One combination I regularly use is a few drops of Basic_H which is a Shaklee product my friend distributes. It doesn't hurt my plants and Edie has used it to water her plants for years. She says she hasn't had any buggs on her plants. I just left her a message so that I can find out the correct combination of Basic H to water for the plants benefit and the demise and prevention of bug infestation. She will be glad to hear from you and tell you about what she is doing. Let me know if you want to get in touch with her and I'll get you connected.
