Bumblebee millipede care guide
Anadenobolus monilicornis
The substrate is both home and diet: composting hardwood leaf litter and rotten wood over deep soil. Get the substrate right and the rest of the care is water and patience.
Fossorial — deep substrate for burrowing
Bumblebee millipede enclosure size
Fossorial — deep substrate for burrowing. An adult bumblebee millipede should live in at least 8" L × 8" W × 10" H; we build toward 8" L × 8" W × 12" H (0.7 × 0.7 × 1 ft, roughly 0.4 sq ft of floor and about a 3-gallon glass equivalent).
- Spiderling / sling
- 8" L × 6" W × 8" H recommended · min 6" L × 4" W × 6" H
- Juvenile
- 12" L × 8" W × 10" H recommended · min 10" L × 8" W × 8" H
- Adult
- 8" L × 8" W × 12" H recommended · min 8" L × 8" W × 10" H
Temperature and heating
Heat the room, not the enclosure. If the room drops below 68 °F use a thermostatted space heater or a heat mat on the outside of a side wall (never under the substrate) — heat mats under a burrow cook the animal.
- Basking / warm surface
- None — no basking site, no heat lamp
- Warm side (ambient)
- 72–80 °F ambient room temperature
- Cool side (ambient)
- 70–75 °F ambient room temperature
- Night
- Room temperature; a 5–8 °F night drop is fine
Lighting and UVB
UVB: None — invertebrates need no UVB and bright light stresses them. Run lights on a Ambient room light on a normal day/night cycle; keep the enclosure out of direct sun photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target 75–85% ambient. Keep the substrate evenly moist (damp, not waterlogged), overflow the water dish and mist a wall rather than the animal.
Substrate and depth
Topsoil, coco fibre, crushed hardwood leaf litter and rotten wood, plus a calcium source. Depth: 6–10 in — they spend most of their life buried.
- Ventilation: Small vents only. These species need a closed, humid, composting environment — springtails in the bin keep mold in check.
Enclosure tips and furnishing
- Thick hardwood leaf litter layer
- Rotten wood chunks
- Cuttlebone or crushed oyster shell for calcium
- Shallow water dish or a heavy mist twice weekly
Build list
- Deep opaque bin or terrarium — Depth beats footprint; opaque sides make them surface more often.
- Hardwood leaf litter and flake soil — This is the actual diet — vegetables are a supplement, not the food.
- Digital thermometer / hygrometer — Inverts are kept at room temperature — you need to know what the room actually does, not guess.
- Long feeding tongs and a catch cup — Every interaction — feeding, water top-ups, rehousing — should happen without your hand near the animal.
Bumblebee millipede FAQ
How big should an adult Bumblebee millipede enclosure be?
At least 8" L × 8" W × 10" H, and we recommend building to 8" L × 8" W × 12" H — about 0.7 × 0.7 × 1 ft, or a 3-gallon glass equivalent. Fossorial — deep substrate for burrowing.
What temperatures does a Bumblebee millipede need?
Basking or warm surface None — no basking site, no heat lamp, warm side 72–80 °F ambient room temperature, cool side 70–75 °F ambient room temperature, night Room temperature; a 5–8 °F night drop is fine. Heat the room, not the enclosure. If the room drops below 68 °F use a thermostatted space heater or a heat mat on the outside of a side wall (never under the substrate) — heat mats under a burrow cook the animal.
Does a Bumblebee millipede need UVB?
None — invertebrates need no UVB and bright light stresses them. Photoperiod: Ambient room light on a normal day/night cycle; keep the enclosure out of direct sun.
What humidity does a Bumblebee millipede need?
75–85% ambient. Keep the substrate evenly moist (damp, not waterlogged), overflow the water dish and mist a wall rather than the animal.
What substrate is best for a Bumblebee millipede?
Topsoil, coco fibre, crushed hardwood leaf litter and rotten wood, plus a calcium source, at a depth of 6–10 in — they spend most of their life buried.
How big does a Bumblebee millipede enclosure need to be for a hatchling?
Spiderling / sling: 8" L × 6" W × 8" H recommended, minimum 6" L × 4" W × 6" H. Scale up to the adult footprint as the animal grows.
How much ventilation does a Bumblebee millipede enclosure need?
Small vents only. These species need a closed, humid, composting environment — springtails in the bin keep mold in check.
