You may be fine, but keep an eye on things. I had a hive swarm and I thought they were still doing ok. The queen must have died, the bees died out and the wax moths went to work. I can only check on the hives over the weekend, and from 1 week to the next, things got much worse. I shook out the last few bee's, cleaned up the wax moth webs and froze the frames.
