No venom, no sting

Millipedes don't bite or sting and have no venom. Many do secrete defensive chemicals when stressed, so wash your hands after handling and keep them away from your eyes and mouth.

Secretes benzoquinones

Stains skin brown for several days and stings badly in the eyes or on broken skin. Wash your hands after handling, don't rub your face, and keep it well away from small children.

About

A beautiful millipede ringed in red, black, and yellow 'rainbow' bands. A touch more demanding than the African giants: it dislikes temperature swings (keep a steady 72-77°F) and wants high humidity (70-90%) over deep (7-10 cm) soil-based substrate with leaf litter and rotting wood. Docile and not prone to heavy defensive secretion. Detritivore — substrate is most of its diet, plus a calcium source. Harmless; wash hands after handling.
