Draw another set of pictures.. like a comic strip.. showing it that you’re sorry, that you’re leaving it to do its thing in peace and you wish for it to do so as well for you. In the drawing, show that you don’t intend to bother it and any drawings with it or its kind present, would not be shown to anyone. Push it under your room door for it to see your message in the form of drawings. Maybe it might leave you alone? Worth a try.
