Beautiful fine mist spray for cut worm control
My beautiful pepper plant just disappeared in my garden. Only planted the start a week ago. Happened last year also. Investigation: cut worms right at ground level and you'd never know that plant had been there. THIS SPRAY controls the cut worms. Coffee grounds and crushed egg shells surrounding the plant is helpful, but this spray I believe will work much better and save my garden .My garden is ALWAYS organic, I use companion plants and other plants for control and enhancement. This is organic and welcome.

Healthy products for healthy plants.
Specifically used to help with vine borers. Much safer and effective product than others I have tried and/or researched.

caterpillars gone, mountain laurel saved!
I used it once and haven’t seen a caterpillar since. Very effective. It was easy to use and sprayed widely. I didn’t love the smell but I think that comes with the territory.

Solid product with consistent use
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.

Worked on contact
Never seen these worms had to look them up. It was in my apple trees. Haven’t had a reinfestation I live in rural Texas so there’s always bugs everywhere. A few little sprays was all it took. This works absolutely great and you get a great amount for the price you pay it’s an absolute buy again for me.

Works on cross stripped cabbage worms
Had really bad infestation of cross-striped cabbage worms on my Brussels sprouts. Attempted to use diatomaceous earth and hand pick (which only slowed them down a little) until this stuff came in. I sprayed this one day on tops and bottoms of all leaves. Same evening it rained hard so I applied again the next day. It has been 4 or 5 days since application and I haven’t seen a single caterpillar left! This stuff works! Picture of my almost destroyed Brussels stouts. Thankful for Bt!

Works great! Wormless corn!
No bugs on my corn! No worms or anything. Be sure to read when to apply. Got healthy corn and the price is right. Love its a natural product.
