose‑end spray design makes large‑area applications easy, delivering fast, reliable pest suppression for fruits, vegetables, ornamentals, and landscape plants—all the way through harvest time.


Target Pests

Effective against caterpillars, cabbage loopers, bagworms, gypsy moth larvae, leafrollers, armyworms, cutworms, hornworms, elm spanworms, cankerworms, and other worm‑type pests.

Active Ingredient

Contains Bacillus thuringiensis kurstaki (Btk), a naturally occurring bacteria that disrupts the digestive system of susceptible larvae.

Where to Use

Safe for application on fruits, vegetables, nuts, berries, flowers, ornamentals, shade trees, and in home garden landscapes.

How It Works

Pests must ingest treated foliage for the product to take effect. Feeding stops immediately, and larvae die within several days.

Application Instructions

Harvest Safety

May be used on edible crops up to and on the day of harvest.
