ProRep Spider Life Substrate

ProRep Spider Life Substrate is a species-specific substrate blend developed for spiders and scorpions from humid environments, including burrowing species. It supports natural digging behaviour while maintaining the moisture levels these animals depend on — available in a range of sizes to suit enclosures of different scale.

What It's Designed For

This substrate is part of ProRep's species-specific Life range, formulated specifically around the requirements of humidity-dependent spiders and scorpions. Whether you're keeping arboreal species that simply need a stable, moist base or obligate burrowers that need real structural depth, Spider Life is built with those needs in mind.

Blend and Performance

The mix balances structure and moisture retention in a single substrate. It holds its form well enough for burrowing species to construct and maintain tunnels, while staying moist without becoming waterlogged. This combination is what separates a purpose-built spider substrate from a general-purpose soil mix.

How to Use It

• Spread evenly across the enclosure floor at a depth appropriate to the species
• Most species are well served by 2.5–5cm (1–2 inches) of substrate depth
• Obligate burrowers require greater depth — typically 5–10cm (2–4 inches) — to construct burrows correctly
• Spot-clean regularly to remove soiled areas
• Replace the substrate completely every 2–3 months, or sooner if needed
• Keep the substrate evenly moist throughout — avoid saturating it

Choosing the Right Size

Spider Life is available in several pack sizes, from smaller quantities suited to compact setups through to larger volumes for bigger enclosures or keepers maintaining multiple animals. Select the size that matches your enclosure dimensions and required substrate depth from the options on this page.

For keepers who take their invertebrate husbandry seriously, having the right substrate in place is one of the most straightforward improvements you can make to an enclosure. ProRep Spider Life removes the guesswork from that decision.
