Hey Pam - We have termites too, but the nest was under some garages across the road. They xmen got the whole nest out, filled the land, muked the surrounding. Took FOREVER to clean up dead bodies that cropped up everywhere. But no other damage. Like LL said, the spectrum of termite impact is huge.
Keeping my fingers crossed yours is a minor case. Slowly.
ps. lots of happy people on this island today, England beat Switzerland 3-0
