Hmmm, bee-nuts. Here in central WI, we have a huge Asian beetle problem, which were brought in to control soybean aphids. No problems with soybean aphids now, just a HUGE population of Asian beetles once it freezes and the soybeans die back, leaving the beetles nowhere to live.
One other way to kill aphids: Take 1-2 cups of tomato leaves (I strip the bottom leaves off my plants anyway) and chop up finely. Add 2 cups water. Let steep for 1 day. Strain into a spray bottle. Spray affected plants. This is also supposed to attract beneficial parasitic wasps that prey on other garden pests.
I haven't tried this yet but just brewed up a batch and hope it helps! Obviously, you wouldn't want to spray this on anything you intend to eat soon...
