Our all natural Repta-Bark bedding makes for the most natural and rugged substrate for your pet, especially in high humidity tanks. This orchid bark is an excellent natural bedding for all high-humidity-loving reptiles. Bigger pieces mean less chance for ingestion and less dust. This 100% natural Repta-Bark Substrate is designed to absorb excessive moisture in your reptile's terrarium. The aesthetically pleasuring forest floor substrate functions as a waste absorber, and prevents fungal infections that your reptile may get in overly moist environments.
