Push against the areas near where you see holes. You will probably find some soft spots and termites if still active.
It is just not worth the risk to bring it in the house. If you don't see anything, it probably isn't actively infested. I let my termite coverage lapse 1 year and this was a full brick home, but wood frame. My daughter noticed them when she removed a poster from her wall. They were eating through the caulk at the baseboard and about 6 feet up. We had people look at it and say yeah just patch it up, they didn't do any structural damage. Ha! I had the drywall removed. They ate everything. About 3 feet wide and up to about 6 feet the wood was just nuked by the termites. My current home is block with steel frame (still wood frame roof though). I've owned it for ~15 years. I never had termite coverage before. I sure as hell have it now.
