All - What is a polite yet effective way to get rid of JWs?

Just politely tell them to put you down as a do not work home, or put no trespassing signs up and we will walk right pass your home. And just so you know if they had a meeting that night-you would've been more than welcome to attend however; Jehovah is not trying to keep no one who doesn't want to be kept. We do our work out of love for God and neighbor, and we are looking for person's who want to hear God's word.
