Works for powdery mildew
This did a great job getting rid of a nasty bout of powdery mildew. Now that I know that it works I will be using it in the future as a preventative for powdery mildew and I felt it helped keep pests at bay, especially ants lurking on leaves. I truly hate the smell but don't care as long as it does its job. Didn't linger on my produce itself either.

Very effective against hornworms!
This product saved my tomatoes! Hornworms have been bad in Texas this year. I was searching my plants every day for these nasty creatures and going out at night with a blacklight and still having hornworm damage. I started using BT on my plants and overnight found it had killed several hornworms. It is important to me that what I use is non-toxic to pets and beneficial insects. BT does that. The smell is a bit strong, but it dissipates relatively quickly. This is good stuff! I highly recommend it if you're having caterpillar issues in your garden.

Fast and effective.
My basil plant was under attack by Thrips and was able to eliminate that threat and then caterpillar (cabbage loopers) infestation. As soon as the Captain Jacks’s arrival I treated the basil and in one to two days I noticed dead and dying Cabbage loopers. All destruction stopped within a few days. Very effective.

THIS WORKS!
I noticed all my bougainvillea looking sickly, with half eaten leaves and webbing in and around on just abt every leaf and bract. I have never had this happen before. Looked online for the best solution and this product’s ingredients came up. This worked with one application. These caterpillars were a light green and incredibly mobile. Afterward, dull and practically lifeless. I will be using this at the first sign of infestation. Great product! Highly recommend.

Didn’t work well
It’s not working very well for me. I spray the plants at night but the bugs are still eating my plants. I’ve tried others as well as this which didn’t help to get rid of bugs.
