Do You Pre-Treat Your SubStrate?

You could bake the wood at around 150ish for a while to kill off.mites that might be in the chips. It's really up to personal preference

The only problem with this is that during the baking process you scorch the pores in the wood. Since you are using cypress mulch I am assuming you have a problem with humidity. If the pores are scorched then it doesn't retain water as well. What I do is put the entire bag into the freezer for 3-4 days and let it sit inside a separate room from your reptiles for another day or two. this will ensure that all eggs, larvae, and adult mites are taken care of.
