Madagascar Hissing Cockroach

A 10-gallon terrarium with a tight, secure lid is a reasonable starting point for a small colony of 10 to 20 individuals. For larger colonies (which they become quickly), upgrade to a 20-gallon or larger rubbermaid-style container with a ventilated lid. Madagascar hissing cockroaches are exceptional climbers on rough surfaces - any textured wall, wood, or mesh can be scaled. Smooth glass or smooth plastic sides at least 10 to 12 inches tall will prevent escape. Petroleum jelly applied near the top edge (a "barrier" band) is a secondary escape-proofing method some keepers use.

Use coconut fiber or bark chip substrate 2 to 3 inches deep. Add cork bark tubes, egg carton sections stacked vertically, or cardboard tubes - these create the dense, structured hides this social species prefers. They pile together in these structures during the day and emerge at night.

Temperatures of 75 to 90 degrees F are ideal. Ambient room temperature above 70 degrees F usually suffices without supplemental heating. Moderate humidity of 50 to 70% is appropriate. Avoid overly wet conditions, which encourage mold.

Madagascar hissing cockroaches are detritivores that are not picky. The core of their diet is fresh fruits and vegetables: apple slices, banana, carrot, sweet potato, leafy greens (collard greens, romaine), and cucumber are all accepted eagerly. Rotate offerings to provide variety.

Supplement with a protein source: dry dog or cat kibble (grain-free or basic formulation) provides the amino acids needed for healthy molting and breeding. Oatmeal, dry whole-grain cereal, and bran are also accepted as carbohydrate supplementation.

Remove all fresh food within 24 to 48 hours before mold develops. Provide cuttlebone or crushed eggshell pieces constantly - calcium is critical for successful molting in cockroaches as in all invertebrates. Fresh water must be available at all times, but use a shallow dish with a sponge, cotton ball, or pebbles inside to prevent smaller individuals from drowning.

Madagascar hissing cockroaches are social, colony-living animals - their primary enrichment comes from appropriate group dynamics. They maintain a social hierarchy, with males competing for dominance through physical pushing contests and the remarkable hissing displays. Watching these contests is genuinely fascinating. Males hiss aggressively during territorial and mating encounters; both sexes produce a startle hiss when suddenly disturbed.

They are completely harmless to humans: they do not bite, they have no venom, and they do not sting. They are one of the best invertebrate species for children and beginners due to their large size, slow movement, predictable behavior, and tolerance of handling. Allow them to walk across open palms - they are unhurried and easy to manage.

Cork bark tubes, stacked egg carton sections, and cardboard tubes give the colony the dense social spaces they seek naturally. This is especially important for juveniles and molting adults, who need secure, enclosed spaces to complete their molts safely. A well-furnished enclosure with adequate hiding space dramatically reduces molting failures.

Madagascar hissing cockroaches are exceptionally hardy with few health problems when kept in appropriate conditions. The most common issues are all avoidable: overcrowding (which causes stress, increased male aggression, and premature deaths), failed molts from insufficient humidity or inadequate hides, and mite infestations from a too-wet substrate.

Mites show as tiny white or brown specks visible on the cockroaches or moving through the substrate. Treat by removing all cockroaches, discarding the old substrate completely, cleaning and drying the enclosure, and starting fresh. Increase ventilation and allow the substrate to dry slightly between mistings.

Escaped cockroaches are the most serious concern for many keepers: check the lid and escape barrier routinely. Males fight - in overcrowded conditions with too few hides, subordinate males can be killed. Provide enough structure that all individuals can find secure shelter simultaneously. This species can live 2 to 5 years, and colonies grow rapidly once established.
