According to some other people, and myself it seems at least in Northern New Jersey, there was a mass amount of Camponotus Pennsylvanicus nuptial flights, I'm assuming environmental queue's clicked. Look out for camponotus queens. An unorthodox method to catching queens, that has been working successfully for me is lifting up loose bark on fallen trees, or digging around a couple cm's deep into rotted logs, I have found 4 queens in their founding stages, it is usually fairly easy to capture the queen if she has her eggs already as she will be sitting around passively, the tricky part is getting the eggs/brood safely into the container/test tube setup, or if she has her first set of workers. But this has worked fairly well for me so wanted to suggest it. Good Luck.
