“Substrate” is another word for corn snake bedding — the material that you use to cover the floor of your pet’s enclosure.
Using the right substrate in your corn snake’s terrarium can help regulate humidity and promote good health. Using the wrong substrate can be unhygienic and can even kill your snake in severe cases.
For best results, substrate should be layered at least 3″ thick to facilitate natural burrowing behavior and help maintain healthy humidity levels. Remove waste and contaminated substrate immediately, and replace all substrate at least once every 3-4 months.
