Review: 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.
Review: 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.
*by R***. on December 29, 2025*

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.
