My house looks just like the ones that don’t have termites.

Termites have no capacity for 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 the water they need so that they can eat.

The best thing you can do is to get a professional inspection report done and read the report carefully. Next best is to keep reading and try and work it out for yourself. What has changed? In what subtle ways is my house differently exposed? Did anything make it easy for them? How are they getting in? Why is water available? If you can answer these, you’re most of the way to selecting a solution.
