This is a great interview/discussion with Fr. Chad Ripperger regarding spiritual warfare and how to use certain prayers to deal with demonic oppression/obsession/infestation.
I encourage you check it out and get his book titled, Deliverance Prayers For Use By The Laity. It’s in multiple languages now.
The goal is NOT to pretend your an exorcist and go after the demons by yourself. DO NOT do that. Follow Fr. Ripperger’s advice on this and you’ll be able to better combat the evil spirits plauging your life (as well as the lives of those under your familial authority).
For another website that has some of those prayers, check here.
