A little extra protein. I don’t like to use insecticides, either. I was told that spraying a mild soap solution - 1 tsp. per gallon of ordinary dish soap - would help keep bugs off my bell peppers and it seemed to be helping when I remembered to do it!
We just learned that dragons will eat tomato hornworms, so I know what to do next year!
I’ll try it. It’s either that, or put on my Halloween mask and try to scare them.
