No prob... they are nasty little buggers, that's for sure!
Generally speaking that piece isn't done for. You could blow them off with a turkey baster, thoroughly inspect for eggs (scape off if you find any), then dip, then place into QT. I believe what John was saying is that he had other coral in his current QT, that were likely pest free, so he didn't want to add this to it (nor would I).
If I did the above things and had a fallow QT available, I'd let it remain there for a month, and dip it once a week, thoroughly inspecting for other eggs or FWs every time.
