The objective is to remove irritating caterpillar hairs. On skin, apply adhesive tape (such as duct or masking tape) to the site, then pull off. Repeat as needed until all hairs are removed. Follow with calamine lotion, and apply ice to the affected area.

Eyes should be flushed immediately with plenty of water before seeking professional medical care. If respiratory symptoms develop following inhalation of caterpillar hairs, administer beta-agonist inhalers or antihistamines (if available), then seek professional medical care.

Before calling the emergency number determine the following:

• Patient's age, weight, and condition
• Identity of the caterpillar, if possible
• Time of the incident

See Poison Control Centers for telephone numbers and addresses. Poison Control may instruct you to go to the hospital for further care. If possible, bring the caterpillar to the emergency room for identification. If an emergency situation exists, call your local emergency number, such as 911.

Emergency treatment may include:

Treatment for anaphylaxis if required.

Skin exposures:

• Ensure all hairs are removed
• Topical or oral medications to control pain and itching

Eye exposures:

• Flushing eyes with water or saline
• Topical anesthetic drops
• Detailed eye examination

Inhalation exposures:

• Supplemental oxygen
• Inhaled bronchodilator medications
• Antihistamines

The outcome is generally very good, and death is exceedingly rare.
