ProRep Spider Life is part of the species-specific life series of substrates andhas been created to meet the needs of spiders and scorpions originating fromhumid habitats, including burrowing species. It is a blend of ingredients thatprovide the ideal mix of structure and moisture retention whilst promotingnatural digging and burrowing behaviour.Directions:Spread the substrate evenly over the bottom of the enclosure to a depth suitable for thespecies. For most species 1-2″ (2.5-5cm) is adequate but burrowing species may require2-4″ (5-10cm) of substrate in order to construct their burrows correctly. Spot-cleanregularly to remove soiled substrate and replace completely every 2-3 months or asneeded. Keep the substrate evenly moist but avoid making it too wet
