Based on my own experience, as well as some ideas I would really like to apply, I have compiled a list of suggestions that can serve the purpose of greatly irritating the enemy and remaining in the light of grace of our Lord and Saviour.

1. Memorise biblical verses of protection. Some particularly useful ones include:
The Lord will rescue me from every evil deed and bring me safely into his heavenly kingdom. To him be the glory forever and ever. Amen. (2 Timothy 4:18)
But the Lord is faithful. He will establish you and guard you against the evil one. (2 Thessalonians 3:3)
God is our refuge and strength, A very present help in trouble.
Therefore we will not fear, though the earth should change
And though the mountains slip into the heart of the sea;
Though its waters roar and foam,
Though the mountains quake at its swelling pride. (Psalm 46:1-3)
The Lord shall preserve thee from all evil: he shall preserve thy soul. (Psalm 121:7l
2. Develop a Christian phrase that can be repeated regularly. My favourites are:
Jesus saves me. (This cannot be refuted as it is a timeless present tense for “everyone who calls on the name of the Lord will be saved.” (Romans 10:13))
I am for Jesus. (This is a double edged sword against darkness for it indicates that your will is aligned towards Jesus. It also shows that you belong to God. Very effective.)
3. Prayer to be almost constantly on your lips or in your mind.
The Lord’s Prayer.
Our Father, which art in heaven, Hallowed be thy Name. Thy Kingdom come. Thy will be done in earth, As it is in heaven. Give us this day our daily bread. And forgive us our trespasses, As we forgive them that trespass against us. And lead us not into temptation, But deliver us from evil. For thine is the kingdom, The power, and the glory, For ever and ever. Amen.
St Patrick’s Breastplate (partial)
Christ with me,
Christ before me,
Christ behind me,
Christ in me,
Christ beneath me,
Christ above me,
Christ on my right,
Christ on my left,
Christ when I lie down,
Christ when I sit down,
Christ when I arise,
Christ in the heart of every man who thinks of me,
Christ in the mouth of everyone who speaks of me,
Christ in every eye that sees me,
Christ in every ear that hears me.
4. Play hymns, prayers or an audio-bible on multiple devices in many rooms. This will certainly irk any unwelcome entity, particularly if you leave it on a constant, low volume if you need to have a break. A choice selection includes:

5. Some practitioners believe that the walls and ceiling should be washed with salty, blessed water. Other resources regarding house cleansing can be found here:

With glee I seek to irritate the enemy, in the hope to make the home environment as uncomfortable as possible for it to ever reside within. But I do so under the protection of Christ and without hatred.
