How many frames is it on? If it is just that one I would take it out and have a bee inspector look at it. The bees can clean up small areas of a few cells, but it looks like something is pretty established on that frame. For double sure pull any frames if the goo sticks to a toothpick you have put in and spun. Like the man said, if it ropes out ,Then you may need a trip to the burn barrel.
