Satisfied, hoping label will disclose bee info.
Worked great. Caveat: I'm not sure how or if this product affects bees. It definitely worked on killing cabbage moths but after I used it, I got concerned about bees. Please research that question before using this product. I used this on my new Butterfly Bush which cabbage moths were destroying. The plant recovered from all the damage (many holes in its leaves). Next year I may try purchasing lady bugs to try to remedy the moth larvae problem. But I will also research whether or not this product is harmful to bees and whether the chemical ends up in the flowers (the chemical is sprayed on leaves). This year it saved my plant....

Monterey BT Spray for Organic Gardening Works Well
Monterey BT Spray is essential to use on my petunias. This helps to prevent little bud worms from eating holes in the flowers.

Bud worms are history!
I had bud worms chomping away at my petunias, but this spray did the job. Those worms never stood a chance. They are gone and my petunias are starting to bloom again. Love this product!!
