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

One of the giants of the hobby — a long, spike-tailed Thai millipede that can approach a foot in length. Wants a humid (70-90%), well-ventilated terrarium at room temperature (70-82°F) with deep, moisture-holding substrate topped by oak leaf litter and rotten hardwood, which forms the bulk of its diet. Substrate should be at least a couple of body-lengths deep for burrowing and molting. Offer occasional veg and a calcium source (cuttlebone). A docile, slow detritivore; wash hands after handling as with any millipede.
