yeah when I counted 8 in a minute on one of my plants, I freaked and thought they were all over, after the first spraying, next morning I counted 1 total (out of all 4 plants), next day of spraying, couldn't find any... get the point? I also turned up my fans so when the adults try to get to another plant, they are blown far away (just took them one at a time out of the room and set a 20" box fan blowin' on them, you see them fly up and they get blown "bug miles" away from their target.

Or try that mix, and use a cotton swab to dab them with the mix, it kills them instantly, they turn brown and disappear in hours, but I think spraying the soil is key to control.
