Dairy Cow Woodlice Pre-pack | Isopods for Bioactive Terrariums

The Dairy Cow Woodlice Pre-pack contains Porcellio laevis isopods — one of the most versatile invertebrates in the reptile hobby. Whether you're building a bioactive vivarium that runs itself or sourcing a calcium-rich livefood for reptiles and amphibians, these isopods earn their place in any serious keeper's setup.

Bioactive Clean-Up Crew

Dairy cow isopods are well established as terrarium custodians. They break down waste, decaying plant matter, and uneaten food, helping maintain a functioning bioactive substrate. Given the right conditions, they will breed readily within the enclosure and sustain a self-replenishing colony.

Livefood Use

Adults reach up to 20mm in length and carry a naturally high calcium content thanks to their calcareous exoskeleton — making them a nutritionally useful feeder insect without the need for additional dusting. For feeding, offer them in a smooth-sided dish to prevent escape, in the same way you would present mealworms or calci-worms.

Habitat Requirements

To become established in the terrarium, dairy cow isopods need a consistently damp, humid microclimate. In practice, this means they spend most of their time sheltering under rocks, branches, or within the substrate — exactly the behaviour you want from an efficient clean-up crew working through the enclosure.

Packaging and Ventilation

Your isopods arrive in a perforated plastic container, designed to provide adequate airflow while minimising the risk of escape during transit and storage.

Ongoing Care

Keep your isopods in good condition by supplementing their diet with fruit, vegetables, or a quality insect food. Consistent feeding supports colony health whether you're maintaining a bioactive setup or holding them as a livefood supply.

A genuinely dual-purpose invertebrate, the Dairy Cow Woodlice Pre-pack is a practical addition for keepers running bioactive builds or looking for a calcium-rich feeder with real nutritional credentials.
