Hi, I'll check it out,thank you... always something to learn, I've been using dish soap and water for years, spraying on plants, contains alcohol ...lately used rubbing alcohol in a small sprayer to get rid of white flies on my mandarin tree, had to spray daily for about 5 days before they got the message. :)

DE works great and I've been using it for years. The only drawback is that it needs constant reapplication, especially after a rain, and that gets expensive. You must use food/horticultural grade DE. I figured I'd save money and use the extra DE when we had our pool filter changed but was told that type is a carcinogen.
