I use wards. My ward to hold all energy inside my room is an iron horseshoe.
I got a set of 4 used ones off ebay. (you want used, horses are also magickally protective and there’s a bit of horse in the shoe).
My horseshoes are set above the lintel of every exit in my house, which are the front door the back door, the chimney, and… the door to my craft room.
I also have another layer of wards around the whole house and garden so the temple room is still warded from out side.
And finally I will banish an smudge the whole house of unwanted energy whether its sentient or not.
