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.

Worked, I think.
I used Bonide Captain Jack’s BT on my bell pepper plants and lettuce after seeing signs of caterpillar damage. I followed the instructions and sprayed a few times, and I didn’t notice any more caterpillars afterward. So, I think it worked — though I didn’t directly see the effect on the pests. One thing I didn’t like was the smell. It had a weird, almost “spit-like” odor, which was a bit off-putting, but it wasn’t unbearable. On the plus side, the spray was easy to apply, and I felt good knowing it’s safe for organic gardening and beneficial insects. Overall, the product seems to have done its job. I’d consider using it again, but the smell could be a downside if you’re sensitive to that sort of thing.

Keeps the caterpillar off. Definitely great to have in your garden arsenal
Thank goodness I came across this. My lettuce was getting devoured until I treated it with this stuff.

Works great
This is THE ONLY SOLUTION to my yearly caterpillar invasion. Unfortunately it's hard to find in my local stores.

healthy Bacteria to the rescue!
I have a ‘Grape Kool-Aid tree’ (Texas Mountain Laurel) that’s about 4 years old. The caterpillars absolutely adore the fresh new growth so this year I got the Bacillus Thuringiensis to apply before I see them as well as IF they get on the tree after I’ve sprayed it. Although the caterpillars don’t kill the tree, they’ve stunted its growth in the last 2 years. This year I have a NATURAL secret weapon and have high hopes if not this year, maybe next year I can get a few wonderfully scented blossoms…
