Monterey B.t. Worm-Caterpillar Control is a biological insecticide that uses the beneficial bacteria Bacillus thuringiensis subspecies kurstaki strain SA-12 (Btk) as its active ingredient. This biopesticide works by introducing bacterial spores and toxins into the body of the insect larvae as it feeds on foliage. These toxins quickly disrupt, and soon completely stop, normal digestive functions of the pest insect. The infected larvae will cease eating and fully succumb to the effects of the Btk within 2-5 days.

Working as a foliage protector this insecticide is safe to use in your organic garden and is designed for use on a variety of edible plants including broccoli, celery, cabbage, turnip greens, mustard greens, cauliflower, melons, lettuce, tomatoes, shade trees, ornamentals, and many more.
