Great job Schawee! I appreciate you taking this one on, the man was very happy with your work!
Its clearly evident by all the wax moth cocoons and ants that the person before you didn't remove any comb. Can't be certain when the ants showed up, possibly when the prior hive was dwindling.
This removal was not for your average joe.
Liz, we try to remove all brood comb the same day and generally most honey comb as well but on some difficult/time consuming removals you have no choice but to leave things well alone until the next day.
On some, the queen will hole up somewhere in a void with a bunch of bees and you have no choice but to wait things out which could mean going back the next day.
John, I've had larvae pop out of cells before, this occurs for the most part when bees aren't covering those comb sections.
