Wow... that sucks!
Personally, I never met a pesticide that didn't disappoint me. But I only used the lame soap or neem or whatever... still it turned into a never ending cycle of mess your place up seriously with sprays (think my living room) and repeat, repeat, until you'd rather chuck those plants in a hole in the woods and forget it.
Meanwhile, aphids are just a curse. What was mother nature thinking???
