Termites have no malice, so it is definitely nothing personal.  Their needs are simple. Food and shelter are almost always freely available for them in what we build. Water is the big issue and often we can build termites out by making it harder for them to get water so they can eat.

The best thing you can do is to et a professional inspection report done and read it carefully.  Next best is to keep reading and try and work it out for yourself.  What has changed?  Did anything make it easy for them? How are tehy getting in?  Why is water available?  If you can answer these, you're most of the way to selecting a solution.
