Giant Burrowing Cockroaches (Macropanesthia rhinoceros) are Australia’s largest and heaviest cockroach species, known for their calm nature, impressive size and surprisingly long lifespan. Native to Queensland rainforests, they live underground in deep burrows and feed on leaf litter and decaying plant matter. Quiet, odourless and low-maintenance, they are popular with, families and invertebrate enthusiasts looking for a unique, fascinating and easy-to-care-for display animal.
Basic Information
The Giant Burrowing Cockroach (Macropanesthia rhinoceros), also known as the Rhinoceros Cockroach, is the world’s heaviest cockroach and a unique, long-lived Australian invertebrate. Native to Queensland rainforests, this species is terrestrial and fossorial, spending most of its time burrowing in soil and leaf litter. Adults can reach up to 8 cm in length and may live for 5–10 years. Despite their appearance, they are clean, quiet and slow-moving, making them excellent display animals for beginners, and invertebrate enthusiasts.
Essential Supplies
Secure Enclosure
A sturdy enclosure with a secure lid is required to prevent escape. Ventilation is important but should not allow excessive drying of the substrate. Plastic tubs or glass enclosures with mesh lids work well.
Substrate
A deep, moisture-retaining substrate is essential for burrowing. Use a mix of organic soil, coco fibre and leaf litter. The substrate should be at least 10–15 cm deep and kept slightly moist but not wet.
Leaf Litter & Bark
Provide eucalyptus or hardwood leaf litter and pieces of bark. These act as food, shelter and enrichment and help replicate the natural forest floor environment.
Hides
Although they burrow naturally, adding curved bark or hollow logs gives additional shelter and security.
Water Source
A shallow water dish with stones or sponge to prevent drowning should be provided. Regular misting also assists with hydration.
Cleaning & Maintenance Supplies
Spare substrate, paper towel and insect-safe cleaning tools are required to maintain hygiene without disturbing the enclosure excessively.
Housing
Giant Burrowing Cockroaches require floor space and deep substrate rather than height. A single adult can be housed comfortably in a medium-sized enclosure, while multiple individuals may be kept together if space and substrate depth are sufficient. The enclosure should be kept in a quiet, shaded area away from direct sunlight and temperature extremes.
Environment
This species thrives at temperatures between 18–26°C and does not require additional heating in most homes. Avoid temperatures above 30°C, as overheating can be fatal. Humidity should be moderate, achieved by lightly misting the substrate and leaf litter as needed. The enclosure should never become waterlogged. No UVB or specialised lighting is required; ambient room light following a natural day/night cycle is sufficient.
Diet & Feeding
Giant Burrowing Cockroaches are detritivores, feeding primarily on decaying organic matter. Offer a diet of eucalyptus leaves, hardwood leaf litter, rotting wood and occasional fresh vegetables such as carrot, pumpkin or leafy greens. Food should be pesticide-free. Replace fresh foods before they spoil to prevent mould. Supplements are not required when a natural, varied diet is provided.
Behaviour & Handling
These cockroaches are calm, slow-moving and non-aggressive. They may produce a hissing sound by rubbing body segments together when disturbed. Handling should be minimal and gentle, allowing the cockroach to walk onto hands rather than being picked up. Due to their burrowing nature, they are best appreciated as a display species rather than a hands-on pet.
Common Health Issues
Giant Burrowing Cockroaches are hardy, but improper conditions can lead to health problems. Regular observation of activity levels and burrowing behaviour is important.
Dehydration
Dehydration can occur if substrate dries out completely or water is unavailable. Signs include lethargy and reduced movement. Maintain lightly moist substrate and provide fresh water.
Mould-Related Issues
Excess moisture and poor ventilation may cause mould growth, which can be harmful if ingested. Remove mouldy food or substrate promptly and improve airflow.
Injury from Disturbance
Frequent digging or handling may cause stress or physical damage. Avoid unnecessary disturbance of burrows and limit handling.
Poor Moulting (Juveniles)
Juveniles may experience moulting issues if humidity is too low or substrate depth is insufficient. Ensure adequate moisture and deep substrate to support natural moulting behaviour.
Health, Hygiene & Safety
Spot-clean uneaten food and surface waste as needed. Full substrate changes should be done infrequently, as these cockroaches rely on established burrows—partial substrate replacement is preferred. Always wash hands before and after handling or enclosure maintenance. Avoid chemicals, aerosols or insecticides near the enclosure.
Record Keeping
Keeping basic records is recommended, especially for long-term care. Record enclosure maintenance, feeding additions, substrate changes and any unusual behaviour. Due to their long lifespan, records help track health and environmental stability over time.
Holiday Care
Giant Burrowing Cockroaches are low-maintenance and can be left for short periods if food and moisture levels are adequate. For longer absences, arrange for a carer to check moisture levels and replace food as needed. Written instructions are recommended.
Transportation
For transport, use a secure, ventilated container with damp substrate and leaf litter. Keep the container stable and avoid temperature extremes. Transport should be calm and brief.
Compatibility with Other Animals
This species should be housed alone or only with others of the same species. Do not house with predatory insects or animals. Keep enclosures away from pets such as birds, reptiles, cats or dogs.
