Hi there, pet lovers! 🐛
Are you looking for a unique and fascinating addition to your home? The Giant Millipede (Archispirostreptus gigas) might just be the perfect pet for you! These gentle, slow-moving arthropods are a joy to care for and observe, making them an excellent choice for both beginners and experienced invertebrate enthusiasts. Here’s why Giant Millipedes are such captivating companions:
Ease of Handling: 4/5
Giant Millipedes are among the most handleable invertebrates you can own. Their calm and docile nature makes them a great choice for those who want a low-stress pet that can be interacted with regularly. Unlike some other arthropods, Giant Millipedes are not prone to biting or aggressive behavior. They move slowly and deliberately, which makes them easy to manage even for first-time owners.
However, it’s important to handle them with care. Their exoskeletons are sturdy but not indestructible, and dropping them or applying too much pressure can cause injury. Always support their entire body when picking them up, and avoid handling them for extended periods, as they can become stressed if kept away from their humid environment for too long.
One thing to note is that Giant Millipedes can secrete a mild defensive fluid when they feel threatened. This fluid is harmless to humans but can cause minor skin irritation for some people, so it’s a good idea to wash your hands after handling them. Overall, their gentle nature and ease of handling make them a joy to interact with.

Care and Maintenance: 4/5
Giant Millipedes have relatively straightforward care requirements, but they do need a specific environment to thrive. They are tropical creatures, so maintaining proper humidity and temperature is essential. Aim for a humidity level of 70-80%, which can be achieved by misting their enclosure regularly and using a moisture-retaining substrate like coconut fiber or peat moss.
Temperature is another key factor. Giant Millipedes prefer a warm environment, with temperatures ranging from 72-78°F. A small heat mat or low-wattage bulb can help maintain this range, but be sure to monitor the temperature closely to avoid overheating.
Their diet is simple and inexpensive. Giant Millipedes are detritivores, meaning they feed on decaying plant matter. You can provide them with a variety of fruits, vegetables, and leaf litter. Some favorites include cucumber, zucchini, apple, and banana. Additionally, they need a source of calcium to support their exoskeleton, which can be provided through cuttlebone or calcium powder sprinkled on their food.
Cleaning their enclosure is relatively low-maintenance. Spot-clean any uneaten food or waste regularly, and replace the substrate every few months to prevent mold and bacteria buildup. With a little attention to detail, caring for a Giant Millipede is a rewarding and straightforward experience.
Health and Durability: 3/5
Giant Millipedes are hardy creatures when provided with the right conditions. They are not prone to many health issues as long as their environment is kept clean, humid, and warm. However, they can be sensitive to sudden changes in temperature or humidity, so consistency is key.
One common issue to watch for is dehydration. If the humidity in their enclosure drops too low, they may struggle to molt properly, which can lead to complications. Ensuring a consistently moist environment and providing a shallow water dish can help prevent this.
Molting is a natural process for Giant Millipedes, during which they shed their exoskeleton to grow. During this time, they may become less active and hide more often. It’s important to avoid handling them while they are molting, as their new exoskeleton will be soft and vulnerable.
With proper care, Giant Millipedes can live for several years, making them a long-term companion for those willing to invest the time and effort.

Availability: 2/5
Giant Millipedes are not as widely available as some other exotic pets, but they can still be found with a bit of effort. Many specialty pet stores and online invertebrate breeders offer Giant Millipedes for sale. They are often available in a variety of species, each with its own unique size and coloration.
However, it’s important to purchase from a reputable source to ensure you’re getting a healthy and ethically sourced millipede. Some species are protected due to overcollection in the wild, so always do your research and choose a responsible seller.
Initial Cost: 4/5
The cost of a Giant Millipede itself is relatively low, typically ranging from $20 to $50 depending on the species and size. However, setting up their enclosure can add to the initial expense. You’ll need a suitable tank or terrarium, a moisture-retaining substrate, a heat source, and decorations like hides and leaf litter.
While the initial setup might cost around $100 to $200, the ongoing costs are minimal. Their diet consists of inexpensive fruits and vegetables, and their enclosure only needs occasional substrate changes. Overall, Giant Millipedes are an affordable pet option for those interested in invertebrates.

Final Thoughts: 3.4/5
Giant Millipedes are a unique and fascinating pet that offers a rewarding experience for those willing to meet their care requirements. Their gentle nature, ease of handling, and low-maintenance diet make them an excellent choice for both beginners and experienced keepers. While they do require a specific environment to thrive, their care is straightforward once you’ve set up their enclosure properly.
