## Description

Bonide Captain Jack's Bacillus Thuringiensis BT, 32 oz Ready-to-Use

Review: This stuff works!! - I didn't know exactly what to expect. It's my first time trying to grow tomatoes. I didn't think hornworms existed in my area of the country, but there was massive evidence of something eating my plants. (Frass, and lots of it.) Anyway a quick research session led me to this product and I am very much a fan. It could not be easier to use, and the results were evident within only two (2) days. The fact that it is organic and will not harm bees and other wildlife was a huge selling point for me as well. I believe the price is more than fair, as I later compared it to other sellers. I also purchased a blacklight so will be better equipped to stay ahead of the game in the future.
Review: 10/10, only one time, only one result!!! - Worked great! Had a slight caterpillar problem on my gigantic basil plants. Sprayed this, only took one session and they were gone within a week. worked like an absolute charm!!!

## Questions & Answers

**Q: Will this kill squash vine borers?**
A: I've read that it has to be BtK for it to kill SVB

**Q: Amazon's highest rating (4.6) for this type of insecticide, and it is very popular. Do you agree that it is very effective for tomato fruit pests?**
A: Yes it is.  It's hard to find in stores anymore so Amazon is best source.  It works and maintains organic qualities.

**Q: Just curious as to why the info says "Approved for organic gardening" as opposed to simply "organic"! And who approves it?**
A: Because it’s safe to use in a organic garden.

**Q: Will this work on bud worms?**
A: Yes.  You should start using it before you see damage and then regularly every two weeks to keep them from taking over your plants.  Worked great on my supertunias last summer.
