It can be a simple task to make a demon trap for you home. This device will trap incoming negative entities before they can disrupt the harmony of your residence.
Take a white piece of paper. When you wrote the following words on it, write them in a spiral, leading from the outer edge to the center of the paper.
Write: " All you spirits of disruption and disharmony, into this trap you are drawn. From the center you can only return to your orignal domain."
Place this flat under the rug by the front door. If anyone enters with such creatures in their wake, the "demon" will be trapped at the door. This was a very ancient device used by the people of Mesopotamia.
I use this at my home. It works very well. Some people when they have come into my home and felt overwhelmingly sick after they step on my mat. But once inside, they feel very relieved and like a huge weight has been lifted off of them.
I got this from the book "Moon Magic(K)" by D.J. Conway
