For those of you who have read my thread titled "Something is living in the substrate..." I have fixed the problem. Now I need another kind, and from what I've experienced I will only buy heat-treated substrates (I understand my case was rare but I'm not taking any chances so I'm not buying Exo-Terra Jungle Earth anymore). What kind of heat-treated substrate (preferably one that's good for a Hognose snake) would you recommend?
