Do you agree that it is very effective for tomato fruit pests?** A: Yes it is. It's hard to find in stores anymore so Amazon is best source. It works and maintains organic qualities. **Q: Just curious as to why the info says "Approved for organic gardening" as opposed to simply "organic"!

You should start using it before you see damage and then regularly every two weeks to keep them from taking over your plants. Worked great on my supertunias last summer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff is awesome! *by A***Y on August 10, 2026* Huge value! I had a confirmed squash borer infestation that hadn't quite killed off my 3 types of squash plants. Using a syringe, I was able to quickly inject and treat all my squash plants. Weeks later, they are thriving! I now treat stems, leaves, and dirt with this stuff and have not had a recurrence! ### ⭐⭐⭐⭐⭐ Worked in 1 Application *by A***S on August 19, 2026* Worked to eliminate my bug issue on zucchini plants after 1 application. Recommend! ### ⭐⭐⭐⭐⭐ CATERPILLARS BE GONE! 🪄💥🐛 *by L***S on July 9, 2026* This stuff works. A few weeks ago, within a 48 hour period, caterpillars completely decimated my petunias. After spending too much time combing through my flowers trying to find them, I googled “what kills caterpillars that are eating my petunias” and I was lead to this wonderful product. It kills caterpillars specifically and does not harm bees or butterflies or other pollinators. Make sure to spray in the evening as the sun could burn the plants in the heat of the day. THIS STUFF STINKS. Like a very musty smell that’s honestly horrendous, but a very small price to pay for how effective it is. I doused my flowers once, gave it about 5 days and sprayed them again. That’s it. First picture is June 23rd and last picture is July 8th. I will continue to recommend this product to anyone having issues with those godforsaken caterpillars destroying your garden! ## Frequently Bought Together - Bonide 8066 Captain Jack's Bacillus Thuringiensis BT Organic Worm & Caterpillar Control, 32 oz.
