Millipede at a glance

Millipedes — including the popular giant desert and African millipedes — are calm, slow, low-cost pets that gently curl around your fingers. They burrow, munch decaying leaves, and ask very little. A wonderful, low-stress first "bug" for gentle kids (with hand-washing).

Hissing Cockroach at a glance

Madagascar hissing cockroaches are clean, gentle, wingless giants that calmly walk across your hand and "hiss" when surprised. They're cheap, hardy, nearly odorless, and a brilliant, brave first bug — and far friendlier than their reputation suggests.

What really makes them different

Gentle and handleable

Both of these are calm, gentle bugs that careful kids can watch and, with clean hands, hold for a moment. A millipede moves slowly and curls into a coil when shy. A Madagascar hissing cockroach is clean and harmless and makes a fun hissing sound to say 'back off.' Neither bites. The millipede can release a mild defensive fluid if stressed, so wash your hands after handling either one, every time.

Setup and escapes

Both like a warm tub with damp bedding and hiding spots. Millipedes burrow and eat decaying leaves and veggies, living a long time — about 5-10 years. Hissing cockroaches eat fruits and veggies and live about 2-5 years. Here is the big one: hissing roaches are fast, expert climbers that scale smooth glass, so you need a tight, escape-proof lid. Millipedes can stretch and climb too, so clip the lid down snugly for both.

🐾 Our quick take: Pick a millipede for a slow, gentle burrower that lives a long time and is very calm to watch. Pick a hissing cockroach for a clean, friendly bug with a fun hiss — just secure that lid tightly.

❓ Common questions

Do they bite or sting?

Neither bites or stings. Millipedes may release a mild defensive fluid, so always wash your hands after handling.

Which lives longer?

Millipedes do — about 5-10 years, compared with about 2-5 years for a hissing cockroach.

Will the cockroach escape?

It can if the lid is loose. Hissing cockroaches climb smooth glass easily, so use a tight, escape-proof lid.
