Our live oak leaf litter is collected from 100% pesticide and herbicide free environments. Isopods should always have a constant source of leaf litter inside their enclosure. This allows them to consume the organic material over time, while offering shelter. Isopods will not only consume the leafs, but often prefer to hide underneath them. It looks great in a naturalistic vivarium as well. Our live oak leaves break down over time and will eventually be consumed by any isopods in the enclosure. Leaf litter plays a very important role in a naturalistic vivarium as well as any isopod enclosure. The leaf litter provides shelter, visual barriers, and hiding places for the inhabitants. Each live oak leaf also puts nutrients back into the environment, providing plants and microfauna with food needed to thrive! One gallon of leaf litter will cover approximately 1.5 square feet to the desired depth of 1 inch.
