Submitted by – Diane, Glenelg, MD
Answer:
If they remain sealed in the package—and if they are not exposed to extremes of heat (oh, say, about 90°F and up)—they should last for four years, possibly longer. They start breaking down pretty fast once they are exposed to moisture and air, and kind of fast when exposed to heat. —Buck
