I'm going to try to get a bad tenant kicked off section 8
Why do you want to get her kicked off section 8?
She leaves dirty dishes around.
That is not a good enough reason for someone to lose their housing. Just tell her to clean up after herself peacefully.
She is so dirty she deserves to be kicked out.
Being dirty is not a reason for that. It is rude to try and get her out. Speak to her about her problem and how it can be fixed, instead of resorting to that.
