We had these nasty guys a few years ago.  Tried everything (diazinon spray, 
washing & repotting, moving, etc.)  Even when they went away briefly, they 
always came back.  But I refused to let go of the whole collection.

Then, we moved.  They've left and they have never returned.

 Moving may be a drastic measure (!) but I think these are some of the 
differences that helped:  LOTS of space between plants (better air flow), LOTS 
of indirect light (healthier plants), summertime spent outdoors for most of 
the houseplants, less frequent watering for most plants.

 Or then again, maybe it was the ladybugs that moved in with us!

Good luck!
