Pep Cups

Pep Cups — Natural Hides & Enrichment for Isopods, Millipedes & Bioactive Enclosures

Pep cups are a fantastic natural bioactive terrarium supply for terrariums and isopods. Measuring 20–40mm each, their unique shape creates a snug, sheltered microhabitat that mimics the natural nooks and crevices invertebrates seek out in the wild — helping to reduce stress, support safe moulting, and encourage the most natural behaviours in your colony.

Why Isopods & Millipedes Love Pep Cups

• Safe moulting hides — The enclosed, sheltered shape provides isopods and millipedes with a secure retreat to moult safely, away from light and disturbance.
• Reduces stress — Having access to adequate hides is essential for invertebrate wellbeing. Pep cups give your colony the security they need to thrive.
• Natural food source — As pep cups slowly soften and break down, isopods and millipedes will graze on the organic matter and biofilm that develop on the surface.
• Humidity retention — Their natural material retains moisture well, helping to create and maintain the localised humid spots that isopods and millipedes actively seek out.
• Ideal size for most species — At 20–40mm, pep cups are perfectly sized for a wide range of isopod and millipede species, from juveniles to large adults.
• Beautiful aesthetics — Their organic shape adds a charming, naturalistic feel to any vivarium.

Benefits in Bioactive Terrariums

• Microhabitat creation — Pep cups create distinct sheltered zones within the enclosure — perfect for clean-up crews and healthy ecosystems.
• Supports the decomposition cycle — As pep cups break down over time, they contribute organic matter to the substrate, feeding beneficial bacteria, fungi, and microfauna.
• Springtail habitat — The moist, sheltered interior is an ideal microhabitat for springtail colonies, helping them establish and thrive within the enclosure.

A high-quality organic material for bioactive setups UK-wide, suitable for reptiles, amphibians, and microfauna habitats, as well as all isopod and millipede species including Porcellio scaber, Armadillidium vulgare, Cubaris sp., Narceus sp., and many more.

Disclaimer: While every effort is taken to ensure our products are safe for use, we strongly recommend cleaning and sterilising them yourself before introducing them to your enclosure.
