🐝 Yellow Jacket vs. Bald-Faced Hornet: Which One Hurts More?
They both have wings. They both can be aggressive. And both can deliver a painful sting.
But Yellow Jackets and Bald-Faced Hornets are not the same insect.
Here’s what Calgary homeowners should know 👇
🟡 YELLOW JACKET
Size: Usually about 10–16 mm long.
Appearance: Bright yellow and black with a relatively smooth, slender body.
Where they nest: Often underground, inside wall voids, under decks, in cracks, or other protected spaces.
Stinging: Yellow Jackets can sting repeatedly because their stinger is not left behind.
Pain: Their sting causes an immediate sharp, burning pain, followed by redness, swelling and tenderness. Multiple stings can produce much more intense symptoms.
⚠️ One important thing: Yellow Jackets can become extremely defensive when their nest is disturbed.
⚪ BALD-FACED HORNET
Size: Larger and more robust, usually around 12–19 mm long.
Appearance: Mostly black with distinctive white/ivory markings on the face and abdomen.
Where they nest: They commonly build large paper nests in trees, shrubs, under eaves, and other elevated locations.
Stinging: Like Yellow Jackets, they can sting repeatedly.
Pain: Their sting can be very painful, with a strong burning sensation, swelling and tenderness.
And because Bald-Faced Hornets aggressively defend their nest, disturbing one can result in multiple hornets attacking at once.
🔥 SO WHICH STING HURTS MORE?
There isn't a reliable scientific rule that says one always hurts more.
Pain varies from person to person and depends on the location and number of stings.
The bigger concern isn't simply the pain — it's multiple stings and allergic reactions.
🚨 Seek emergency medical attention if someone develops:
Difficulty breathing
Swelling of the face, lips or throat
Dizziness or fainting
Widespread hives
Rapidly worsening symptoms
🏠 THE BIGGEST MISTAKE?
Trying to remove an active nest yourself.
A nest that looks small from the outside can contain many defensive workers.
If you see wasps repeatedly entering and leaving the same hole, crack, wall void or nest, don't block the entrance or disturb the nest before it's treated.
🐝 Know the difference. Know the risk. Stay safe.
