Almost all termite swarms this time of year (April - May) are subterranean termites. The insulation in the walls had nothing to do with this, as subterranean termites are ground dwellers and infest from below. They travel in mud shelter tubes from the soil to the home. They eat wood, paper backing on sheetrock, trim, cabinets, etc.
The swarmer are actually kings and queens that are in the reproductive stage. They swarm and leave their nest this time of year to start new colonies. The swarmers that you saw indoors will die and not be of any concern.
Swarmers that are able to make it outdoors, pair up with a mate, and begin a new colony can take many years to be of concern.
The major concern right now is that you have a very real termite infestation and it needs to be treated.
What I would recommend immediately is to use Termidor Foam and inject the walls near the baseboards with it. Make a small hole the size of a nail in between each stud along the entire wall and inject about 10 seconds of foam in each cavity.
Then you can decide if you want to do a complete perimeter Termidor treatment with Termidor SC or if you want to use a bait system such as Hex Pro Termite Bait.
