Not sure if this is the right section to pop this in but here goes =0)

You know those annoying little packets that they put in (mostly) shoe boxes to prevent problems with dampness?
would it be beneficial/feesable to put them into caches to prevent problems with damp?
the only problem I can think of would be if a creature were to get into the box it may eat it =0(
Anyway just an idea that popped into my head the other day let me know what you think =0)
