My suggestion, if you really do have something in your house, find someone powerful to get rid of it. You, yourself aren't going to be able to. Personally, I use a mixture of religions, so that might be an option as well. Find something that speaks to you. If Moloch were still here, I'd say go to him. You might try Muerte, he seems to be a bit more tolerant, but I don't know. And as for demons.... if this is your attempt at hunting them, you seriously need to get a new hobby. You can't go off half-assed and expect to not have your balls handed to you in a Wal Mart bag. I'd wish you luck, but I have intention of wasting it.
