Grow Organic Monterey B.t.

This product is specifically formulated to target caterpillars and worm-like larvae, such as tomato hornworms, cabbage loopers, and bagworms. It is not designed to control aphids, beetles, or other non-caterpillar garden pests.

Yes. Because it uses a natural bacterium rather than synthetic chemicals, it is safe for use on edible plants. You can apply it to your vegetables right up until the day of harvest.

No, Monterey B.t. is selective. It is safe for beneficial insects like bees and ladybugs, as well as birds and earthworms, because it only affects specific caterpillars that ingest the treated foliage.

While the pests may not die immediately, they will stop feeding on your plants almost instantly after ingesting the treated leaves. They typically perish within a few days.

No, this is a ready-to-use formula. It comes in a spray bottle, so you can apply it directly to the foliage of your plants without any additional preparation.

For the best results, apply the spray when the pests are young and actively feeding. Since the product must be ingested to work, ensure you thoroughly coat the leaves where the caterpillars are present.
