I have always had a problem with these pests when I bring a few boo's in the house for the winter. I tried some stuff from Gardens Alive which did absolutely nothing. I resigned myself to sucking them up with a Dustbuster and letting the plant dry out a bit. Then, I happened to water one day with miracle gro and lo and behold it got rid of them! I haven't any since I used the stuff. It's amazing how well it worked, try it out and let me know if it's a fluke or not.
