Review: Safe and Highly Effective Natural Pest Control Solution - Bonide Thuricide BT Concentrate has become my go-to solution for managing caterpillar and worm problems in my garden. As someone who prioritizes organic and environmentally responsible gardening practices, I was thrilled to discover this product that effectively controls pests without using harsh chemicals that could harm beneficial insects, pets, or my family. After using it throughout multiple growing seasons, I can confidently say this is one of the best pest control products I've ever used. The active ingredient in this product is Bacillus thuringiensis, a naturally occurring bacteria that specifically targets caterpillars, worms, and moth larvae while being completely safe for humans, pets, birds, and beneficial insects like bees and ladybugs. This selective targeting is exactly what I was looking for, as I want to protect my plants without disrupting the entire garden ecosystem. The peace of mind that comes from knowing I'm not spraying toxic chemicals near my vegetables, herbs, and areas where my family and pets spend time is absolutely invaluable. The concentrate formula is incredibly economical and provides excellent value. A little goes a long way when mixed according to the instructions, and the 16-ounce bottle has lasted me through multiple applications across my entire garden. The ready-to-mix formulation makes preparation simple and straightforward. I simply measure out the appropriate amount, add it to water in my garden sprayer, shake well, and it's ready to apply. The mixing process is easy and the product dissolves completely without leaving any residue or requiring complicated preparation steps. Application is straightforward and effective. I spray the mixture thoroughly on the foliage of affected plants, making sure to coat both the top and undersides of leaves where caterpillars typically feed. The product works by being ingested by the target pests as they eat the treated foliage. Within hours of application, the caterpillars stop feeding, and within a few days, the problem is completely resolved. I've used this successfully on tomatoes, cabbage, broccoli, ornamental plants, and fruit trees with consistently excellent results. The effectiveness of this product is truly impressive. I've dealt with various caterpillar problems including cabbage worms, tomato hornworms, and tent caterpillars, and Thuricide has successfully controlled every infestation I've treated. What I especially appreciate is that it works quickly enough to prevent significant damage to my plants, yet it does so through biological means rather than chemical toxicity. This makes it perfect for organic gardening and for use on vegetables that will be harvested and eaten. One of the best features is its safety profile.
Review: Great for tomato horn worms - Works great on the pesky Tomato worms and squash bugs. Just spray late or early enough that you don't harm friendly pollinators. Came with measuring cup as well. Will buy again.

### ⭐⭐⭐⭐⭐ Amazing 3-year supply
*by E***E on October 11, 2023*

I bought a 16 ounce bottle of this Thuricide BT, kept it in the fridge, and used it for three years to keep the green worms off of my broccoli and kale. Each year, I had to mix it a little bit stronger. Now, at the end of the 3rd year, it’s still working, but I plan to buy a new bottle next spring. This stuff is amazing. For years, I tried to do organic gardening with diatomaceous earth. BT works 1000 times better. I even had pretty good success spraying my apple tree with it. If I spray the apples well every week or two and after each heavy rain, they didn’t get worms. I injected it with a syringe into the stalks of my zucchini and was able to beat the zucchini stock borers.
