Grow Organic Safer Caterpillar Killer II

Safer Caterpillar Killer II uses Bacillus thuringiensis (B.t.), a bacterium that only affects the digestive systems of specific leaf-eating caterpillars and worms. Because it must be ingested to work, beneficial insects like bees and ladybugs are not harmed as long as they do not consume the treated foliage.

Yes, this product is safe to use up until the day of harvest. Simply wash your fruits and vegetables thoroughly before eating them, as you would with any garden-grown produce.

The active ingredient, B.t., is sensitive to ultraviolet light and can break down quickly when exposed to direct, intense sunlight. Applying it in the late afternoon or on overcast days ensures the product remains effective on the leaf surface long enough for the pests to ingest it.

It is effective against a wide range of caterpillars and worm-like larvae, including cabbage loopers, tent caterpillars, and gypsy moth larvae. It is designed specifically for these leaf-chewing pests and will not control aphids, beetles, or mites.

Yes, the OMRI (Organic Materials Review Institute) listing confirms that this product meets the strict standards required for use in organic gardening. It utilizes a naturally occurring bacterium rather than synthetic chemicals.
