Don't get the home "blessed". It is simply not addressing the problem. More times than not it will agitate the spirit(s). There may be a "right" the spirits have to the home. You need to contact a church, but not for a blessing. You need to have someone who is spiritually mature come and remove it and teach you how to keep it clean. What denomination you talk to doesn't matter, they just need to understand their spiritual authority over such spirits. You may need to do some "shopping around", but start getting a hold of some churches.
