Bonide 8066 Captain Jack's Bacillus Thuringiensis BT Organic Worm & Caterpillar Control, 32 oz. Ready-to-Us - Quantity 1

I had caterpillars on my petunias last summer and nothing I tried to get rid of them worked. It got to the point that I just had to throw them out. When I saw those little buggers on my petunias again this year, my heart sank. I asked ChatGPT what I should get to annihilate the caterpillars, but not harm the bees. It recommended a Bacillus thuringiensis (Bt) spray, so I gave it a shot. It is smelly when you spray it, but it washes right off your hands with no lingering odor. After the first application, I have seen zero caterpillars and my planters are beautiful again. HA! Not today, caterpillars.

I have been dealing with bagworms for quite a few years now and after doing some research it brought me to this product. WOW! Talk about a quick working and effective spray. It was easy to use and got high up into the tree without me having to get out the ladder. The worms dropped instantly and I have not seem them since! I plan to use it next spring as well.

Good stuff. Caterpillars are gone!!

Worked great killing caterpillars on the boxwoods. Hand pump is a bit tedious for large areas. Best use a pressure sprayer to save your hands for all the pumping. Overall great product inside the bottle.

Great . I spray my cabbage 4 days and all worms actually starve and die . This is great staff . Other products are more expensive but this one worked for me just fine . The only part what I don't like is smell . It's smell horrible but as long as is effective it is fine for me . Easy application. Value for money is good .

Why did you pick this product vs others?:This is one of the best that I use that does not require protective equipment. It is easy to use. This quickly works and I can trust this brand. I have found that it works on all kinds of pests.

It’s our first year growing tomatoes and our plants were overtaken by tomato fruit worms. All of our leaves, tomatoes, and stems were getting eaten. After one round of spray, I already noticed a huge difference in the amount of fruit worms on our plant. I sprayed twice a week and after two weeks, I did not notice any more fruit worms and the worms stayed away so that I then began spraying once a week. The spray does have a bit of a smell, but it’s extremely worth it for getting rid of the pesky fruit worms. I am planting new tomato plants and am using this spray as a preventative measure as well.

Works as advertised.
