The worst time of year for mold is late summer and early fall, when humidity hangs heavy and autumn rains keep things damp. I've noticed it's especially bad after a few days of steady drizzle, when the basement starts smelling musty and dark corners in the bathroom get those little black spots. It's that sticky, damp season where nothing dries out properly, and you have to run the dehumidifier constantly to keep the spores from taking over.
