Monterey Bt is a biological insecticide specifically designed to target caterpillar larvae, including common garden pests like bagworms, cabbage loopers, and tomato hornworms. It does not affect other types of insects.

Yes, it is safe for use on vegetables, fruit trees, and ornamentals. Because it is OMRI listed for organic gardening, you can apply it to edible plants right up to the day of harvest.

No. When used according to the label directions, this product is safe for beneficial insects like honeybees and ladybugs, as it only impacts the digestive systems of specific caterpillar larvae.

Yes, this is a concentrate, not a ready-to-use spray. You will need to mix it with water and apply it using a hand sprayer or a hose-end sprayer.

The product works by disrupting the pest's digestive system. Caterpillars will stop feeding within minutes of ingestion and typically perish within a few days.

It is considered safe for pets once the application has dried. However, it is not labeled as child-safe, so you should keep children away from the area during application and until the spray has completely dried.
