ProRep Spider Life 10 Litre ProRep Spider Life is part of the species-specific life series of substrates and has been created to meet the needs of spiders and scorpions originating from humid habitats, including burrowing species. It is a blend of ingredients that provide the ideal mix of structure and moisture retention whilst promoting natural digging and burrowing behaviour. Directions: Spread the substrate evenly over the bottom of the enclosure to a depth suitable for the species. For most species 1-2" (2.5-5cm) is adequate but burrowing species may require 2-4" (5-10cm) of substrate in order to construct their burrows correctly. Spot-clean regularly to remove soiled substrate and replace completely every 2-3 months or as needed. Keep the substrate evenly moist but avoid making it too wet.
