Monterey B.t. Concentrate (Gal)
Biological Control of Many Worms and Caterpillars
Monterey B.T. Concentrate is a powerful, eco-friendly solution for controlling worms and caterpillars in your garden. Utilizing Bacillus thuringiensis (Bt), a naturally occurring bacteria, this biological pesticide targets the larval stage of pests without harming beneficial insects or the environment.
How It Works: Monterey B.T. Concentrate works by disrupting the digestive systems of worms and caterpillars when ingested. Once consumed, the bacteria release toxins that stop the pests from feeding, eventually causing their demise. This targeted action ensures effective control of a wide variety of caterpillars and worms.
Why Use Monterey B.T. Concentrate?
- Safe for Beneficial Insects: Does not harm birds, bees, or other helpful creatures.
- Effective Against a Wide Range of Pests: Targets pests like cabbage loopers, armyworms, and hornworms, especially in their vulnerable larval stages.
- Safe for Edible Plants: Use up to the day of harvest, ensuring your crops remain free from harmful residues.
Ideal for Vegetable Gardens & Ornamentals: Monterey B.T. Concentrate is perfect for protecting both vegetables and ornamental plants, including shade trees. It’s particularly effective against pests such as tent caterpillars, gypsy moths, and bagworms.
Optimal Application: For best results, apply when pests are in their early stages. Regular monitoring will help you catch infestations early, minimizing damage.
Eco-Friendly Pest Control: Monterey B.T. Concentrate is an environmentally safe choice, ensuring your plants remain healthy and your garden stays pest-free.
