Freezing the food may extend its shelf life beyond the bb date but best to stick close to that.
I've never frozen substrate, there may be a slight risk of bugs but it's just not practical, I do freeze things like hay, dried flowers, leaves & moss.
I don't know what paper wool is.
Bugs & moths aren't only found in pet foods, they can be found in human foods too, firts ones I found were in a bag of flour! The main risk with ham food is that you won't see any eggs until they hatch out in the cage.
