If there was a call at 2:00 a.m., they were probably swarming. There will be dead termites all over the floor in the morning for the actors to sweep up. They don't bite. The queen was looking for a new nest and took a bunch of termite lackeys with her. Don't move the actors. My termite (and other pests) company in Key West comes whenever I see termite dust on the floor. They inject stuff in the walls. The termites die or move for a while. I pay about $350 a year to Truly Nolan. I assume that you are renting the house from local owners. They should sign on to one of these companies. On the other hand, southern termites might be slower and lazier than other termites so do a little more research - but swarming yes -- otherwise they don't usually leave the walls. (at least that's been my experience).
