Could I legally void my lease in the state of North Carolina?

Nothing mentioned would allow the breaking of the lease, it is just part of community living in an apartment. If the loud noise is after 10 pm on week days or 12midnight on weekends you can call the police and they will respond. Spraying for bugs is normally done on a quarterly basis and if you have them in the apartment it is the renters responsibility to spray just like people in houses have to do. You could try to go to small claims court but you will most likely lose. The judges in real small claims court are not as funny or accommodating as Judge Judy.
