Monterey Bacillus Thuringiensis

Yes, it is organic-compliant and safe for use on vegetables, fruits, and ornamental plants. Because it targets specific leaf-eating caterpillars, it won't harm the plant itself or beneficial insects like bees and ladybugs.

Yes, this is a concentrated formula and must be diluted with water according to the instructions on the label. It is not a 'ready-to-use' spray, so you will need a garden sprayer to apply it.

Monterey B.t. works through ingestion. Once the target caterpillars or worms eat foliage treated with the product, the naturally occurring bacteria disrupt their digestive system, causing them to stop feeding and eventually die.

No, it is highly specific. It only targets leaf-eating caterpillars and worms, such as tomato hornworms, cabbage loopers, and bagworms. It will not be effective against aphids, beetles, mites, or other non-caterpillar pests.

B.t. breaks down relatively quickly in sunlight. For the best results, reapply every 7 to 10 days, or after significant rainfall, to ensure the foliage remains protected while the pests are active.
