Are Bark Scorpions Dangerous? What Phoenix Residents Need to Know
The Arizona bark scorpion is the most venomous scorpion in North America. Here's what you need to know about their stings and how to protect your family.
The Danger of the Arizona Bark Scorpion
If you live in Phoenix, Scottsdale, Gilbert, or anywhere in the Valley, you've likely heard horror stories about bark scorpions. The Arizona bark scorpion (*Centruroides sculpturatus*) holds the title of the most venomous scorpion in North America.
But just how dangerous are they?
The Symptoms of a Bark Scorpion Sting
Unlike a bee sting or a sting from a less venomous scorpion (like the Desert Hairy Scorpion), a bark scorpion sting injects a powerful neurotoxin. Symptoms typically include:
1. Immediate, severe pain at the sting site.
2. Numbness and tingling (often described as feeling like an electric shock) that travels up the limb.
3. Hypersensitivity to touch or temperature at the sting site.
In severe cases — particularly in young children, the elderly, or those with compromised immune systems — symptoms can escalate to:
What to Do If You're Stung
1. Stay calm. Most adult stings do not require antivenom, though they are incredibly painful.
2. Wash the area with soap and water.
3. Apply a cool compress to reduce pain.
4. Take over-the-counter pain medication (like ibuprofen).
5. Seek immediate medical attention if the victim is a child or elderly, or if severe symptoms (muscle spasms, difficulty breathing) develop. Do not hesitate to call 911 or visit an ER.
Why You Can't Ignore Bark Scorpions
Bark scorpions are unique because they are excellent climbers. They can scale block walls, climb into cribs, and drop from the ceiling. They also congregate in groups during the winter.
Because of the severe pain of a sting and the risk to children and pets, professional scorpion control is essential. Learn how our specialized barrier treatments eliminate bark scorpions.
