Also known as: stinging caterpillar rash, caterpillar dermatitis, puss caterpillar sting, nausea (definition: feeling of sickness or urge to vomit)
📝 At a glance
Likely root causes: Direct contact with a stinging caterpillar's hairs or spines; Brushing against shed hairs on leaves, clothing, or laundry left outside; Handling caterpillars or working in gardens and trees where they live.
First thing to try: Remove embedded spines by pressing adhesive tape onto the area and lifting it off, repeating with fresh tape.
See a doctor if: Signs of a severe allergic reaction (call emergency services)
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Direct contact with a stinging caterpillar's hairs or spines
- Brushing against shed hairs on leaves, clothing, or laundry left outside
- Handling caterpillars or working in gardens and trees where they live
Change what you can
- Remove embedded spines by pressing adhesive tape onto the area and lifting it off, repeating with fresh tape.
- Wash the skin gently with soap and water; do not rub.
- Apply a cold compressA cloth soaked in warm or cold liquid, held on the skin. How to make a compress → to ease burning and swelling.
- Dab on a baking soda paste or calamine-type soother for itching.
- Take an oral antihistamine if itching is bothersome.
- Avoid scratching, which spreads the irritant and risks infection.

Removing the venomous hairs first is the safest and most effective starting step, before soothing the irritated skin.
How to do it ▾
Why it works: Stinging caterpillars leave behind hollow, venom-filled hairs in the skin; pressing tape onto the area and lifting it off pulls many of these hairs out, reducing ongoing irritation.
- Press the sticky side of tape firmly onto the affected skin.
- Lift the tape off in one motion, pulling out embedded hairs.
- Repeat with fresh tape a few times over the area.
- Wash the skin gently with soap and water afterward — do not rub or scratch.
5-10 minutes · Once, immediately after contact
Caution: Keep hands away from your eyes after handling a caterpillar or the affected area, since spines can injure the eye. Do not rub or scratch the area, which can drive hairs deeper and spread the irritant.
When to get help: Seek emergency care for facial or throat swelling, widespread hives, difficulty breathing, or spines in or near the eye.

A comforting follow-up step after removing the hairs, easing the burning and itching while the reaction settles.
How to do it ▾
Why it works: A cold compress reduces swelling and calms the burning sensation, while a baking soda or aloe paste soothes itching from the skin's irritant reaction.
- Apply a cold compress to the affected area for 10-15 minutes to ease burning and swelling.
- Mix a small amount of baking soda with water to make a paste, or use aloe vera gel, and apply to the skin.
- Take an age-appropriate oral antihistamine if itching is bothersome.
- Repeat the cold compress as needed through the day.
10-15 minutes per application · Every few hours as needed for the first day
Caution: Watch for signs of a more serious reaction, including spreading swelling, nausea, or fever. Some caterpillar species, like the puss caterpillar, cause more severe pain and reactions — treat cautiously and seek care if symptoms escalate.
When to get help: Seek emergency care for shortness of breath, difficulty swallowing, widespread hives, or spreading severe symptoms.

A preventive habit for families in areas with stinging caterpillars, reducing the chance of a sting in the first place.
How to do it ▾
Why it works: Most stinging caterpillar rashes happen from direct handling or brushing against hairs on leaves, clothing, or playground equipment, so teaching children to look-but-not-touch reduces exposure.
- Teach children to admire caterpillars without touching or picking them up.
- Check outdoor clothing and equipment for caterpillars or their hairs before use, especially in infested areas.
- Avoid leaning against trees or playground equipment known to have caterpillar activity.
- Wash outdoor laundry that may have been exposed to caterpillar hairs.
A few minutes of awareness · Ongoing during caterpillar season
Caution: This does not treat a sting that has already happened — see the tape-removal first-aid protocol for that. Some caterpillar hairs become airborne in high densities, so even without direct contact, sensitive individuals can react.
When to get help: Seek care for facial or throat swelling, difficulty breathing, or a widespread reaction after any caterpillar exposure.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health... In case of sickness 1cause should be ascertained, 2go to work intelligently to remove the disease. 3Unhealthful conditions should be changed, 4wrong habits corrected. 5Then nature is to be assisted in her effort 6to expel impurities and 7to re-establish right conditions in the system.”
🌿 Overview
Some caterpillars are covered with fine hairs or hollow spines that contain venom. When they touch skin — or when their shed hairs blow onto skin or clothing — they cause a stinging, burning rash. Reactions range from mild itching to intense pain with welts. The spines often break off in the skin and keep releasing irritant, so removing them is the first step to relief.
The reaction is a mix of mechanical irritation from the embedded spines and the venom or proteins they carry. Typical signs are immediate burning or stinging, redness, raised welts, and itching, sometimes in a pattern matching where the caterpillar touched. More potent species (such as the puss caterpillar) can cause severe pain, swelling, and occasionally nausea or headache. Rarely, sensitive people have a stronger allergic response.
Common signs
- Immediate stinging or burning where the skin was touched
- Red, raised welts or a rash, sometimes in stripes
- Itching that can be intense
- Tiny spines visible in the skin
- Sometimes swelling, and rarely nausea, headache, or trouble breathing
