YOU KNOW WHAT actually, they have a scripture in Doctrine & Covenants that says if you offer you hand to an evil spirit, they won't shake it. Missionarios always start out with the handshake, so once I kept my hand by my side and said, "I'm sorry, I can't shake your hand." They got THE FEAR and immediately left. Exmos know all the tricks!
Alternately you could just send the very clear message, "I am not interested. Please leave and never come back."
