Monterey B.t. for Organic Gardening

This formula is specifically designed to target caterpillar-type insects. It is not a broad-spectrum insecticide and will not be effective against beetles, aphids, or other non-caterpillar pests.

Yes, it is OMRI listed for organic gardening. Because it has a 0-day pre-harvest interval, you can safely apply it to your edible crops right up until the day you plan to harvest them.

No. The biological formula is selective, meaning it targets only the caterpillars that ingest it. It is safe for beneficial insects like bees, ladybugs, and birds.

The bottle comes with a built-in sprayer head that attaches directly to your standard garden hose. Once connected, the water pressure automatically mixes the concentrate at the correct ratio as you spray, eliminating the need for manual measuring or mixing.

Once the caterpillars ingest the treated plant material, they stop feeding almost immediately. While they may take a few days to die, the damage to your plants will halt as soon as they consume the product.
