What happens if you get stung by a bald-faced hornet?

Published in Insect Sting Management 3 mins read

A bald-faced hornet sting typically results in immediate pain and localized reactions, which can be managed with proper first aid. While generally not life-threatening for most people, it's important to know how to treat a sting and recognize signs of a more severe reaction.

Immediate Effects and Common Symptoms

When a bald-faced hornet stings, you'll likely experience a sharp, painful sensation at the site. This pain can be intense and is often followed by other common symptoms:

  • Localized Pain: An acute, throbbing pain right where you were stung.
  • Swelling: The area around the sting will usually swell and may feel firm to the touch.
  • Redness: The skin around the sting site will become red.
  • Warmth: The affected area may feel warm to the touch.
  • Itchiness: As the initial pain subsides, itchiness often develops around the sting site.

First Aid and Home Care

Managing a bald-faced hornet sting primarily involves addressing the pain and itchiness, and preventing infection. Here's what you can do:

  • Remove the Stinger (if visible): Although hornets generally do not leave their stingers behind like honey bees, it's good practice to check. If present, remove it quickly by scraping it out with a fingernail or credit card, rather than pinching, which can push more venom into the skin.
  • Clean the Area: Wash the sting site thoroughly with soap and water to prevent infection. It's important to keep the area clean in the days following the sting.
  • Reduce Swelling: Apply a cold compress or ice pack wrapped in a cloth to the affected area for 10-20 minutes at a time. Elevating the stung limb can also help reduce swelling.

Managing Pain and Itchiness

To alleviate the discomfort associated with the sting, consider the following treatments:

Symptom Recommended Treatment
Pain Take an over-the-counter pain reliever such as acetaminophen (e.g., Tylenol) or ibuprofen (e.g., Advil, Motrin).
Itchiness Consider taking an antihistamine (like diphenhydramine) or applying a paste made from baking soda and water to the sting site. Calamine lotion can also provide relief.

When to Seek Medical Attention

While most bald-faced hornet stings can be treated at home, certain situations warrant immediate medical attention.

  • Signs of a Severe Allergic Reaction (Anaphylaxis): This is a medical emergency. Call emergency services immediately if you experience any of the following symptoms, even if they seem mild at first:
    • Hives, itching, or flushed or pale skin.
    • Difficulty breathing or wheezing.
    • A weak, rapid pulse.
    • Dizziness or fainting.
    • Swelling of the face, throat, or tongue.
    • Nausea, vomiting, or diarrhea.
    • A sudden feeling of dread or impending doom.
    • A significant drop in blood pressure (shock).
  • Multiple Stings: Many stings at once can overwhelm the body even in individuals who are not allergic, leading to a toxic reaction. Seek medical help if you've received numerous stings.
  • Sting in Sensitive Areas: If stung in the mouth, nose, or throat, swelling could interfere with breathing, requiring immediate medical evaluation.
  • Signs of Infection: If the redness, swelling, or pain worsens after 24-48 hours, or if you develop pus or fever, seek medical attention as it could indicate an infection.
  • Children or Individuals with Pre-existing Conditions: Young children, the elderly, or those with heart or respiratory conditions may be more vulnerable to sting reactions and should be monitored closely.
