Madagascar Hissing Cockroach Enclosure Setup: Humidity, Substrate, and Keeping Them From Climbing Out
On This Page▾
This is one of the simpler enclosures on this entire site to set up correctly, with one specific detail that matters more than anything else: keeping them from climbing out.
Enclosure Size
A 5-gallon tank works as a minimum for a single animal or a small group. A 10-20+ gallon tank or plastic tub suits a larger colony better, floor space matters more here than height for this ground-dwelling species.
Temperature
75 to 85°F for general pet-keeping, room temperature above about 70°F is genuinely fine if you're not actively trying to breed them. Breeding specifically gets triggered around 85 to 95°F, worth knowing if you want to avoid an accidental population boom, or if you're deliberately trying to encourage one. A thermostat-controlled heat mat on one side of the enclosure creates a useful gradient if you do want warmer conditions.
Humidity
60 to 70%, maintained through daily misting and a substrate that holds moisture well. A simple humidity chamber, a small container with a damp sponge inside the main enclosure, works well too, a technique used by professional insect-keeping programs.
Substrate
Coconut fiber, peat moss, or orchid bark, 2 to 3 inches deep, supports this species' semi-burrowing habits well. Provide egg-crate stacks or cork bark as hides, they'll use these constantly.
Lighting
None needed. This species is nocturnal and photophobic, genuinely prefers darkness, and doesn't require any special lighting setup at all.
The Non-Obvious Requirement: A Petroleum Jelly Barrier
This is the detail that matters most for a successful setup. Madagascar hissing cockroaches are excellent climbers, capable of scaling smooth glass with ease. Smear a band of plain petroleum jelly around the top 2 to 3 inches of the enclosure interior, combined with a secure, tight-fitting lid, and escapes become a non-issue. Skip this step, and you'll likely find roaches outside the enclosure sooner or later.
Their sticky foot pads and leg hooks, the same grip that makes gentle handling important, are exactly what lets them scale smooth glass with ease. A secure lid alone isn't enough for this species, which is why the plain petroleum jelly barrier around the enclosure's upper interior does so much of the real escape prevention work.
One compliance note worth knowing: this species can't be legally shipped to Arizona or Florida due to state agricultural regulations, worth checking before ordering if you live in either state.

❓ Frequently Asked Questions
What size enclosure does a Madagascar hissing cockroach need?
5 gallons is the minimum for one animal or a small group; a 10 to 20-gallon tank or plastic tub suits a colony better. Floor space beats height for a ground-dweller.
What temperature and humidity does this species need?
75 to 85°F for general pet-keeping, room temperature above about 70°F is fine if you're not actively breeding. Breeding gets triggered around 85 to 95°F. Humidity should stay at 60 to 70%, maintained through daily misting and moisture-holding substrate.
What substrate should I use?
Coconut fiber, peat moss, or orchid bark at 2 to 3 inches, which suits their semi-burrowing habit. Add egg-crate stacks or cork bark for hides; they use them constantly.
Does a Madagascar hissing cockroach need special lighting?
No. It's nocturnal and photophobic, so darkness suits it and no special lighting is needed.
How do you stop a hissing cockroach from escaping?
Petroleum jelly, plain, smeared in a band around the top 2 to 3 inches inside the enclosure, plus a secure, tight-fitting lid. They climb smooth glass with ease, so without the barrier you will likely find roaches outside the enclosure sooner or later.
