Below are several spells that can help you.

A Spell of Protection:

You will need a small, black, cotton pouch or sachet-preferably with a drawstring tie. On a Saturday evening, during the waning moon, you should draw a pentagram in black ink (India ink works best) on a small piece of parchment. Roll the parchment and place it in the bag.

Next, you should place in the pouch the following ingredients:

a small clear crystal
a full pinch of sage
a full pinch of wormwood
a small piece of lead (a lead fishing sinker will work)
a strand of your hair
Tie the bag using three knots. Carry the bag with you for protection.

House Blessing:

You will need:
1. Salt & Water
2. Incense
3. Milk & Honey
4. Oil
5. Wine
6. Bells, Pots, Pans, Whistles, etc.

Cast a circle in the main room and after casting, visualize the circle expanding to include the entire house. Call upon the spirits and energies living in the house (or apartment). Invite those who will be harmonious with the new household and its energies to remain. Invite/ask those who will be happier elsewhere to depart. Release all “energies” not compatible with the new household.
Note: This may be expressed as a “release” in order to unbind anything that may be stuck.

Then call upon, greet, and invite ancestors, patron deities, and all harmonious spirits and energies to dwell in the house as they please.

Gather up the pots, pans, and all the noise-makers. Go to each door and window, not forgetting the fire-place and dog-door, making as much racket as humanly possible–to drive out the unwanted.

Go again throughout the house and at each portal (door, window, etc.) sprinkle salt-water and incense, saying: “By the Elements I purify and charge this portal.”

Then anoint the portal with milk and honey, saying: “By Milk and Honey I ensure prosperity and peace within this place.”

Finally, anoint the portal with oil, saying: “With Oil I seal this portal and protect all within.”

At the front door a special prayer is said, asking the guardian deities to freely grant entry to all friends and loved ones, and to prevent passage (turn aside) to any who would do harm.”

Then, if it’s a house–pour wine across the width of the threshold; if it’s an apartment anoint the threshold with light touches of wine.

The house-holders then each take a sip of wine, leaving some as an offering to the Gods, and the Circle should be closed. The remaining wine, milk, and honey should be offered to the Gods which can be accomplished by pouring over the ground.
