Quick answer: a millipede bite does not happen, because millipedes cannot bite. They can release an irritating secretion that causes burning and itching on skin. If it reaches the eye, it can cause redness, swelling and pain. Wash skin with soap and water, and flush eyes with water straight away. Larger centipedes, by contrast, can give a painful bite.
Millipedes are slow, harmless-looking arthropods. People often mistake them for worms or small snakes. Understanding what they do release helps you react calmly.
What Is a Millipede?
Millipedes belong to the class Diplopoda. Most segments carry two pairs of legs. Many are brown or dark, and some curl into a spiral or ball when disturbed. They feed mainly on damp, decaying plant matter.
Do Millipedes Bite or Poison?
The MSD Manual states that millipedes cannot bite. Their defence is a secretion. It irritates skin, causing burning and itching. It is a contact irritant, not a venom injected through the skin.
Millipede vs Centipede
| Feature | Millipede | Centipede |
|---|---|---|
| Legs per body segment | Two pairs on most segments | One pair |
| Bites | No | Larger ones can |
| Main risk | Skin or eye irritation from secretion | Painful bite with swelling and redness |
| First aid | Soap and water; flush eyes | Cold pack wrapped in cloth |
First Aid for Millipede Secretion
For skin contact, wash the secretion off with plenty of soap and water. If a skin reaction develops, the MSD Manual suggests a corticosteroid cream. A pharmacist can advise on an over-the-counter option.
For eye contact, flush the eye with water right away. Do not rub it. Seek medical care if pain or redness persists.

Safety: Children, Pets and Allergies
Teach children not to pick up millipedes, and wash their hands afterwards. Avoid touching the eyes after handling one. Seek urgent care for trouble breathing, facial swelling or a spreading rash. Contact a vet if a pet mouths a millipede and drools or paws at its face.
