Nuptial flights need perfect conditions to take place, its a good sign that you are seeing Alates (winged queens/males), keep your eyes peeled! they will fly soon! it may be tomrow, it may be in a few weeks.
Best bet is keep an eye on the weather reports, a shower of rain during the night or in the morning, and nice hot weather in the afternoon/evening is perfect for nuptial flights.
Of course not all ants fly during the day, but the fact you saw them around the nest during the day is a good sign they are a species that do, keep checking, around the same time. Its likly that the workers where pulling the alates back into the nest, because it wasnt the right time of them to fly.
Dont bother collecting a nest, unless you are experienced enough to know whether you have a fertile queen in the colony, it will probly be a waste of time, and they will die
