I picked up this stuff at a local hydroponics store a few years ago to keep bugs off my Cannas. It worked wonders!!! Something had started chewing on my hops, so I mixed some up and sprayed them a few weeks ago. No more issues for the time being but I may need a bit more in the future.
It is 100% Vegetable based and is a foliar and systematic insect control. It is a repellent, antifeedant, and Insect Growth Regulator (IGR). It comes in a plastic jug that resembles a miniature Star Stan. You mix it per instructions and spray it on your plants. It works great for veggies too. I would recommend it if you are already having issues like I am.
