Chinese mantis care guide
Tenodera sinensis
Molting clearance decides the size: at least three body lengths of height so the mantis can hang upside down and pull free. A short enclosure is the single most common cause of a failed molt.
Arboreal — vertical height first
Chinese mantis enclosure size
Arboreal — vertical height first. An adult chinese mantis should live in at least 5" L × 5" W × 9" H; we build toward 6" L × 6" W × 12" H (0.5 × 0.5 × 1 ft, roughly 0.3 sq ft of floor and about a 2-gallon glass equivalent).
Rough ceiling (mesh or fabric) is mandatory — a smooth lid means the mantis falls mid-molt.
- Nymph L1–L3
- 4" L × 4" W × 6" H recommended · min 3" L × 3" W × 5" H
- Nymph L4–L6
- 6" L × 6" W × 10" H recommended · min 4" L × 4" W × 8" H
- Adult
- 6" L × 6" W × 12" H recommended · min 5" L × 5" W × 9" 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 60–70% ambient. Dampen one corner of the substrate every week or two and keep a water dish full — never soak the whole enclosure.
Substrate and depth
Coco fibre or paper towel. Depth: 0.5–1 in.
- Ventilation: Ventilated on the top and one side; humidity comes from a morning mist that dries out by evening.
Enclosure tips and furnishing
- Mesh or fabric ceiling to hang from
- Twigs and silk plants filling the upper half
- Light mist on the walls each morning for drinking
Build list
- Vertical mesh-top mantis enclosure — The mantis hangs from the ceiling to molt; mesh gives grip and ventilation at once.
- Fruit fly and blue-bottle feeders — Flies for nymphs, blue bottles and roaches for adults — mantids only take moving prey.
- 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.
Chinese mantis FAQ
How big should an adult Chinese mantis enclosure be?
At least 5" L × 5" W × 9" H, and we recommend building to 6" L × 6" W × 12" H — about 0.5 × 0.5 × 1 ft, or a 2-gallon glass equivalent. Arboreal — vertical height first.
What temperatures does a Chinese mantis 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.

Does a Chinese mantis 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 Chinese mantis need?

What substrate is best for a Chinese mantis?
Coco fibre or paper towel, at a depth of 0.5–1 in.
How big does a Chinese mantis enclosure need to be for a hatchling?
Nymph L1–L3: 4" L × 4" W × 6" H recommended, minimum 3" L × 3" W × 5" H. Scale up to the adult footprint as the animal grows.
How much ventilation does a Chinese mantis enclosure need?
Ventilated on the top and one side; humidity comes from a morning mist that dries out by evening.
