Yes, they go bad. You can tell because the bag gets hard

Does this mean that men who get hard are bad too?

If there are large (lemon - orange size) hard lumps in the bag, dump it. If
the lumps are small (pea - bean) and the rest is still powder, use it being
sure to crush the lumps.

It's a good idea to keep the stuff in the refrigerator to keep it dry,
but putting oranges, lemons and peas in the bag are downright stupid.

Around (central Florida) here an unopened bag is bad in a year or so. I
keep both opened and unopened bags in a garbage bag tied shut and even an
opened bag is good for a year.

The use of a garbage bag makes it easy to dispose it when it goes bad.
Smart moove!
