Plead the blood of Jesus over your house & property lines. Over your family. Put anointing oil over your windows & doors (except one). Then pray with others in the Spirit over your house, in your house, asking God what to throw away. Throw every ungodly thing out of the house (pornography; demonic music, games, movies, etc...; idols, accult material (books, gadgets, etc.) voodoo dolls, etc...) whatever the Holy Spirit shows you to toss. Then obey the Lord.
Then agree with the others, of Gods extra Angels on guard in your house. Then thank God for protecting you & yours. Send out any demonic spirits out of the one window without anointing oil by the power of Jesus Name. After all demons leave, then annoint the last window. And claim that as for you & your house, you will serve the Lord.
