I have seen all of the Alien movies as well as the Prometheus series. What do the drone or worker xenomorphs do once the host supply is depleted? Does the queen keep on laying more eggs, or does she know when "enough is enough"?

I think the implication is that if they run completely out of viable hosts in the reachable vicinity, they go into indefinite hibernation until they're woken up by the next bunch of hapless explorers.
