Bonide Captain Jack's Bacillus Thuringiensis BT, 32 oz | Ready-to-Use Spray, Worm & Caterpillar Control, For Organic Gardening

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 to eliminate my bug issue on zucchini plants after 1 application. Recommend!

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!

Bonide Captain Jack’s Thuricide has worked well for keeping caterpillars from chewing up my garden plants. I like that it targets leaf-eating worms and caterpillars without feeling like I’m using a harsh general-purpose insect killer. It was easy to apply, and after a couple applications I noticed less new damage on my vegetables. The main downside is that it is not an instant knockdown product. You have to apply it thoroughly, especially underneath leaves, and reapply after rain or heavy watering. It also seems to work best when the caterpillars are still small, so you need to stay ahead of the problem. Overall, it’s a solid garden product and I’d buy it again. Four stars because it works, but it takes consistent application and a little patience.

An aphid infestation appeared overnight on my magnificent newly purchased hibiscus. I was devastated thought I was going to lose it check to see what product I could try to save it and purchased this product. I am happy to say it is perfect again blooming beautifully and this product saved my plant. I recommend it highly.

I’m really happy with this product! I like that it helps control caterpillars on my petunias flowers.Overall, a great addition to my gardening supplies, and I would definitely recommend it to anyone looking for an easy solution to protect their plants!🪴 here is the before and after pictures.

I haven't had time to find out if this works on my plants yet but it looks like it is making the broccoli and Brussel sprouts are getting greener and the worm damage has stopped.

It would have been nicer if the sprayer was with the product that arrived this morning. The 3 stars are for the missing sprayer. The product deserves 5 stars.
