Here are some suggestions to help you prevent from pulling your hair out.
Isolate the student who is disrupting your class to an area of your classroom where no one sits. If you have to, move the students from the rows that surround the student and give him no one to talk to and no one to bother. If you have a full class, this suggestion may not work. If you have a table against a wall, move the student to that particular table so that the student is all alone and has no one to disrupt or bother.
Isolation and or alienation can work wonders and can increase the attentiveness of your class and eliminate those unnecessary disruptions.
