fyi, azasol is water soluble so kicks ass x6. 60,000ppm brosephYellow Sticky Traps for identification and small pop. control, then it's Azamax spray on the medium surface to get the ones that chill there down, after that I use Azamax in the res and that kills off the buggers! I have read that Vaseline around the stem base helps the babies that are hatched, and start life around 1"-2" deep around the main stalk, from being able to take those first steps up the plant stem out of the medium. Love me some Azamax.
