Expanding on Azamax. I have a 125 gal. fish tank. I used to put plants on top of it. I used to spray Azamax on the plants. No problem. No other insecticide I have seen can be used near fish. Mahatma Gandhi ate a bowl of Neem porridge everyday of his life. The only bugs I have right now are my fault. I have 0 whitefly, 0 spider mires, 0 scale, a few fungus gnats and some mealy bugs. If you do succulents, mealy bugs are your #1 enemy. My fault because I was in a hurry, gave the plants a quick glance and decided they are fine. Did not do the preventive spray that I should have. Azamax works. I only recommend things I have first hand experience (for over a year) with. Gene
