You say the puppy is getting hyper before it bites. I would put it in it's crate or behind a babygate at that stage, before it escalates. Leave it to calm down or have a nap before you let it free. Don't be angry, just be calm and in control. Give it a chew or a treat ball so it becomes a positive experience for the puppy.
I brought my puppy home at 7 weeks, feed Burns mini bites, and there's been no problem with biting, just a bit of finger-sucking in the first few days when she was wanting her mum.
