A bite from a large Scolopendra is rarely medically dangerous, but it is genuinely and memorably painful — and “rarely dangerous” is not the same as “safe”. The honest version is that most bites produce severe local pain that fades within a day or two, a small minority produce complications worth a doctor’s attention, and a handful of serious cases exist in the medical literature.
Quick answer
- The usual outcome is intense local pain, redness, swelling and warmth, resolving in roughly one to two days.
- Pain and swelling can linger up to a week, and occasionally as long as three weeks.
- Mild systemic symptoms — headache, nausea, anxiety, palpitations — are reported and are usually short-lived.
- Rare but documented complications include local tissue necrosis, lymphangitis, secondary infection, rhabdomyolysis with kidney injury, cardiac events and anaphylaxis.
- There is no specific antivenom. Treatment is supportive.
- Deaths are recorded in the literature but are extremely rare.
How the bite actually works
A centipede does not bite with its mouth. The venom is delivered by forcipules — the first pair of legs, modified over evolutionary time into curved, hollow claws that sit under the head. That is why the wound is usually two puncture marks a short distance apart, and why a large animal can drive them deep.
The venom is not a single toxin. It is a complex mixture including cytolytic proteins that damage cell membranes and serotonin, which is part of why the pain is so disproportionate to the size of the wound. The animal is not trying to kill you; it is trying to make you let go, and the venom is very good at that job.
What is common, what is rare, and what needs a doctor
| What happens | Typical course | |
|---|---|---|
| Common | Severe local pain, redness, swelling, warmth, itching around the puncture sites | Peaks early, largely settles in 1–2 days |
| Fairly common | Headache, nausea, anxiety, palpitations, swollen local lymph nodes | Hours, self-limiting |
| Uncommon | Blistering, prolonged swelling, small area of skin necrosis at the puncture sites | Up to 3 weeks, usually heals without surgery |
| Rare | Cellulitis or deeper secondary infection, lymphangitis | Needs medical treatment |
| Very rare | Anaphylaxis, rhabdomyolysis with kidney injury, cardiac events | Medical emergency |
When to stop managing it yourself
Wash the site, keep it clean, take an ordinary analgesic if you need one, and watch it. Get medical attention if any of the following appear:
- Difficulty breathing, throat or facial swelling, widespread hives, faintness — treat as an emergency.
- Spreading redness, red streaking away from the wound, fever, or pain that worsens after the first day rather than improving.
- Dark or reduced urine, or severe muscle pain.
- Chest pain or palpitations that do not settle.
- Any bite to the face, or a bite in a child, an older adult, or anyone with a significant heart or kidney condition.
- An out-of-date tetanus vaccination.
One study of centipede envenomation found severe hypersensitivity reactions in about 5% of cases, which is a useful number to hold in mind: not common, not negligible. If you have had a serious reaction to an insect sting before, that is a reason to think harder about whether this is your animal.

The part that actually keeps you safe
Almost every bite in the hobby comes from the same three situations, and all three are avoidable.
Reaching into the enclosure
Do not. Use long forceps for everything — feeding, spot cleaning, rearranging. A centipede is faster than your reflexes over short distances, and it will defend a burrow entrance.
Handling
There is no safe way to hold a large Scolopendra, and no husbandry reason to. Every keeper who has been bitten badly was, at that moment, doing something optional. We say the same thing on every centipede listing we sell: venomous, advanced keepers only, never handled.
Escapes
The bite that catches people out is the one at 3am from an animal that got out a week ago. Escape-proofing is a safety measure before it is a husbandry measure — see centipede enclosure setup for how to build one that actually holds.
Should you keep one anyway?
Plenty of people should. A Scolopendra is one of the most rewarding invertebrates in the hobby — genuinely intelligent-looking, fast, and beautiful in a way photographs undersell. But it is a hands-off display animal for someone who is calm around risk and disciplined about tools.
If you want a large, striking myriapod you can actually pick up, the answer is a millipede, not a centipede. They are not close relatives and they are not interchangeable — we set the differences out in centipede vs millipede, and the care side in millipede care. If you have decided a centipede is right for you, centipede care covers day-to-day keeping and our current centipedes for sale lists what we have, with the size and provenance stated on each listing.

Common questions
How painful is a centipede bite?
Severe, and out of proportion to the size of the wound. Keepers commonly describe it as worse than a wasp sting and comparable to a bad hornet sting, concentrated at the puncture sites and radiating up the limb. It usually peaks quickly and eases substantially within a day.
Can a centipede bite kill you?
Deaths are recorded in the medical literature but are extremely rare, and the risk to a healthy adult from a captive centipede is very low. The realistic dangers are anaphylaxis in a sensitised person and secondary infection of the wound, not the venom itself.
Is there an antivenom for centipede bites?
No. There is no specific antivenom in use. Treatment is supportive — wound care, pain relief, and management of any complication that develops.
What should I do immediately after a bite?
Move away from the animal and secure the enclosure first. Wash the site with soap and water, keep it clean and elevated if it is swelling, and take an ordinary painkiller if you need one. Then watch for the warning signs above.
Are pet centipedes aggressive?
They are defensive rather than aggressive. A centipede bites what it cannot escape from or what corners it. Almost all bites in captivity happen during handling or an unplanned encounter after an escape, which is why tool discipline and a sealed enclosure matter more than temperament.
