I have a new home and the stupid builder didn't tell us he wasn't putting in a 'garbage disposal'! With granite countertops, we're kind of stuck. We have a drain on the sink hole, so big pieces of food don't get stuck down the drain. Little tiny flies have been appearing right on the drain- its really gross. I poured bleach on the drain and it seemed to take care of it for a few days. ugh, they're really gross!
