Monterey Bacillus Thuringiensis Insecticide Concentrate

Bacillus Thuringiensis (Bt) is a naturally occurring soil bacterium. When worms or caterpillars ingest the treated plant foliage, the bacteria produce proteins that specifically target their digestive systems, causing them to stop feeding within hours and eventually die.

Yes. This formula is highly selective, meaning it targets specific leaf-eating caterpillars and worms while remaining non-toxic to beneficial insects like honeybees, ladybugs, and earthworms when used as directed.

Absolutely. Because this is an organic-compliant biological insecticide, there is no pre-harvest interval required. You can apply it up to the day of harvest, though you should always wash your produce thoroughly before eating.

You can use standard garden equipment. A simple hand-pump spray bottle works well for smaller vegetable patches, while a tank sprayer is more efficient for larger garden beds or fruit trees.

No, this specific product is formulated to target caterpillars and worm-like larvae. It will not be effective against aphids, beetles, or other sucking insects.

For active infestations, reapply every 5 to 7 days as needed. Because the product works by ingestion, it is important to ensure thorough coverage on the leaves where pests are feeding.
