Just mind whatever bedding you buy if you get it from a gardening store. Make sure it's untreated as you don't know what they've used so best to bake it or treat it yourself with a reptile safe product. Baking it is a great idea as it gets rid of bug issues, can do no harm and often the cypress mulch is very damp anyways (at least the stuff I buy over here for the big boa is). I've yet to see any bugs in the aspen I buy but then you'd have a different supplier over there.
