❄️ Clean & Safe – Frozen Before Shipping

All substrate is frozen prior to shipment to eliminate pests and unwanted hitchhikers. Freezing preserves beneficial bacteria and microbial life far better than heat‑treating, ensuring your substrate arrives nutrient‑rich and ready to use.

🪵 Instructions for Use

• Provide 2–3 inches of substrate for most isopod species; burrowing species may prefer deeper layers
• Springtails thrive with 1–2 inches
• Bags arrive with natural moisture retention; for arid species, allow one side of the enclosure to dry to create a humidity gradient
• Reseal unused substrate to prevent pests from entering the bag
