I see houses that are tented to treat for Termites. In the south they have a different kind of Termites, Drywood Termites, that are treated by tenting since they actually live in the house. Here in the Northeast we have Eastern Subterranean Termites. Since they live underground, tenting would have no effect on them. We treat our Termite in other ways including Chemical and Bait.
Termites drop their winds to mate and then try to return to the ground.
If you miss the swarm itself, you will find lots and lots of wings on a windowsill or near another heat or light source. The wings are the size and shape of rice. They are white-opaque and not visible reined. Ants do not usually drop their wings. See comparison Lastly Termite wings are all the same length while ants have long and short wings.
