No more bagworms!
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!)

Great concentrate
Works well and it is long lasting. You need only 2 Tbsp per gallon. You could make it more concentrated if necessary.

Natural & Organic Control - Southern Ag Thuricide BT Caterpillar Control
I applied this to my lawn area and garden beds with my spray tank to help to reduce the Japanese Beetle attacks on my trees and plants this year. I'm also hoping that the BT bacteria in my garden beds and lawns helps to limit the number of eggs that these beetles' law in my lawn are killed when they develop into grubs. I like that this is a natural method of controlling beetles and grubs that don't use chemicals in my garden and lawn. It may not provide the quick kill that a chemical insecticide provides, but BT is safer for me and the environment.

Great for catapillars
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.

You Garden Savior, I guarantee it 100%!!
Bt has saved our vegetable garden!! This product works the most effective for what it does more than any other garden pest product out there! This is our 2nd season using Bt in our garden and it has worked AMAZINGLY at keeping the caterpillars & their damage gone, I'd say about 99.5% gone. Bt concentrate is on the pricey side but it's 100% worth it and the little jug lasts us almost the entire season since it only requires 2 teaspoons per half gallon sprayer, plus it's odorless. I also mix it with our other pesticides in the same sprayer. My go-to concoction that has saved our garden is Bt, Neem Oil and a general multi-insecticide that I rotate between a few (Dead Bug & Marathon) and I add each of the concentrates into the same half gallon pump sprayer, fill with water then apply throughout our garden. Before discovering Bt, there was a moment we considered throwing in the towel with our home garden because of the amount of insects & damage we had and nothing else was working. Thank You Bt for saving our garden! ♡
