Learn a banishing and warding method that works well for you or try this:
Either way will work but you don’t have to take this, and shouldn’t as it isn’t safe nor healthy.
If you’ve been practicing a banishing ritual to the point you feel that you have it mastered and it still isn’t working, summon the above being. She can take care of it regardless of regular banishing failing you. Maybe your intent wasn’t clear with your normal practice or maybe you are so out of whack, that it’s rendered you somewhat unable to use it. I like some banishing methods better than others, but if my own intent is not strong enough or my will to do so, sometimes it doesn’t work for me, even when I use the one I’ve been using for a while. Sometimes you just have too much built up for one banishing to work.
Either way, if it’s truly not working for any reason, including ones I have yet to think of- the above servitor will take of the issue and establish strong wards that won’t let them just walk all over you or enter your space so that the problem doesn’t happen again, as this is at least the THIRD time you have posted something like this.
Three times in a few months is too many. You need to figure out how to take actions prevent this from happening. Twice in the space of less than two weeks, means something is not right.
If you are summoning things, you really should stop, until you can maintain operatorship and banish anything you attract and summon as this sounds like you are attracting parasites, if they are attaching to you and not real beings.
