@Greene,
That one I can't answer 100%, I let my chemical license lapse years ago, I only sparingly use glyphosate on a regular basis. I do know treatment for termites around a foundation is typically a soil treatment. But they drive it in deep, I watched the Big T folks treat my place. I would think what you replaced for bedding plants? I mean, you didn't use an excavator and dig the foundation? I think it would depend on the exact chemical and method of delivery, I used a spray years ago for a client that would have certainly been altered, if not negated by extensive soil removal but re-treatment wouldn't be a huge issue. Cost would depend on the applicator/salesman. The smell? I ditched my paper mask and went and got a respirator mask, I was afraid that insecticide ( termiticide is correct) was going kill everything it touched including myself. (it didn't). Maybe $100 for 2 gallons at the time and could've treated 2 houses (and out buildings). Primarily a topical spray, IIRC we did dig at the base of the foundation.
If that was the type treatment the previous owners had used (pretty much what I receive now) It's possible that you removed enough treatment to render it moot. Simple enough to re-apply and not terribly expensive. If you sold the house and the new owners ended up with termites it's well beyond your control. The house I have was clearly treated and the treatment either failed or hadn't had good follow-up. The only reason I pay for any such service now is due to replacing beams to hold the house up. The house will outlive me, bugs or not.
I'll consult my bug guy. Very conservative, low-key sort. I never get the impression that he considers his work an absolute necessity and I relate to that more than a scare tactic. Once my "warranty" period from Big T died they've been relentless for sales. I don't do business that way, I don't do business with folks who do their business that way. Guess that's why I didn't renew my health insurance, LOL.
But again I will consult my bug guy. My piques my curiosity. If every homeowner in America needs treatment and follow-up I could be rich and far from famous. I hate those moments of greed!
