I doubt you would see any outside as yet... I just checked the temp at my daughter's house - she has this fancy thermostat system I can read over the Internet, and, as we speak, it's 33 degrees up there. Not CA weather, for sure.
So it's POSSIBLE you have a nest inside. Or it might be actually on the "outside" but close enough that it has avenues into the inside. Regardless, I don't expect that you have a BIG problem or I suspect you would have been having it all along.
Couple of questions... Is your basement "unfinished," and does it have insulation on the ceiling? If so, it might be easy to lift that insulation up so you can see underneath - in the areas where plumbing pipes are. You might have a small leak, or even sweating pipes where the ants might have access to moisture - and they don't need much. I have seen a small CA nest of less than a hundred or so individuals, and depending on where they are, you could see just about all of them on almost any day. Rare, but entirely possible. The inverse is also true, you could have thousands of CA's and NEVER see them! So what you see can mean very little, so best to not panic.
Unless a nest is big, you probably won't see "sawdust" or frass either. Discovering is as much luck as skill. Or rather, luck COMBINED with skill...
Resist the temptation to go whole-hog with some kind of insecticides(s), our vacuum is your best pal in most instances. Insecticides will kill some, but tend to scatter the rest, and that's NOT good!
If you don't discover a nest, your best treatment, if it keeps up and you need it, will be to the outside, but not until all danger of freezing weather has ceased.
So gulp down any panic you or the wife has, for the moment, an keep on investigating.
