But if you have a plant that's sustaining caterpillar damage, this is the most specific spray available to combat only that pest. In organic gardening, specific is better since you're only killing the pest that's a problem and not the bees and beneficials in the garden.
I've been using Bt for years on roses and fruit trees with caterpillar issues. It's always preferable to just replace any susceptible plants with a sturdier variety, but if you have one or two that need help, this is the way to go.
This was my mistake. I should have immediately researched those things. Since they use the tree or shrub they're in to make their "case," they blend right in. Within months those few bagworms(I have since learned) had, to my horror, turned into thousands unnoticed. The shrubs were absolutely covered and were emitting an ominous white noise (due to the bagworms moving and munching on the shrub).
This product killed all the bagworms within a couple days. They're all still attached to the shrub, but they're dead. The smell is rather foul. Think thanksgiving gravy from last year. It made me a little noxious when I first opened it, but it doesn't bother me anymore.
I don't know if the shrubs are going to make it. If we get new ones, I'll apply this stuff often.
Now I don't know for 100% sure if it is the every three day hard spraying with the 16oz spray bottle, perhaps knocking the newly layed eggs off or it is the BT alone or a combination but whatever it is ... it works!!
Using the directions on the bottle and a hand held sprayer, I applied it to my heavily infested plants. 12 hours later . . . ZERO live caterpillars! The broccoli really took off and grew once the bug pressure was gone.
The BT kept the worms knocked down for about two weeks until the next generation of cabbage moth worms hatched. Then I reapplied with the same great results. I will never stop using this product.
