For those that recommended Bayer Tree and Shrubs, you really gotta hit them up with a high dosage of IMID, or else, whatever aphids that survived will build an immunity to it. I've tried them with mild to low dosage, and still see them moving, and eventually stepped it up to the higher dosage of 18-20ml per gal, by then it was too late. Hit them hard with the high dosage right away, if you're anywhere after about 1-2 weeks in veg with the clones being 6 inches in height or taller, it should be strong and healthy enough to take a pretty high dosage of Bayer anyways. I made the mistake of not going strong enough and only treating some of the girls in the rooms, and ended up having to go all out and used the Bonide. Again I wasn't thorough enough with the Bonide and only used it for part of the rooms, and now I have to deal with these little fuckers again. But for what it's worth, for the girls that was flooded with Bonide showed the best results. The main ingredient is Acephate, which I believe is the same stuff found in Orthene, and it kills the aphids on contact. So for those that are dealing with it right now in veg, I'd recommend you use Acephate in veg or at very very early flower, and then use organic or natural predators throughout flowering to help keep the aphids population down to a tolerable level, or at least to help make sure they're all gone from the Acephate. I don't know how you guys grow or what mediums, but I mixed the Bonide to the recommended ratio/dosage, plugged up the drain holes in the trays, flooded the entire tray with the acephate solution and let it flood for a hour. While the tray is flooded to about half the height of the rockwool cubes, take cups and pour the solution into each cube to make sure you're flushing the solution into the cubes too. Release the drain plugs and let the solution drain out into res. Clean the res with bleach and scrub it clean, put it back and then flush the flooded girls 24 hours later or the next day with just water and hydrozyme. Keep in mind that you want to do this after the girls are not hungry, so you'd have to give them regular food and nutrients, so they eat as little of the acephate mix as possible, so I'd do it a day before you're about to do your regular res change/clean anyways. And then monitor the mediums for any survivors, I've found this stuff to kill the aphids on contact. When you go back to your regular feeding regiment, be sure to lower the PPM by a few hundred and keep using Root Excellurator as part of the regiment to help repair damaged roots.
Good luck guys
