I've just brought all my plants inside for the winter. I washed all roots and repotted (most are Brugmansia trees). I currently use a 1000W HPS and a 1000W MH bulb in a room 10'x10'. My problem is that, in creating an environment for these trees, I've also built a home for billions of aphids, and maybe hundreds of spider mites (haven't counted those..yet). I went through 1L of end-all insecticide today. It worked for short periods last year, but I have at least triple the foliage this year than I did last. What can I do? I need to eliminate this threat before I go batty. Has anyone had any success with predatory insects? I ordered a bunch of ladybugs a month back, but they all flew into the lights and died. Kinda funny, but not very effective. Please, if anyone has any ways of killing the bugs once, then their larvae, then preventing them from coming back, I would be internally/eternally grateful. Thank you much.
