Monterey B.t.

Monterey B.t. is an effective natural caterpillar and worm-stage pest control that is safe to animals, people, and beneficial insects like honeybees and ladybugs. The active ingredient is baccilus thuringiensis, a bacteria found naturally in soils. This bacteria paralyzes the target pest’s digestive system, causing them to stop feeding within a few hours of eating the product, where they will die within hours. Monterey B.t. can be used on fruits and vegetables, ornamentals, and shade trees. It can be applied up to one day before harvesting.

Active Ingredient: Bacillus thuringiensis - 98.35%
Target pests: Caterpillar-type insects, Cabbage Looper, Imported Cabbage Worm, Tomato Hornworm, Bagworm, Spring Cankerworm, Fall Cankerworm, Gypsy Moth, Tent Caterpillar, Elm Spanworm, Fall Webworm
For use in: Fruits, Vegetables,Ornamentals and Shade Trees
Application: Fruits and Vegetables: 1.5 oz. per 3 gallons of water per 1,000 sq. ft.
Ornamentals: 2 oz. per 3 gallons of water per 1,000 sq. ft.
* See label for complete application instructions
Pet safe: Yes, when used as directed on the product label

    5 of 5 Stars  10 STARS IS MORE LIKE IT:)

    I bought this stuff and have used it religiously on my cole crops and tomatoes for loopers, horn worms, and cut worms twice a week. Last year I sprayed pesticides just to kind of keep up with them and still didn't end up with any brussel sprouts. This year my plants are prettier than the garden books:) And best of all I have good bugs this year; real butterflies, all kinds of good bees and therefore all kinds of produce:) I just cant rave enough. I wish I would of known a few years ago. I'm trying to stay organic and this makes it easy. Thanks!

    Did not kill bagworm one. A total waste of over twenty dollars. Applied it several times to my trees, and the infestation was completely unchecked. This review is being blocked by the site too I strongly suspect. I keep submitting the review, and it will not go through. Asking for 75 to 300 words. Totally unnecessary.
