Evil simply cannot abide this scent and will not tarry in the vicinity where it is used.
Do an initial moderate cleansing of the area. Prepare the room by closing all windows and sources of ventilation. Prepare an incense burner with lit charcoals. Place a substantial quantity of Cast Out Evil incense onto the burner. Position the burner in the center of the room.
▪️Let it remain there for a minimum of an hour, and overnight at longest. While the incense burns, the room should be closed to all outside ventilation. If it's possible for someone to stay in the room, to attend the incense, they will be rewarded with a powerful personal cleansing. If this is not possible and the incense will be temporarily unsupervised, be extremely vigilant as to fire safety.
▪️When sufficient time has passed, open windows, provide ventilation, let the fresh air in.
Can also be sprinkled outside on all window sills and entry so that no evil spirits can gain access into the home.
