1 teaspoon per quart of water sprayed between rains controls cabbage worms
This saved my leafy greens! 1 teaspoon per quart of water in an electric sprayer. I grew many varieties of leafy greens this summer, mostly from the cabbage family, and cabbage worms were devastating them until I got this product. Those darn worms are nearly invisible until they've eaten through all your leaves. I had a planter full of watercress that was reduced to nothing but stems, and after picking off the by then large green worms and spraying the remaining leaves and stems as well as soaking the soil with this diluted product, my plant came back healthy and happy. At various times, the worms also attacked my arugula, all the different kinds of mustards I was growing, my nasturtiums... pretty much everything. Given that my plants are up on a second floor balcony, I was kind of surprised by this, but I had to fight these worms off all summer long. I did find that I needed to use this repeatedly, basically every time it rained, and sometimes even during periods of drought. It's definitely not a one-time cure--you have to be vigilant about it. The worms start out so small they are practically invisible, and even when fairly large I have trouble seeing them on casual inspection. I dilute 1 teaspoon of this in a quart of water and put it in an electric sprayer. I find that manual sprayers tire my hands too much for the amount of spraying this requires. First I turn over the leaves and spray their undersides. Then I spray the tops and finally the soil. Whatever is left after treating the plants I use to water the soil. The best thing for pests would be to use netting that doesn't touch the plants so the pretty little "butterflies" can't lay their eggs, but for my container plants that is really impractical. That works more for people growing in the ground in beds or rows. Unfortunately, this seems to have no effect on aphids, which I am now battling. I do have a ton of this left, even after using it all summer on a small porch garden.

Absolutely needed for my petunias
I had researched what I needed to keep the bud worms from eating my petunias , and was recommended this, it works great , my flowers look beautiful this year. This BT spray is a very small bottle , but you only 2 ozs per gallon mixed with water , and I spray my flowers using a gallon pump sprayer , so much easier and good coverage , you don’t want to mix up too much at a time because you don’t want it sitting in too much heat, so I pretty much make up what I’m just going to use so I’m guaranteed the effectiveness of it. So the bottle is small but goes along ways , totally worth the price . I spray at night only when there is no sun, I make sure I first the buds and the soil inside my flower pot, without this product , my petunias would have been eaten by those nasty bud worms , this is a great product and I would recommend this to anyone who wants beautiful petunias!

Quite surprised
When I applied this product to my cabbage, it seemed to just roll off like the cabbage was water proof. So I wondered how could it possibly do anything to stop the worms from eating it. But as I harvest to make sauerkraut, I'm seeing the cleanest cabbage heads I've ever pulled. You can see a few holes in the leaves here, but they were there before I sprayed the product on . After I sprayed there were no new holes, and when I harvest, there's no sign of loopers in the heads. No slugs or earth worms either. This little bottle of BT is concentrated so I should get at least 4-5 seasons out of it, because I only used about a liter of spray this season. That includes using it on broccoli and cauliflower, and a few flowers that had leaf miners. I should say, this product is not intended for aphids and leaf miners, but it seems to work on them.

Works on squash borers
I suppose it worked, I’m a newbie gardener and found squash borers on my squash plants. I used this and my squash kept on growing and producing and I didn’t see any beetles or larva. The instructions are clear, it’s easy to apply. A little bit goes a long along way, so this tiny jug will last me for a long time! Don’t be underwhelmed by the small size of it, unless you have a massive garden this is plenty for home gardeners.

Fungus gnats too (update: maybe?)
Though they're not a caterpillar, it cleared up fungus gnats in houseplant soil in just a few days by attacking the larvae. Update 3/24/15 Well, I'm not sure if it went bad, got too cold during shipping, or what, but it's not really working for me any longer against fungus gnats after a generation or two. I guess they can develop immunity? It seemed to work really well after the first application, but upon reinfestation from a different pot in the house they gnats aren't seeming too bothered by following applications despite drenching the soil in bacterial culture. Developed immunity? Not sure, but it's not taking care of my fungus gnats any more. I only tried it because i heard it was helpful, so I'm sure it works for some people out there. Try not to get it delivered in the cold, and hopefully you'll have better luck than me!
