Millipedes are worm-like bugs called arthropods. Certain types of millipedes release a harmful substance (toxin) if they are threatened or if you handle them roughly.

• Millipede venom

• Millipedes

If the millipede toxin gets on the skin, symptoms may include:

• Staining of the skin (turns brown)
• Intense burning or itching of skin
• Blisters

If the millipede toxin gets in the eyes, symptoms may include:

• Blindness (rare)
• Inflammation of the membrane lining the eyelids (conjunctivitis)
• Inflammation of the cornea (keratitis)

Wash the exposed area with plenty of soap and water. DO NOT USE ALCOHOL TO WASH THE AREA. Wash eyes with plenty of water if any toxin gets in them. Notify the health care provider if any toxin got in the eyes.

Determine the following information:

• The patient's age, weight, and condition
• The name of the insect if known
• The time the person was exposed to the toxin

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

If possible, bring the millipede to the emergency room for identification.

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate.

The symptoms usually go away within 24 hours after exposure. The outlook may be more serious if the eyes were involved.
