Hisser Lab
Buy on AmazonShort reads, real sources
Each deep dive answers one question about hissing cockroach biology and backs it with the actual literature. They are the research behind the care guide’s field notes, written from the primary literature.

Are the mites on a hissing cockroach harmful?
The tiny mites that ride along, what they are, and whether they affect the roach, your pets, or your home.
How does a cockroach make sound by breathing?
The spiracle-driven hiss mechanism, and what the three hisses signal.
How do males fight, and do the horns decide?
Agonistic behavior, dominance, and the pronotal horns.
Do hissing cockroaches live in groups?
Gregarious aggregations, male dominance hierarchies, and how they signal by smell, touch, and sound.
What lives inside a hisser that helps it digest?
Gut microbes and the Blattabacterium symbiont that recycles nitrogen.
What do Madagascar hissing cockroaches eat?
The wild diet of fallen fruit, the captive menu, and what to avoid.
Do they really give live birth?
Ovoviviparity: eggs hatch inside the female, which is not mammalian live birth.
Why is there no caterpillar stage?
Incomplete vs complete metamorphosis, the butterfly contrast kids know.
Why does a freshly molted hisser turn white?
Ecdysis, the soft teneral stage, and cuticle hardening.
How does temperature change how fast they grow?
Ectotherm development rate, and how keepers slow or speed a colony.
Are all “hissing cockroaches” one species?
Gromphadorhina taxonomy, hybrids, and mislabeling in the trade.
Why can’t a tropical roach take over a house?
The climate limits that keep a tropical insect from establishing indoors.
Have a question we haven't answered?
Send it over. If it is a good one, we will dig through the research and turn it into a new deep dive, then let you know when it is up.
We read every question. We cannot promise a personal reply, but the questions people ask most become deep dives.
How we make these
- Each deep dive answers one question and cites primary literature by name, with links.
- Where the science is unsettled, we say so instead of picking a tidy answer.
- Facts stay identical to the rest of the site.
