I live in Southern California where it's impossible to buy cypress mulch so I'm having some family from back east to ship me some huge bags from the local garden stores or walmart and I was wondering if I need to treat it in some way before using it with my snakes.

All the stuff I've bought before for the snakes have come from reputable reptile shops and were made specifically for reptiles so I didnt ever have to worry about this before, any opinions?
