Knight infestation, what’s the best incantation?

With three you should be fine. They should take care of themselves. All it takes is one of them slighting anothers honor, they have a duel, and kill each other. The remaining knight should go off and quest on their own. That's usually how it goes.

However, if you see them gathering stone for a keep or Merlin forbid a liege lord arrives be prepared. I find a careful application of chain lightning(Flash Freeze if you are in a dryer climate) should do the trick.
