LOL, sorry to tell ya but we cut walls open to see what's going on in there. We have a locator with a camera to go underground and see if plant roots have invaded a sewer but that gear is expensive and IKT it would work for you.
I think you can use a thermal imaging camera for stuff that's alive. Ick. lol
I know you can see rodents with this, I'm not sure if it works for termites but it might.
Yeah, we're the delivers of bad news I'm afraid. Oh, so sorry you just had that new wall done, but we're going to have to cut that bitch open and see where this leak is coming from.

It's even worse when we have to jackhammer up a fresh new floor. We try to make the closest guess so that we don't have to damage too much.
