Leaf litter provides visual barriers and hiding spots for your animals. Especially good for tropical and temperate species of frogs, geckos, small snakes, lizards, and invertebrates. As the leaf litter breaks down it adds nutrients to the substrate as well as food for springtails and isopods which are all important parts of a naturalistic, bio-active terrarium. All of our leaf litter for sale is clean and is collected from chemical free areas!
