Pep Cups

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

Pep cups are a fantastic natural hide for isopod and millipede enclosures. 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 of pep cups provides isopods and millipedes with a secure retreat to moult safely, away from light and disturbance — one of the most critical needs of any invertebrate keeper.
• Reduces stress — Having access to adequate hides is essential for invertebrate wellbeing. Pep cups give your colony the security they need to thrive, reducing stress-related losses.
• 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, supplementing their diet naturally.
• 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, complementing leaf litter, cork bark, and other natural décor.

Benefits in Bioactive Terrariums

• Microhabitat creation — Pep cups create distinct sheltered zones within the enclosure — humid, dark retreats that different species will actively seek out and utilise throughout the day.
• 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 of a pep cup is an ideal microhabitat for springtail colonies, helping them establish and thrive within the enclosure.
• Safe for reptiles & amphibians — 100% natural and untreated, pep cups are safe for use in enclosures housing reptiles, amphibians, and invertebrates.
• Easy to place & rearrange — Simply position anywhere in the enclosure and let your invertebrates do the rest. Available individually or in a pack of 5 for a fully furnished setup.

Suitable for all isopod and millipede species including Porcellio scaber, Armadillidium vulgare, Cubaris sp., Narceus sp., and many more. An excellent addition to tropical, temperate, and arid bioactive setups.
