I AM SO SORRY THIS TOOK FOREVER TO ANSWER! I really wanted to write out a good list and I just had a lot of work and personal stuff. Sorry! Anyway, I figured I’d take the time to list everything I could to help remove unwanted or following spirits.
Herbs - Angelica, Basil, Beans, Black Pepper, Clove, Cumin, Devil’s Bit, Dragon’s Blood, Elder, Fern, Frankincense, Garlic, Horehound, Horseradish, Juniper, Leek, Lilac, Mallow, Mistletoe, Myrrh, Nettle, Onion, Pine, Red Clover, Rosemary, Sea Salt, Thistle, White Sage, White Sandalwood, Yarrow.
Please research any herb before using as they can be poisonous to ingest or handle with bare hands. Many of these herbs are meant to be used dried or specifically just roots, leaves, or berries. Place any herb or combination of herbs and amulets in a witch bag and hang above doorways, sprinkle in corners (when safe for humans and pets), or carry on your person.
Stones - Amethyst, Black Onyx, Black Tourmaline, Botswana Agate, Chiastolite, Citrine, Fire Agate, Flint, Hematite, Jade, Lapis Lazuli, Lepidolite, Malachite, Obsidian, Pyrite, Selenite, Serpentine, Smokey Quartz, Snakeskin Agate, Sulphur (toxic when raw), Tiger’s Eye, Tourmalated Quartz, Turquoise.
When using stones, the hardness typically affects the ways they should be cleansed or even what stones they work best with, so definitely read up on them. Like the herbs, they can be kept on your person or added to pouches and left in a space that needs it. I think they work most effectively when kept on yourself or even worn in jewelry, just personally.
Symbols - Cross,Pentagram, Evil Eye, Hamsa, Horseshoe, Crescent Moon, Celtic Cross, Devil’s Snare, Eye of Horus, Seal of Solomon, The Sun, Thor’s Hammer. Celtic Knot, Anchor, Ankh, Goddess/Mother Earth, The Traveler, Witch’s Knot, Besom, Arrow Head.
Realistically the list goes on and on. I do not recommend using a symbol outside of your faith system, especially if it comes from a closed religion or even if you do not know much about it. I also do not recommend using any symbol that does not have a personal connection to you in some way (so not using something for the heck of it etc). You can draw these symbols on paper to include in bags, charms, candles, spells etc., they also are effectively worn on the person. Each individual symbol has its own best way for use. Also, most deities typically have some sort of representative symbol that could also be used if fitting. Many animals are considered symbolic and helpful as well.
Communication - It is sometimes reccomended to try and contact a spirit to find out its motives for following/haunting, to better appease and help the spirit to move on. I would only recommend personally attempting this with calm, non troublesome spirits, and I would avoid objects like pendulums or spirit boards. Instead, speak in a calm but firm voice, like you would a person who also needs help. Seeking the help of a sensitive or medium would also be most effective. If you simply want the spirit to leave, speak firmly and confidently to the spirit, as respectfully as possible, and tell them they need to leave. Explain that this is your space, and they are no longer welcomed. You can also research your home and surroundings to try and identify a specific person or name or incident that could be involved. When a spirit becomes violent and threatening, it is most likely best to get in contact with a professional who specializes in such events.
Taken from The Enclopedia of 5000 Spells -
*Basic Banishing Powder
Sprinkle on clothing, the ground, to enhance spells or other powders etc.
-rue-saint johns wort
Crumble all the ingredients, grind them into a powder, then burn on incense.
Garlic blossoms and angelica flowers tied with a blue ribbon.
*Bean Banishing Spell
Fill rattle with beans and shake to repel low-level spirits. Can also be incorporated in rituals.
*Botanical Spirit Banishing
The following plants, when kept living in or near a house, supposedly make a spirit feel unwelcome - juniper, corn, mugwort, saint johns wort, vervain, wormwood, and yarrow.
*Disperse Evil Incense (1 & 2)
-benzoin, frankincense, and juniper
-benzoin, patchouli, and sandlewood.
*Woodlands Banishing Spell
Burn acorns, mistletoe, and oak bark to repel undesired spiritual guests while murmuring your desire for them to leave.
These were just the simplest spells I picked that I thought would be affective. The book also has a section on exorcism spells but I recommend only seasoned experts attempt them.
Last but not Least - Make sure you are taking care of yourself and your home. Live a healthy lifestyle, eat regularly, get exercise, sleep on a steady cycle, address any medical concerns (physical and emotional), spend time with friends and family, make sure your space is clean and inviting and feels like a home. Let go of any toxic people or influences in your life. Try to diminish added stress in any way that you can. Enjoy relaxing activities. Tune up your own skills and talents. All of these things aid in your own personal power and defense against things latching on to you. Negativity of any kind is a breeding ground of attraction. Spirits LOVE to feed off of your own energy - don’t give them a reason to.
Sometimes it is also believed that displaying negative images throughout a house (skulls, death, gore etc) can also attract a spirit to stay. There’s also a lot of things involving displaying mirrors and the layout of furniture, but I’m not too particularly versed with that stuff.
Well, this is all I could think of right now to add to this list. I’m sure I’ll think of something else to add later and kick myself. But anyway - please always remember to seek real life help (not just me or anyone else on the internet) if things become bad or too far out of your control. Almost every state has their own paranormal team, but make sure to research them and weed out the hokey, amateur ones. Same goes for psychics and mediums. The best thing I think you can do is take control of your own space and your own life. I really hope this helps!!!
***Side note - I realized a lot of things I posted involve the use of fire in some way, so ALWAYS be cautious when burning herbs or using fire in spells. I personally keep a fire extinguisher in my room for this reason. Please please please be safe.
