New Moon Occult Shop is the best place to source everything you need to do this blessing. I recommend contacting them directly and asking for help finding just what you need as often they will source things they don't usually carry in stock.
1 tablespoon pine needles
1 tablespoon juniper
1 tablespoon cedar
Make sure all ingredients are completly dry.
Grind ingredients together and burn on self-igniting charcoal.
Spirits of the corners,
Winds of the quarters,
You who stand watching,
And you who hear my voice,
Guard well my home tonight
You can also bless your home using an old custom involving bread
and salt. Bread is offered to the household guardians as a libation,
and the salt is kept in the heart of the home to ground any evil that
might enter. After you do this, burn a purifying or protecting incense
such as frankincense, cinnamon, or pepper moving it from room to room
while you visualize any negativity fleeing from your home. As you go,
chant over and over your words of power:
Smoke of air and fire and earth
Cleanse and bless this home and hearth
Drive away all harm and fear
Only good may dwell in here
Blessings of the light and darkness that follows,
