Well, I don't know about the "several weeks" thing, if I bait for ants, I tell people that it will take AT LEAST a few days to take effect, and before that, they're going to see even MORE ants, they'll be coming to get the bait and it will seem that it's not working. Actually, that's the way it works. But I never had it take "several weeks."
There again, it depends on the bait I use, but I don't see it taking that long. But since I don't know the bait used, and the chemical they used on the outside, I can't be absolutely sure.
Frankly, in exterminating, and since this is an expertise and not an exact science, I think the ethical thing to do is to use the cheapest and most efficient method. I would have started out with a perimeter spray with Termidor and told you to wait a week or so, to gauge the effects on the ants. Then, if you still had problems, further treatment might be called for. In many cases, the perimeter spray is sufficient, enough ants (inside and outside) will have mutual contact so as to spread the effect to the ants inside, so that might be all you need. In which case, all you pay for is the perimeter, saving you money and me time. I don't think I have ever baited inside at the same time as I do a perimeter spray with Termidor. That sounds like an add-on project that isn't necessary until it's necessary!
Exterminators are enured to multiple treatments,they want the extra money, regardless of whether it's needed or not. I don't ever think this is advisable, exterminators should use the LEAST amount of treatment as they can - at least in my book.
As far as the new location, it depends,,, And since they know what they used, they could (should) answer that better than I.
Hope I answered your question well enough.
