I was at my local pet store the other day and a person there told me that cypress mulch is the same thing as jungle earth, therefore I could get a ton more substrate from walmart then pay ten bucks for the jungle earth stuff at the pet store. Well I made the switch two days ago and I was just curious to know whether anyone else had done this and to make sure that it would be ok health wise for my snakes. My second question is that now that I have switched to the cypress mulch I have seen one or two of these little tiny flys in their housing, what are these, how do I get rid of them and do they pose a threat to the snake. Any advice would be appreciated.
