I hate that I do this but I let my dogs out in the yard when the JWs are on my street. They don't like anyone coming near their fence and go nuts. Usually it stops the JWs from coming on the property but we had a brave one not long ago. I invited them into the vestibule where my MIL has huge pictures of Mary and Jesus hanging along with some other saints' pictures and a big fat crucifix. They looked around and hit the road pretty fast.
