What prayers do I say, or should I just sprinkle it around my room, would I need to say an exorcism prayer.
Here’s some info from the St. Pio Center for Deliverance Counseling - a powerful prayer you can say while blessing your home with Holy Water.
There are many more prayers in their Spiritual Warfare Prayer Catalog that you might find helpful.
Hedge Prayer for Protection of Household
[Edited]
Trusting in the promise that whatever we ask the Father in Jesus’ name He will do, I(we) now approach You Father with confidence in Our Lord’s words and in Your infinite power and love for me(us) and for our household and family, and with the intercession of the Blessed Virgin Mary, Mother of God, the Blessed Apostles Peter and Paul, Blessed Archangel Michael, my(our) guardian angel(s) and the guardian angels of our household and family, with all the saints and angels of heaven, and Holy in the power of His blessed Name, as ask you Father to protect our household and its members and keep us from the harassment of the devil and his minions.
Father I(we) ask in desire to serve You and adore You and to live our lives for You that You build a hedge of protection around our household, like that which surrounded Job, and to help us to keep that hedge repaired and the gate locked so that the devil and his minions have no access or means to breach the hedge except by your expressed will.
Father, I(we) am(are) powerless against the spiritual forces of evil and recognize my(our) utter dependence on You and Your power. Look with mercy upon me(us) and upon our household and family. Do not look upon our sins, O Lord; rather, look at the sufferings of your Beloved Son and see the Victim who’s bitter passion and death has reconciled us to You. By the victory of the cross, protect us from all evil and rebuke any evil spirits who wish to attack, influence, or breach Your hedge of protection in any way. Send them back to Hell and fortify Your Hedge for our protection by the blood of Your Son, Jesus. Send your Holy Angels to watch over us and protect us.
Father, all of these things I(we) ask in the most holy name of Jesus Christ, Your Son. Thank you, Father, for hearing my(our) prayer. I(we) love You, I(we) worship You, I(we) thank You and I(we) trust in You. Amen.
Now if you want to go all out, there is also the House Cleansing and Blessing. This one is really involved, I’d give the hedge prayer and Holy Water a try first.
If you still feel there’s a problem after that prayer, then I’d do the full house blessing, which you can do on your own, or you can have a priest bless your house.
At what point would I sprinkle the Holy Water? At the end of the prayer
You can sprinkle the Holy Water whenever - I’d do that either before or after the prayer; I don’t think it matters when.
reff… Lay persons should not attempt “exorcism”. That is something that only a qualified priest can do (I’m not sure if deacons can also do this. But I’m positive that Lay persons can’t).
However, it is perfectly fine to sprinkle Holy Water around your house. Here is a prayer that I use, when I do this:
“Heavenly Father, I ask Your blessing upon this home. In the Name of Your Son, Jesus… I ask for those who dwell here, to be delivered from sin and all evil influence. Protect us, dear Father… from sickness, accidents, theft and all domestic tragedies. I place this home under the Lordship of Jesus… and consecrate all who dwell here to the Immaculate Heart of Mary. May all who live here, receive Your blessing of peace and love. Amen.”
God bless.
