I guess the most important thing to have on hand would be a good shop-vac - one that works well.
What you MAY experience, but not always, would be your ants. Should you discover live ants, the vacuum would be your first effort - get those suckers OUT of there! Do a good job. And they may trickle out of there for hours, or even days. If, after about 3 days or so, they have stopped, they are (probably) all over with.
At that point, hopefully, and without going any further, you can often see the problem and also what's happening to cause this. FIX IT!
As far as chemical treatments are concerned, FIXING the problem is enough. But I understand anybody wanting to do "something more," necessary or not!
In that regard, a dust would be better. Dust will "go around corners" - liquids can easily be foiled by a couple of corners so it may not reach your intended target.
What kind? Depends on what's available where you are. The really effective dusts are not available anymore, so my choice, especially if it might get wet again, would probably be Delta dust. Or possibly a combination of DE and pyrethrum - there are many brands, look for the highest concentration of pyrethrum - 1% would be great. A bulb duster would be the best application tool.
BTW, you never need "GOBS" of dust - in fact, that will hinder the effectiveness of your treatment. For example, would you want to slog through many inches of snow, or tread easily over a light dusting? Got it? An 'old exterminator' from my youth, told me that "if you can SEE it, it's too much..."
And like just about everything else, 'old' exterminators are usually better than 'new' exterminators!
