It turns out that there are no books containing any substantial information on poltergeists. This shouldn't surprise me. Peeves came with the castle and no one knows what to do with him. But he fears the Baron, which as we all know is about the only leverage you can use against him.
I think, though, that the key to dealing with Peeves, and perhaps any poltergeist, really, is to earn their respect. I certainly don't think I'm that good, nor do I really care if I have Peeves' respect. But I do think fighting fire with fire could prove beneficial here. I am a Marauder, afterall.
So I tried it. Next time you see Peeves, ask him how the pepper's working out for him. Of course, he probably won't answer amidst the sneezing.
Oh, I'm glad it worked! Peeves won't know what to do with himself, now the prefects are fighting back! I don't know about earning his respect, but I like the idea of fighting fire with fire. I'll keep that in mind the next time he inhabits one of the suits of armour. He's already scared four first year girls witless with that one.
