Dear David,
 
Get out of there!!!   Get to a safe place.  I am praying that God bind your enemies.  I know of another family that felt they had to flee because their street became inhabited by several satanist.  They moved to a undeclosed location.  If the local police have some on their force, and if the churches in your area are not strong in the Lord, and you have no support, then time to leave.  That may be God's way of getting you to another area and allowing His judgement to reign in on that area.  Let Him clean it up.
