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

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!

This worked really well for caterpillars on my petunias. There were so many of them and I was trying to remove them one by one. I sprayed my plants/flowers one time and no more damage to my flowers. Seems to have solved the problem. I would just be careful to not get it on yourself, cause it stinks! Def recommend it.

I am an indoor gardener who struggles and struggles and struggles with fungus gnats. This stuff works to kill the adult bugs as they come out of the soil. It works very well. It’s easy to use. The only way I have found to deal with the fungus gnats on my indoor plants is to use this for the adults, and then use the pellets that absorb into the water to kill the larva. I can’t remember what those are called, but these work great for the adult bugs. Recommended!

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.

My cabbage was always full of holes until I read about cabbage moths ( which I now realize I have in abundance), and purchased this product. No doubt, in five years they will come out and say it causes cancer, but for now, my cabbage is beautiful.

I had slugs and black worms eating the white petals of my daisies. I sprayed them and they fell off. One was a huge slug. It worked! I unfortunately sprayed my blueberry bush as was too close to daisies but later found off I only have to rinse the blueberries and are safe to eat. I really like this spray!!!!

This is the one you want for your tomato plants. This rid my plants of those nasty caterpillars and was not some awful pesticide. You can eat the tomatoes afterwards (with a rinse).

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.
