American Giant Millipede
The American giant millipede is a large species native to a wide range of the eastern United States. Its brown body ringed with red bands along each segment gives it a striking look, paired with a calm, unhurried temperament. It moves slowly, rarely shows aggression, and simply curls up when startled. As a detritivore that feeds on leaf litter and decaying wood, it's a hardy, adaptable species that tolerates minor husbandry fluctuations well, making it a great choice for first-time millipede keepers. Many individuals live for years, rewarding owners with a long-term companion.

7 things to know before welcoming a American Giant Millipede
1Large but Gentle
Adults grow to about 8–10 cm, but they move slowly and show almost no aggression. When startled, they simply curl into a coil for protection, making them easy and calming to observe.
2Humidity Is Key
Since they favor moist forest-floor environments, the substrate should stay consistently slightly damp. Allowing it to dry out can stress the millipede, so regular misting is recommended.
3Provide Deep Substrate
They naturally burrow into the ground, so a deep layer of substrate helps them settle in comfortably. Moisture-retentive materials like leaf mold or coco fiber work well.
4A Decomposer's Diet
As decomposers, they favor leaf litter, decaying wood, and slightly overripe vegetables over fresh produce. Offering partially decomposed matter tends to suit their natural feeding habits best.
5Built for the Long Term
With a lifespan of roughly 7 to 10 years, this species is a long-term commitment rather than a short-lived pet. Plan for stable, consistent housing from the start.
6Handle Minimally
When disturbed, they may secrete a defensive fluid, so frequent bare-hand handling isn't recommended. It's best to mostly observe them and handle gently only when necessary.
7Best Kept Alone or in Groups Carefully
Their calm nature means communal housing is possible, but if this is your first millipede, starting with a single individual helps you learn its rhythms and care needs first.
