What's the best product to use on hardwood floors that have been recently refinished and stained? We have a mix of new red oak & old red oak, all stained the same...but the old oak has its share of crevices and cracks, and various sizes of gaps between individual boards. Those crevices & cracks I've heard are the kinds of places where fleas like to hide & mate. Since we're already having a bad flea season in Georgia, I want to take an aggressive approach to keeping my hardwood floors clean *and* hopefully finding a way to prevent fleas from making homes in the crevices of our floors.

Somebody please help! I'll do anything to keep on top of this, as it is going to be a *long* hot summer here. Thanks in advance!
