Definitely wait it out. The vet isn't going to help you. My longest was 9 month for one of my girls. She usually fasts during winter and starts eating again in the spring.

As Deborah already mentioned, make sure you double check the husbandry and make sure the BP's terrarium is in a low traffic area.

Additionally, try to feed during evenings or at night. They're nocturnal creatures and respond better to feeding at night. Once the BP strikes (i'm assuming you're feeding ft) give them their privacy.
