Southern AgThuricide BT Caterpillar Control, 16oz - Pint

Thuricide BT works really well if you stay on top of it—meaning you need to respray after it rains. I was able to keep vine borers away for a while, but eventually they got my zucchini plants.As for the bottle size, I actually disagree with those saying it’s small for the price. While it’s not huge, I have a decent-sized garden and it’s lasted all summer with some left over. You only use a small amount, diluted in water—I measure it with a syringe. I also found that using a good pump spray bottle makes a huge difference; coverage improved a ton once I switched application methods. There isn't a noticeable smell and you don't have to wait to harvest like other bug control methods. The catapillars have been absolutely awful this year, so overall, this is effective and economical if applied correctly.

I have used this product for years as a way to control army worms on my brassicas and leaf rollers on beans. Works quickly ( a few days) and it's not toxic to pollinators or my family.

It's BT spray, which I use to control cabbage worms on collard plants. Works by stopping up worms gut. They eat their weight everyday, but when they can't relieve their gut, they simply stop eating. Mix according to directions, and spray plant once a week for best results. Repeat spray after a heavy rain if needed. This bottle with make enough spray for a couple years.

Poor directions regarding how to mix, but seems to be effective product.

This stuff is FABULOUS!!! Every year I grow BIG petunia baskets (they get at least 4 feet in diameter), but it never fails, every year I get these pesky little caterpillars that love to just destroy my baskets...And it seems every year they seem to come earlier and earlier...As soon as I notice the first little bugger on them, I use this once a week, and it kills those little bast**rds and returns my petunia baskets to happy!!If you have the same problem, this is the stuff to get!

This product works on my broccoli, peppers, and green bean plants. You have to dilute it so much that it lasts forever.

I saw a few adult squash borers and after using this they are gone and my squash is safe with no sign of and stage if them. I highly recommend. Super easy to mix and spray on my cukes and squash plants with a hand sprayer

My Eastern Red Cedar is a favorite of bagworms. There were no problems until some nitwits cutting down a nearby Boxelder Maple dumped the huge stumps right next to the Cedar in my front yard, and left them there for several days. The damage to my lawn was bad enough, then later I noticed what looked like dinky pinecones hanging all over the lower branches. But cedars grow little blue berries, not pinecones. So what the heck were these things? A bit of research told me that bagworms will live inside the bark of Boxelder Maples. But with the stumps lying right next to the cedar tree, its pungent aroma attracted the bagworms like moths to a flame. I manually pulled off literally hundreds of bagworm sacks, which must be physically destroyed to prevent reinfestation. I noticed they had decimated the foliage on the lower branches. Literally stripped them bare. Bagworms will destroy entire trees if not eradicated. For months afterward, I kept looking for those little pinecone things, finding ones here and there once in a while. I was pleased to see the bare branches regrowing their foliage. Now I keep a lookout for not only visible sacks, but any indication of damage.Not content with simply removing the visible bags, I bought this anti-caterpillar product. The entire 20 foot tall tree was thoroughly sprayed several times, yet there’s still enough left in the bottle for a couple more applications. Over the summer, after spraying the tree in the spring, I noticed wasps investigating the tree for several months. Clearly they were searching for tiny insects and such, so I let them do their thing. Whether bagworms or some other pest, they were welcome to eat whatever they could find. Unlike hornets, wasps tend to be relatively docile. They aren’t interested in people or animals; they just want to eat every bug they can find.In spring, I plan to spray the entire tree every few weeks until I run out of product. This stuff doesn’t harm other insects, just bagworms and other unwelcome caterpillars. Anything hurting my tree by feasting on it must die! (Birds and rabbits and stuff are more than welcome to eat the berries, though. Bon appétit!)
