Systemics for Aphids?

Hi all,
I appeal to the collective wisdom of this forum once more, as I am continuing to deal with an aphid problem. It was largely abated due to Imidacloprid granules that I had been watering in, coupled with our good weather up until recently, but the latest spike in temperatures have brought them out in force.
Plants that have been regularly dosed with what I thought was plenty of Imidacloprid are showing active pockets of the critters, and in some cases they are doing enough damage that I've had no recourse but to risk over-doing it by dosing them up strongly a second time. I see no ill effects on the plants, as of yet, but I am starting to consider the possibility that either this stuff doesn't work as well as I need it to, or they are becoming resistant over time.
Is there another systemic I can get in granule form that can be watered in and will work? I'm thinking perhaps a rotational program would give me more bang for the buck. If nothing else, maybe something else would kill them quicker? In this heat, I am watering almost daily unless overcast or on the off chance we have a forecast of rain. This may be contributing to the lessened effectiveness, I realize, but it's a no-win situation of sorts.
Trying to keep ahead of it before anything gets too badly chomped, but I'm already seeing more activity than I am comfortable with. I definitely can't spray anything in this heat, given the horrid leaf burn I've had in years past, so granules or at least something in liquid form that I can water in, would be ideal.
Any ideas for a readily available systemic that might help where Imidacloprid is letting me down?
