The best food for millipedes is a detritus-based diet: leaf litter, well-rotted wood and mature substrate. Fresh fruit and vegetables can be useful occasional supplements, but they should not replace the natural food base that millipedes graze on long term.
For a broader overview, see our What Do Millipedes Eat? Complete Feeding Guide and the wider Millipede Feeding Guides.
What should millipedes eat?
Millipedes are detritivores, so the food they use best is decaying plant material rather than crisp, fresh produce. A good enclosure should be built around the same materials they would graze on naturally: leaf litter, rotting wood and an organic substrate that can break down over time.
Leaf litter should be plentiful and kept available all the time. It is a staple part of the diet, not just decoration. As leaves soften, age and become colonised by microbes, they become more useful to millipedes. For a closer look at the role of leaf litter, see Leaf Litter vs Supplemental Food for Millipedes.
Well-rotted wood is another key staple. The important point is that it must already be well broken down; fresh, hard wood is not the same thing. Good rot wood is soft, crumbly and partway through decomposition. For more detail, see Rot Wood as Food for Millipedes.
Mature substrate also matters because it gives millipedes a living food base to graze through. In a healthy enclosure, feeding does not happen only on a visible food item. Much of it takes place under leaf litter, bark and the upper layers of substrate.
Fresh vegetables and fruit can be offered as supplements, but only in small amounts and not as the main diet. They are best treated as occasional extras for variety and additional moisture, while the detritus base remains the foundation of feeding.
How much and how often
Keep the natural food base available at all times. Leaf litter and well-rotted wood should not be rationed out as if they were occasional treats. Supplementary foods, on the other hand, work best in small portions and at a sensible interval, adjusted to what the enclosure actually uses.
There is no fixed schedule that suits every setup. Species, colony size, temperature and how mature the enclosure is all affect how quickly food is taken. A practical approach is to offer just enough fresh food for the colony to use without leaving excess to sour or mould.
If you want timing advice for different setups, our guide How Often Should You Feed Millipedes? goes into more practical detail.
What to watch
Feeding is easiest to judge by the enclosure as a whole, not by whether millipedes rush to a fresh item.
Good signs include leaf litter gradually thinning, rot wood being steadily grazed, and supplements being taken in moderation rather than ignored completely or left to rot.
Signs you may need more natural material include leaf litter becoming scarce, rot wood disappearing without being replaced, or a thin-looking enclosure with very little detritus left to browse.
Signs you may be overfeeding supplements include mouldy leftovers, sour-smelling food, sticky waste around feeding areas or food sitting too long without being used.
Millipedes often feed under cover, so a quiet surface does not always mean they are not eating. If the detritus base is being reduced steadily and the enclosure stays clean and active, the feeding routine is usually on track.
